This application claims priority under 35 U.S.C. § 120 as a continuation of U.S. application Ser. No. 18/673,514 filed on May 24, 2024 (to be issued as U.S. Pat. No. 12,372,316 on Jul. 29, 2025), which is a continuation of U.S. application Ser. No. 18/178,166 filed on 3 Mar. 2023 (issued as U.S. Pat. No. 11,994,356 on May 28, 2024), which is a continuation of U.S. patent application Ser. No. 17/696,054 of the same title and filed on 16 Mar. 2022, the contents of which are incorporated herein by reference in its entirety.

This disclosure relates to handgun components and more particularly to a takedown lever for a handgun, a takedown safety mechanism for a handgun, and a trigger shoe for a firearm trigger

Firearms design involves many non-trivial challenges. Traditionally, semiautomatic handguns have been made with a metal frame that includes the grip portion and a body portion with rails along a top surface. The grip portion defines a magazine well into which a magazine is installed. More recently, some semiautomatic handguns have a polymeric grip module that retains a metallic receiver in an open top of the grip module, where the receiver houses the fire control components and includes rails for the slide. Whether a metal frame or a polymeric grip module with drop-in receiver, a slide mounts to and can reciprocate longitudinally along rails that extend along the top of the frame or receiver. A takedown lever can be moved to a takedown position to remove the slide for cleaning and maintenance.

One aspect of the present disclosure relates to a takedown lever that rotates counterclockwise from a firing position to a takedown position, as viewed looking at the left side of the handgun. This rotation direction is opposite that of existing takedown levers. Advantageously, the takedown lever can be used as a thumb rest when firing the handgun. Since the lever rotates counterclockwise rather than clockwise to the takedown position, the lever is stable for use as a rest with downward pressure applied by the user.

Another aspect of the present disclosure relates to a takedown lever assembly that includes a safety block. When the takedown lever is moved to the takedown position, the safety block moves rearwardly so that it protrudes into the magazine well. The safety block may additionally or alternately move against the trigger body to prevent the trigger from pivoting (i.e., from being pulled) when the takedown lever is in the takedown position.

A further aspect of the present disclosure relates to a trigger assembly that includes a trigger body and trigger shoe.

The features and advantages described herein are not all-inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the drawings, specification, and claims. Moreover, it should be noted that the language used in the specification has been selected principally for readability and instructional purposes and not to limit the scope of the disclosed subject matter.

These and other features of the present embodiments will be better understood by reading the following detailed description, taken together with the Figures herein described. For purposes of clarity, not every component may be labeled in every drawing. Furthermore, as will be appreciated, the figures are not necessarily drawn to scale or intended to limit the present disclosure to the specific configurations shown. In short, the Figures are provided merely to show example structures.

Disclosed is a takedown lever for a semiautomatic handgun. In accordance with one embodiment, the takedown lever rotates counterclockwise from the shooting position to the takedown position as viewed looking at the left side of the handgun. For example, in the takedown position, the lever wing extends upward along the slide from the lever shaft; in the shooting position, the lever extends horizontally and abuts the frame. Accordingly, when the lever is in the shooting position the user may use the takedown lever as a thumb rest. In some embodiments, the takedown lever can be shaped to enhance its use as a thumb rest.

Also disclosed is a takedown safety for a semiautomatic handgun. In one example, a block or lever is displaced rearwardly when the takedown lever is moved to the takedown position. When the mechanism includes a block, for example, a proximal end of the block protrudes into the magazine well and prevents installation of a magazine into the magazine well while the takedown lever is in the takedown position. Similarly, the takedown lever cannot be moved to the takedown position when a magazine is in the magazine well. This safety feature prevents the user from loading the gun while the takedown lever is in the takedown position, such as during cleaning.

In some embodiments, the lever or block abuts or is positioned closely adjacent to part of the trigger body when the takedown lever is in the takedown position. For example, a block moves to the front face of the trigger body above the trigger pin. Accordingly, the trigger cannot rotate and is blocked from being pulled by the user. One such embodiment is particularly useful in a hammer-fired handgun where blocking trigger rotation also prevents disengagement of the sear and therefore prevents release of the hammer. Accordingly, even if the gun contains a round in the chamber, the user cannot pull the trigger while the takedown lever is in the takedown position.

Further disclosed is a trigger assembly that includes a trigger body and a trigger shoe. In one example, the trigger shoe attaches to the trigger body using a snap fit. The removable trigger shoe enables the user to change the trigger shoe as desired for different profile, appearance, or material, and the user may do so without the need for armorer training.

Safety continues to be an important challenge for firearms designers. Handguns can be made with external safety levers that are activated by the user. Handguns can also have one or more internal safeties that prevent discharge when the firearm is dropped, for example.

One non-trivial issue of firearms design and performance pertains to preventing unintended discharge during the takedown and cleaning process. When proper takedown protocol is followed, cleaning and servicing the firearm is a safe event. According to recognized safety protocol, the user first releases the magazine from the magazine well, followed by racking the slide to eject the chambered round (if present), and visually checking the chamber to ensure no ammunition is present. Finally, the user decocks the action or pulls the trigger full cycle to release the spring tension on the striker or hammer. From this condition, the user may proceed to disassemble or “take down” the handgun for cleaning or service

Unfortunately, however, not all gun owners follow safe protocol and the result can be an unintentional discharge during the course of cleaning a handgun. For example, after releasing the magazine, the user may pull the trigger to decock the action without first clearing the chamber. If a round is chambered, pulling the trigger can fire the gun. Also, with the slide removed, some users may attempt to install a magazine into the magazine well, such as to view how the loaded magazine interacts with other components of the action. Again, an unsafe condition and unintentional discharge can result.

In the interest of preventing unintentional discharges when cleaning a handgun, a safety mechanism can prevent the user from unsafe actions when field stripping or cleaning the handgun. For example, one such safety prevents release of the hammer or striker when the slide is removed from the handgun. In another example, a safety prevents removing the slide when the magazine contains a magazine in the magazine well. Despite these advances, a need still exists for new safety mechanisms in handguns.

To address this need and others, the present disclosure relates to a safety mechanism for semiautomatic handguns. One aspect of the disclosure is directed to a takedown lever configured to rotate in a counterclockwise direction from the shooting position to the takedown position as viewed looking at the left side of the gun. Another aspect of the disclosure is directed to a takedown assembly for a hammer-fired handgun. In one example, the takedown lever engages and pivots a block having arms that extend rearwardly along sides of the trigger body. When the takedown lever is moved to the takedown position, the block is shifted rearwardly into contact with or closely adjacent to a front part of the trigger, blocking trigger rotation. At the same time, a proximal end portion of the arm or arms extends into the magazine well a distance sufficient to prevent a magazine from being installed in the magazine well. Similarly, the takedown lever is blocked by a magazine from moving to the takedown position if a magazine is present in the magazine well. The takedown assembly according to the present disclosure can prevent an unsafe condition during takedown by requiring the user to remove the magazine prior to moving the takedown actuation lever to the takedown position. The assembly also can block rotation of the trigger when the takedown actuation lever is in the takedown position. One additional aspect of the present disclosure relates to a trigger that includes a trigger body and a trigger shoe that can be removably attached to the trigger body, such as with a snap fit. Various aspects of the present disclosure can be utilized individually or in combination as part of a handgun. Numerous configurations and variations will be apparent in light of this disclosure.

As will be appreciated in light of this disclosure, and in accordance with some embodiments, a takedown assembly and its components can be used with a semiautomatic handgun, particularly one that is hammer-fired. In accordance with some example embodiments, a takedown assembly can be part of a semiautomatic handgun chambered in .22 LR, .380 Auto, 9 mm Luger, .357 SIG, 10 mm Auto, .40 S&W, .45 ACP ammunition, or any other suitable ammunition. As will further be appreciated, a removable trigger shoe in accordance with embodiments of the present disclosure can be used in handguns and long guns alike. Other suitable host firearms will be apparent in light of this disclosure.

As used herein, the term “frame” refers to the serialized component of a handgun that houses components of the fire control assembly. In metal handguns, for example, the frame may include the grip portion, trigger guard, and a portion of the frame that extends along the bottom of the barrel. In other handguns having a polymeric grip module, for example, the frame refers to the serialized metal component that can be secured into the open top portion of the grip module and along which the slide reciprocates.

While generally referred to herein as a takedown assembly for consistency and ease of understanding the present disclosure, the disclosed takedown assembly and its components are not limited to that specific terminology and alternatively can be referred to using other terms. For example, the takedown lever alternately can be referred to as a takedown actuation lever, a takedown tab, or other terms. In another example, the safety bar can alternately be referred to as a takedown safety lever, a takedown safety, a safety linkage, or other terms. As will be further appreciated, the particular configuration of a takedown assembly configured as described herein may be varied, for example, depending on whether the handgun is hammer-fired or striker-fired. Numerous configurations and embodiments will be apparent in light of this disclosure.

illustrates a side view of the left side of a handgunthat includes a takedown lever assembly, in accordance with an embodiment of the present disclosure. The takedown lever assemblyincludes a takedown actuation leverthat is shown in a first position or firing position. The handgunincludes a polymeric grip modulewith a grip portionthat defines a magazine wellconfigured to receive a magazine. In this example, a magazineis installed in the magazine well. A receiver(not visible; shown in) is retained in a top of the grip moduleand includes slide rails that engage the slide. Components of the fire control group are attached to or extend through the receiver, including the trigger, slide catch lever, and takedown actuation lever. A slideis mounted on the top of the receiverand can reciprocate longitudinally along the slide rails during use.

illustrate a front perspective view and a side view, respectively, showing a takedown lever assembly, a trigger assembly, and other components of the handgunof. In this example, the grip moduleis omitted to more clearly show the receiverand components of the fire control group. In, a magazineis installed.

The takedown lever assemblyincludes the takedown actuation leverand a safety block. The trigger assemblyincludes the trigger, a trigger pin, and a trigger spring(not visible; shown in, &). Other components are part of the handgun and function with the trigger assemblyand/or the takedown lever assembly, as will be appreciated.

As can be seen in, the takedown actuation leverincludes a lever shaftthat extends laterally through the receiver. The takedown actuation leverincludes a lever wingon the outside of the receiver. The lever wingis connected to the lever shaftand extends along the outside of the receiver. A camextends radially outward from part of the lever shaft. The lever shaft, cam, and lever wingtypically are formed as a single monolithic component, but it is possible that these parts can be made as separate components and assembled. In this example, the takedown actuation leveris in the firing position and the camextends radially outward from the lever shaft. The lever wingfunctions as an interface or grip for the user to rotate the takedown actuation lever. In the firing position as shown, the top of the lever wingextends horizontally along a bottom margin of the slide.

The triggercan rotate between a resting position and a pulled position about a trigger pinextending laterally through the trigger bodyand safety block. A trigger shoeattaches to a front, lower portion of the trigger bodyand is positioned for manipulation by the user.

shows a side view of part of the handgun with the receivershown transparent and the grip module omitted for clarity, in accordance with an embodiment of the present disclosure. In, the takedown lever assemblycan be seen, and includes the takedown actuation leverand safety block. The takedown actuation leveris in the firing position and the triggeris in the resting position. The trigger bodyextends upward between laterally spaced arms of a safety block, which is discussed in more detail below. The trigger pinextends through the trigger bodyand through an elongated pin openingthrough the safety block. When the takedown actuation leveris in the firing position, such as shown here, the trigger pinoccupies a proximal or rearward portion of the pin opening. Note also that the proximal endof the safety blockdoes not interfere with the magazine, which is installed in the magazine well.

shows a side view of the takedown lever assembly, trigger assembly, and part of a magazinewith the takedown actuation leverin the firing position and the triggerin the resting position. The takedown actuation leveris shown as transparent in this example. The triggeris biased to the resting position by a trigger springbetween the safety blockand an upper end portion of the trigger body. At the same time, the trigger springbiases the safety blockto the forward or non-blocking position. The trigger pinoccupies a proximal end portion of the elongated pin openingthat extends through the safety block. A trigger bar or sear leverengages the trigger bodyabove the trigger pin. The upper portionof the safety blockis spaced axially from the trigger body, which allows the triggerto pivot if pulled. Pulling the triggerwould cause the trigger to rotate about the trigger pinagainst the force of the trigger spring, in addition to other forces. Note that the trigger springand sear levergenerally have the same general vertical position with respect to the trigger.

The camhas first and second portions that protrude radially away from the lever shaft. The first portionof the cam, which has a first diameter, contacts a front of the safety block. The safety blockis firmly blocked by the camfrom moving forward and provides a solid stop for the trigger spring. The second portionof the camhas a second diameter that is greater than the first diameter.

illustrates a bottom, front, and side perspective view showing components of the takedown lever assemblyand trigger assembly, in accordance with an embodiment of the present disclosure. Here, the takedown actuation leveris in the firing position and the triggeris in the resting position. The trigger bodyis positioned between a first armand a second armof the safety block. Note that a top of the lever wingis generally oriented horizontally. The first portionof the camextends rearward from the lever shaftand abuts the frontof the safety block. The second portionof the camextends downward from the lever shaft. The safety blockis in the forward or non-blocking position as evidenced by the trigger pinoccupying the rear of the elongated pin opening. A second camis spaced laterally from the cam(or first cam) and also contacts the frontof the safety block. Note that the second camhas a portion extending down from the lever shaftthat has a reduced radius compared to the second portionof the first cam. This reduced radius permits assembly of the handgun components by providing clearance between the second camand the safety blockwhen the takedown actuation leveris in the takedown position.

illustrates a top view showing components of the takedown lever assemblyand trigger assemblywith the takedown actuation leverin the firing position and the triggerat rest, in accordance with an embodiment of the present disclosure. The lever wingextends rearwardly along the safety block. The first camand second camextend rearward from the lever shaftand contact the front of the safety block. The first camis generally aligned with the first armand the second camis generally aligned with the second arm. The frontof the safety blockincludes a protrusionthat extends forward and contacts the lever shaftbetween the first and second cams,. This optional protrusionprovides an additional point of contact between the safety blockand the takedown actuation lever, which is retained in the receiver(shown in) at the rounded ends of the lever shaft. The trigger pinextends between the trigger bodyand a forward portion of the safety block. A trigger spring guidepermits the proximal end of the trigger springto pivot against the trigger bodyand reduce buckling when the trigger is rotated about the trigger pin. The takedown actuation leverovercomes the force of the trigger spring, shifting the safety blockrearward, in order to rotate to the takedown position. The trigger bodyis positioned laterally between the first armand second armof the safety block. The trigger pinextends laterally through the triggerand the safety block. In the assembled state, ends of the trigger pinengage sidewalls of the receiver. The sear leverengages the trigger bodyand extends rearwardly to the sear (not shown).

illustrates a rear perspective view of the takedown actuation lever, in accordance with an embodiment of the present disclosure. The lever wingconnects to and extends rearward from an end of the lever shaft. The first camand second camextend radially outward from the lever shaft. As noted above, the first camincludes a first portionof a first radius and second portionof a second radius. The second camincludes a first portionof a third radius substantially equal to the first radius of the first portionof the first cam. The second camincludes a second portionof a fourth radius that is less than the second radius of the second portionof the first cam. The fourth radius can be selected to provide clearance between the second camand the safety blockfor installation and removal of the takedown actuation lever. The takedown actuation leveralso includes a lever bodythat extends away from the lever shaft. In this example, the lever bodyhas a block shape or cuboid geometry with a rear face. In this example, the lever bodyextends from the lever shaftin an opposite direction of the second portionof the first cam. In this example, the lever bodyis also oriented generally orthogonal (e.g., vertical) to the lever wing(e.g., horizontal). In the firing position, the rear faceof the lever bodyabuts the receiver, defining a hard stop for the takedown actuation leverthat prevents further rotation. This hard stop enables the takedown actuation leverto be used as a thumb rest in the firing position.

illustrates a front perspective view showing the receiverwith a barrelpinned in place, and with the takedown actuation leverin the firing position. The rear face(not visible; shown in) of the lever bodyabuts the receiver, preventing rotation of the lever wingdownward (e.g., clockwise as viewed looking at the left side of the handgun). The first cam, second cam, and lever shaftare also shown.

illustrates a side view showing components of the receiver, takedown lever assembly, and trigger assemblywith the takedown actuation leverin the takedown position and the triggerat rest, in accordance with an embodiment of the present disclosure. In the takedown position, the lever wingextends upward and the second portionof the cam contacts the frontof the safety block. Due to the increased radius of the second portionof the cam, the safety blockis shifted rearwardly as evidenced by the trigger pinoccupying a forward portion of the elongated pin opening. Note also that the upper portionof the safety blockabuts the trigger body. Further note that ends of the arms,of the safety blockoccupy the magazine welland interfere with the magazine, which is shown in broken lines for reference. With the takedown actuation leverin the takedown position, the triggeris blocked from rotation (i.e., being pulled) due to the upper portionof the safety blockabutting or nearly abutting the trigger body. A magazineis also blocked from being installed in the magazine well, due to interference with the safety block.

illustrates a side view showing components of the takedown lever assembly, trigger assembly, and part of a magazine. Here, the takedown actuation leverhas been rotated counterclockwise to the takedown position with the lever wingrotating upward and forward. In this position, the triggeris at rest and is blocked by the upper portionof the safety blockfrom rotating. The second portionof the camabuts the frontof the safety block, causing the safety blockto move rearwardly into the magazine welland the upper portionof the safety blockto move against the trigger body. Part of a magazineis shown for reference to show the interference between the safety blockand the magazine, but the magazinewould not be able to occupy the magazine wellwith the takedown actuation leverin the takedown position.

illustrates a top, side, and rear perspective view of the takedown lever assemblyand trigger assemblywith the takedown actuation leverhaving been rotated counterclockwise about 90° to the takedown position, in accordance with an embodiment of the present disclosure. In this position, the lever wingextends upward from the lever shaft. The second portionof the camhas pivoted with the lever wingto contact the frontof the safety block. In doing so, the first portionof the cam, which has a smaller radius, now faces upward and is not in contact with the safety block. The larger radius of the second portion, and hence greater distance from the lever shaftto the safety block, causes the safety blockto shift rearward so that the first armand second armextend into the magazine well(shown, e.g., in) and the upper portionof the safety lever is against the trigger body. In the rearward or blocking position of the safety block, the trigger pinoccupies a forward portion of the elongated pin opening. In this position, the safety blockinterferes with installation of a magazineand blocks the triggerfrom pivoting.

illustrates a top plan view of the takedown lever assemblyand trigger assemblywith the takedown actuation leverin the takedown position as also shown in. The first camcontacts the frontof the safety blockand the upper portionof the safety blockabuts the trigger body. Thus, the safety blockblocks the triggerfrom rotating about the trigger pin. Note that the second camis spaced axially from the safety blockand protrusionis also spaced axially by the same amount from the lever shaft. In the event that the takedown actuation leveris removed from the receiver, for example, it can be pulled laterally through the receiverwith the second camclearing the protrusionon the safety block. Sear leverand trigger spring guideare also shown.

As discussed above with reference to, a takedown actuation levercan rotate counterclockwise from the firing position to the takedown position as viewed looking at the left side of the handgun. As such the lever wingcan be used as a thumb rest during use of the handgun without inadvertently rotating the lever to the takedown position.

The takedown actuation levercan be part of a takedown lever assembly. When rotated to the takedown position, a camon the lever shaftis configured to move a safety blockrearwardly. In doing so, part of the safety blockextends into the magazine wellto prevent the user from installing and seating a magazine into the gun. Similarly, when a magazine is present in the magazine well, the user cannot rotate the takedown actuation leverto the takedown position due to the safety block contacting the magazine. Also, rotating the takedown actuation leverto the takedown position moves the safety blockinto contact with the trigger body, blocking the triggerfrom rotating about the trigger pin. In the firing position, a bodyof the takedown actuation leverabuts the receiver, providing a hard stop that prevents further rotation of the takedown actuation leverand enables the lever wingto be used as a thumb rest when firing the handgun.

Embodiments of the takedown lever assemblyare discussed above in the context of a takedown actuation leverthat rotates counterclockwise about 90° from the firing position to the takedown position. For example, the lever wing rotates from a horizontal position where it extends rearward from the lever shaft to a generally vertical position where it extends upward from the lever shaft. It is contemplated within the scope of this disclosure that the takedown actuation levercan rotate in the opposite direction. The takedown lever assemblyis also discussed above with reference to a safety blockthat has a front portion extending laterally between and connecting arms,that extending rearwardly along opposite sides of the trigger body. It is contemplated within the scope of the present disclosure that the safety blockcould have the shape of a bar or lever, along with any necessary tabs or protrusions, as will be appreciated. Numerous variations and embodiments will be apparent in light of the present disclosure.

As will be appreciated in light of this disclosure, embodiments of takedown lever assemblydescribed herein are not limited to use with hammer-fired handguns and may be utilized with striker-fired handguns and other host firearms. In addition, embodiments of a trigger shoe, as variously disclosed herein, can be used with handguns and long guns, including pistols, rifles, and shotguns.

Components of takedown assembly may be constructed from any suitable materials as will be apparent in light of this disclosure. For example, some embodiments of takedown lever, safety block, and trigger shoe can be constructed from steel, polymers, composites, aluminum, or other materials. More generally, components of takedown assembly and trigger shoe can be constructed from any suitable material which is compliant, for example, with United States Defense Standard MIL-W-13855 (Weapons: Small Arms and Aircraft Armament Subsystems, General Specification For).

Referring now to, a side view illustrates a trigger assemblythat includes a trigger bodyand a trigger shoethat can be removably attached to the trigger body, in accordance with an embodiment of the present disclosure. The trigger bodyincludes a lower portion(shown in broken lines) and an upper portion. The trigger bodydefines a pin openingsized to receive a trigger pin therethrough (e.g., trigger pin). The trigger bodycan pivot about the trigger pin when manipulated by the user. The trigger bodymay further define a trigger bar openingfor a trigger bar.

The trigger shoeattaches removably over the lower portionof the trigger body. The trigger shoecan be installed over the front of the trigger bodyand secured using a snap fit. For example, the trigger shoeincludes tabs that overlap a rear edge of the trigger bodywhen the trigger shoeis installed. The trigger shoeincludes a user surfaceand shoe side panelsextending rearward from the user surface. The user surfacecan be flat or arcuate and is configured for the user to manipulate the trigger.

illustrate a front perspective view, a side view, and a rear perspective view, respectively, of a trigger body, in accordance with one embodiment. The trigger body typically is made of metal, but it can also be made of rigid plastic (e.g., a reinforced polymer) or other suitable materials. The trigger bodyincludes a pair of sidewalls or side panelshaving a generally upright orientation and positioned in a parallel, spaced-apart relationship. The side panelsare connected by rear portionextending between each side panel. A lower end portion of each side paneltapers to a point. In some embodiments, each side paneldefines a notch. The notchcan be used as an attachment point for catchesof the trigger shoe.

illustrate rear perspective views of a trigger shoe, in accordance with an embodiment of the present disclosure. In this example, the trigger shoeincludes a user surfacethat is straight and generally planar along a majority portion. A side view of the trigger shoeis also shown in. Shoe side portionsextend rearward from the user surfacein a spaced-apart, parallel relationship. One or both of the shoe side portionsincludes one or more catchthat extends transversely (e.g., at 90°) from the rear of the shoe side portiontoward the opposite shoe side portion. Each catchcan be shaped as a lip, block, hook, or other shape that engages a corresponding portion of the rear faceof a side panelof the trigger body. In some embodiments, the trigger shoeincludes a bodythat extends rearward from a back side of the user surfacebetween the shoe side portions. The bodyis sized and configured to be received between the side panelsof the trigger body. Optionally, a top of the trigger shoedefines a recessfor the trigger pin. In combination, the recesses, body, and catches, the trigger shoecan be seated and securely retained on the trigger body.

illustrate a trigger shoein accordance with another embodiment. In this example, the user surfaceis curved along its length and laterally across the surface. Similar to the trigger shoe discussed above, this example includes catches, shoe side portions, body, and recesses.

To install the trigger shoeon the trigger body, the shoe side panelscan be spread apart slightly to slide the catchesover the side panelsof the trigger body. After moving the trigger shoeis moved rearward onto the trigger bodyso that the catchespass the rear face, the resilient force of the trigger shoereturns the shoe side portionsto their previous shape with the catches overlapping the rear faceof the trigger body(e.g., a snap fit).

The following examples pertain to embodiments of the present disclosure, from which numerous permutations and configurations will be apparent.

Example 1 is a takedown lever assembly for a semiautomatic handgun that includes a receiver, a slide displaceable along a top of the receiver, a grip portion defining a magazine well, and a fire control group that includes a sear operatively connected to a trigger. The takedown lever assembly comprises a takedown actuation lever operable between a firing position and a takedown position, where in the takedown position the takedown actuation lever permits removal of the slide from the frame; and a safety block operatively coupled to the takedown actuation lever, where moving the takedown actuation lever from the firing position to the takedown position moves the safety block rearward, thereby blocking the trigger from rotating to a pulled trigger position.

Example 2 includes the subject matter of Example 1, where the safety block moves into contact with the trigger in response to moving the takedown actuation lever to the takedown position.
