Abstract

A handgun trigger has a trigger body configured for pivotable or rotatable movement when installed in a handgun. A trigger shoe is removably attached or attachable to the trigger body and defines a user interface for firing the handgun. The trigger shoe can be made of polymeric material and can be attached to the trigger body using a snap fit. For example, the trigger shoe snaps over rear-facing surfaces of the trigger body when installed. Also disclosed is a takedown lever assembly for a semiautomatic handgun, where the takedown actuation lever operable between a firing position and a takedown position. In the takedown position the takedown actuation lever permits removal of the slide from the frame. In the takedown position the trigger is blocked from rotating to the pulled trigger position.

First claim

What is claimed is:

1. 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 trigger pivotable between a resting position and a pulled trigger position, the takedown lever assembly comprising:
a takedown actuation lever operable between a firing position and a takedown position, wherein in the takedown position the takedown actuation lever permits removal of the slide from the frame, and wherein moving the takedown actuation lever from the firing position to the takedown position blocks the trigger from rotating to the pulled trigger position.

2. The takedown lever assembly of claim 1 , further comprising a safety block between the takedown actuation lever and the trigger, wherein moving the takedown actuation lever to the takedown position moves the safety block moves into contact with the trigger.

3. The takedown lever assembly of claim 2 , wherein the safety block abuts an upper portion of the trigger when the takedown actuation lever is in the takedown position.

4. The takedown lever assembly of claim 2 , wherein the takedown actuation lever comprises:
a lever shaft extending crosswise through the receiver; and
a cam extending radially outward from the lever shaft, the cam having a first cam portion with a first radius and a second cam portion with a second radius greater than the first radius, wherein the first cam portion contacts a front of the safety block when the takedown actuation lever is in the firing position and the second cam portion contacts the front of the safety block when the takedown actuation lever is in the takedown position.

5. The takedown lever assembly of claim 4 , wherein the safety block includes a distal portion extending crosswise to the receiver and at least one arm extending proximally from the distal portion along a side of the trigger, wherein when the takedown actuation lever is in the takedown position, the distal portion abuts an upper portion of the trigger.

6. The takedown lever assembly of claim 5 , wherein the at least one arm includes a first arm and a second arm extending proximally from the distal portion in a spaced-apart, parallel relationship, and wherein the first arm extends along a left side of the trigger and the second arm extends along a right side of the trigger.

7. The takedown lever assembly of claim 5 , wherein a proximal end of the at least one arm extends into the magazine well when the takedown actuation lever is in the takedown position.

8. The takedown lever assembly of claim 2 , wherein part of the safety block extends into the magazine well when the takedown actuation lever is in the takedown position.

9. The takedown lever assembly of claim 2 , wherein the safety block has a lateral protrusion positioned to obstruct trigger rotation when the takedown actuation lever is in the takedown position.

10. The takedown lever assembly of claim 1 , wherein the takedown actuation lever rotates counterclockwise from the shooting position to the takedown position as viewed looking at the left side of the handgun.

11. The takedown lever assembly of claim 1 , wherein the takedown actuation lever includes a lever body configured to abut the receiver of the handgun when the takedown actuation lever is in the firing position.

12. A handgun comprising the takedown lever assembly of claim 1 .
