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

1 . A trigger for a firearm, comprising:
a trigger body defining a pivot pin opening and having a lower portion extending below the pivot pin opening and an upper portion above the pivot pin opening; and a trigger shoe configured to be removably attached to the lower portion of the trigger body, wherein the trigger shoe has a front wall defining an user interface and a rear surface configured to matingly engage a front of the lower portion of the trigger body.

2 . The trigger of claim 1 , wherein the trigger shoe is configured to be removably installed via a snap fit in a rearward direction over the front of the lower portion of the trigger body.

3 . The trigger of claim 2 , wherein part of the trigger shoe wraps around a rear surface of the lower portion of the trigger body in an installed state.

4 . The trigger of claim 3 , wherein the lower portion of the trigger body includes a pair of walls oriented in a spaced-apart configuration, and where a front surface of each of the pair of walls engages the rear surface of the trigger shoe in an installed state.

5 . The trigger of claim 4 , wherein part of the trigger shoe is received between the pair of walls in the installed state.

6 . The trigger of claim 1 , wherein the lower portion of the trigger body includes a pair of walls oriented in a spaced-apart configuration.

7 . The trigger of claim 6 , wherein the trigger shoe includes sidewalls each having a catch surfaces that engages a rear surface of each of the pair of walls.

8 . The trigger of claim 1 , wherein the user interface has a linear profile as viewed from a side of the trigger shoe.

9 . The trigger of claim 1 , wherein the trigger shoe is made of a polymeric material.

10 . A firearm comprising the trigger of claim 1 .

11 . The firearm of claim 10 , wherein the firearm is a semiautomatic handgun.

12 . The firearm of claim 10 , wherein the firearm is a rifle.

13 . A trigger shoe for a firearm trigger having a front surface and sidewalls that extend rearward from the front surface to a rear surface, the trigger shoe comprising:
a front wall defining a front user interface for firing the firearm; spaced-apart sidewalls extending rearward from the front wall in a spaced-apart configuration; and one or more catch surfaces configured and arranged to engage the firearm trigger to retain the trigger shoe on the firearm trigger; wherein the trigger shoe is configured to be removably installed with a snap fit over the front surface of the firearm trigger.

14 . The trigger shoe of claim 13 , wherein the firearm trigger defines a trigger pin opening for a trigger pin and an upper end of the trigger shoe is configured to engage the trigger pin in an installed state.

15 . The trigger shoe of claim 13 , wherein the one or more catch surfaces are configured to engage the rear surface of the trigger.

16 . The trigger shoe of claim 15 , wherein each of the one or more catch surfaces is configured as a lateral protrusion.

17 . The trigger shoe of claim 13 , wherein the trigger shoe is made of a polymeric material.

18 . The trigger shoe of claim 13 , wherein the trigger shoe is configured to matingly engage the front surface of the firearm trigger.

19 . The trigger shoe of claim 13 , wherein a rear surface of the front wall of the trigger shoe includes a rearward protrusion configured to be received in a recess or opening of the firearm trigger.

20 . The trigger shoe of claim 13 , wherein the front user interface is curved.
