Abstract
A shotgun includes an action that locks the firing pin in a retracted position when the action is not closed. In one embodiment, the firing pin is held in a retracted position without the use of a spring, which may fail over time. In another embodiment, the action includes a bolt slide that is configured to hold the firing pin in the retracted position when the action is open.
Claims20
An autoloading shotgun comprising:
- a firing pin that moves between an extended position and a retracted position;
- and
- a bolt assembly that moves between a forward position where the firing pin is capable of moving to the extended position to allow the shotgun to be fired and a rearward position where the firing pin is held in the retracted position and is unable to move to the extended position;
- a retaining member configured to couple the firing pin to the bolt assembly and move longitudinally with the firing pin relative to the bolt assembly;
- wherein the firing pin moves between the extended position and the retracted position without being biased by a spring.

A shotgun comprising:
- a bolt slide including opposing walls that extend upward;
- a bolt positioned between the opposing walls of the bolt slide;
- and
- a firing pin that extends through the bolt and moves between an extended position and a retracted position;
- wherein the bolt moves between a forward position where the firing pin is capable of moving to the extended position to allow the shotgun to be fired and a rearward position where the bolt slide holds the firing pin in the retracted position and prevents the firing pin from moving to the extended position.
2 more elements
A shotgun comprising:
- a bolt and a bolt slide;
- a firing pin that extends through the bolt and moves between an extended position and a retracted position;
- and
- a retaining member positioned transverse to the firing pin and configured to move with the firing pin as the firing pin moves between the extended position and the retracted position;
- wherein the bolt moves between a forward position where the firing pin is capable of moving to the extended position to allow the shotgun to be fired and a rearward position where the bolt slide holds the firing pin in the retracted position and prevents the firing pin from moving to the extended position.
