A bolt catch device for firearms, which is connected to a lower housing and includes a linkage portion and a release portion. The linkage portion is connected to the lower housing by a first pivot shaft and has an abutting member. The release portion is connected with the lower housing by a second pivot shaft, and has a pin and a bolt catch. When the user uses the trigger finger to move the bolt catch, the bolt catch performs a rotational displacement movement from a first position with the second pivot shaft as the center, so that the bolt catch is located at the second position. The abutting member performs a rotational displacement movement centered on the first pivot shaft, and the abutting member is away from the bolt, and the bolt moves to complete the feeding of the ammunition.

Pistols have a frame, a firing facility operable to discharge the pistol, a safety device connected to the frame and having a safe condition in which discharge is disabled and an operable condition in which discharge is enabled, an actuator responsive to the presence of a safety-indicating element and operative to control the condition of the safety device such that the safety device is in the safe condition when the safety-indicating element is absent and in the operable condition when the safety-indicating element is present, a selector connected to the frame and operably connected to the safety device, and the selector being movable between an enabled position in which the safety device is operably responsive to the presence and absence of the safety-indicating element, and a disabled position in which the safety device remains in the operable condition irrespective of the presence and absence of the safety-indicating element.

Firearms with combined bolt catch and ejector have a bolt defining a bolt face configured to receive a case head of a cartridge, a bolt catch connected to a frame and movable between a first operational position in which bolt reciprocation forward from the rear position is enabled, and a second restraining position in which a portion of the bolt catch restrains the bolt in the rear position, and the bolt catch having an ejector surface portion positioned clear of the bolt face when the bolt catch is in the first operational position and in registration with a portion of the bolt face when the bolt catch is in the second restraining position such that a case head received by the bolt face strikes the ejector surface portion upon movement of the bolt from the forward to the rearward position when the bolt catch is in the second restraining position.

A bolt stop actuator is disclosed. The actuator may include a lift arm, a first leg extending from a point proximate to an end of the lift bar and generally perpendicular therefrom, a second leg extending in the same direction from the lift bar as the first leg, and a projection extending from the lift bar and configured to contact a follower of an empty magazine when the bolt stop actuator is assembled into a firearm. Neither the first leg, nor the second leg, include apertures positioned distal to the lift arm.
