A handgun, including a safety lever for disengaging a sear, the safety lever located under a slide of the handgun and extending along a longitudinal axis within a body of the handgun, wherein the safety lever includes a) a sear switch located external to the body of the handgun, and is configured to be positioned by a user in one of at least two positions along the longitudinal axis of the handgun and configured to move the safety lever with the sear switch to an elected position; (b) a sear tab at a rear end of the safety lever near a sear of the handgun, wherein when the sear switch is in a first position the sear tab does not interfere with the action of the sear and when in a second position the sear tab causes the sear to tilt so that the sear is disengaged and cannot come in contact with a striker of the handgun to fire a bullet.

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.

A firearm inhibiting device and method of using the same is disclosed which will only mount onto the firearm if the firing chamber is empty of ammunition (a live cartridge). Further inhibiting, for handguns the device prevents operation of the gun's action mechanism. Further inhibiting, for long-guns the device prevents a live cartridge from entering the firing chamber. The empty chamber indication is unique in that it will indicate an empty firing chamber while the action is prevented from operation and in the battery position.

Apparatus and associated methods relate to a firearm lock configured to release a self-hardening interlock fluid into a firing chamber of a firearm in response to a predetermined force. In an illustrative example, the firearm lock may include an engagement module configured to releasably couple to a firing chamber of the firearm. In a locked mode, for example, the engagement module may prevent the firearm from firing. The firearm lock may include, for example, a tamper interlock module containing interlock material (IM) in a fluid state. When a predetermined force is applied to the tamper interlock module, for example, the IM may be dispensed from the cavity into the firing chamber and the IM may at least partially transition into a solid state such that the IM prevents the firearm from firing. Various embodiments may advantageously disable a locked firearm in response to tampering with the lock.

A firearm with dual-acting safety mechanism includes a hammer, sear operable to hold the hammer in a cocked position, and trigger mechanism including a trigger and trigger bar which collectively operates to rotate the sear to release the hammer. The safety mechanism includes a safety mode selector or actuator cooperating with a secondary safety link. In one arrangement, linearly moving the selector actuates and rotates the safety link which simultaneously both blocks the hammer and displaces the trigger bar such that the sear can no longer be actuated via a trigger pull.
