A takedown lever assembly for a striker-fired handgun. The takedown lever assembly includes a takedown actuation lever operable between a firing position and a takedown position, and a safety bar operatively coupled to the takedown actuation lever. The safety bar moves longitudinally along the frame in response to moving the takedown actuation lever from the firing position to the takedown position, thereby causing the sear to disengage from the striker.

A crossbow includes a supporting body, a hook unit, a bow and a triggering device. The supporting body includes an elongated portion and a butt detachably connected to the elongated portion. The hook unit is provided on the butt. The bow is provided on the supporting body. The triggering device is located in the elongated portion to control the bow. The triggering device includes a shell, a trigger unit located in the shell, and a security unit movable between a locking position and an unlocking position. The security unit abuts against the trigger unit in the locking position to restrain the trigger unit. The hook unit moves the security unit to the unlocking position when the butt is connected to the elongated portion. The security unit moves to the locking position when the butt is moved from the elongated portion.

The present invention concerns a firearm comprising at least one frame and a barrel group comprising at least one barrel, the barrel group being mounted in a sliding manner with respect to the frame, wherein the frame houses at least one trigger device configured to trigger the firing of an ammunition, a safety device configured to act on the trigger device so as to selectively disengage it, and a closing device configured to act between the frame and the barrel group so as to prevent the barrel group from tilting with respect to the frame, and is characterized in that it comprises an actuation element configured to selectively activate the safety device and the closing device.
