A takedown lever assembly for a semiautomatic handgun includes a receiver, a slide displaceable along a top of the receiver, a grip portion defining a magazine well, and a fire control group that includes a trigger pivotable between a resting position and a pulled trigger position. The takedown lever assembly includes a 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. A safety block is operatively coupled to the takedown actuation lever, wherein moving the takedown actuation lever from the firing position to the takedown position moves the safety block rearward, thereby blocking the trigger from rotating to the pulled trigger position. In some embodiments, the takedown lever rotates counterclockwise from the firing position to the takedown position as viewed looking at a left side of the handgun.

A training pistol and method of providing the same having fixedly and adjustably removable base extensions to emulate the feel of a corresponding live fire pistol, a trigger mechanism configured to be fit in a compact pistol to provide a large number and sophistication of sear surfaces and biasing members such as helical springs and lasers into a compact pistol to provide training for an end user such as concealed carry holder or law enforcement personnel.

A selective fire firearm may be provided having a fully automatic open bolt and a semi-automatic closed bolt mode of operation. The firearm may include a trigger group having a trigger prop that ensures that, when the trigger is released in the fully automatic open bolt mode, the bolt carrier stops in an open bolt position held by an open bolt sear. The trigger prop may include a foot that, following a first trigger pull in the fully automatic open bolt mode, slides under and props a rear end of the trigger in a position that allows the open bolt sear to catch the bolt carrier when the trigger is released and propped but prevents the trigger sear from engaging the hammer.

A buttstock of a small arm includes a front connection area for a positive connection to a receiver. In order to permit increased cartridge capacity, a trigger unit with a trigger latch and a transfer element extending forward for connection of the trigger latch to a trigger mechanism arranged in the receiver is positioned on the buttstock.
