A semiautomatic handgun includes various unique features to facilitate rapid, accurate shooting. Some examples of the handgun include a more compact recoil spring system, locating the recoil spring around the barrel while permitting rearward movement of the barrel in conjunction with the slide. Other examples include an automatic magazine release for releasing the magazine upon the discharge of the last cartridge in the magazine. Still other examples include a grooved or roughened top slide surface for facilitating slide manipulation with one hand. Further examples include auxiliary sight systems to facilitate determining the proper distance by which to lead a moving target. Other examples include a takedown tool stored within the handgun.

An internal firearm locking mechanism includes a block that fits within the action of a firearm, and a lock that is removably secured to the block and passes into the chamber of the firearm to resist insertion of a cartridge as well as removal of the block. An installation/removal tool is used to install and remove the internal firearm locking mechanism.
