Hand Gun

In handgun evolution, the semi-automatic pistol emerged after practical revolvers; it uses recoil energy to reload, with gas operation in powerful cartridges like Desert Eagle or blowback for less potent ones. After firing, it cycles, ejects spent casings and chambers a new round, enabling immediate next shots. Terms for semi-automatic pistol include automatic pistol, autopistol, autoloader, self-loading pistol, and selfloader.
