Ruger-57™ Features

The KelTec PR-57 presents a unique challenge for a zombie apocalypse scenario due to its specialized 5.7x28mm ammunition and internal magazine design. While the pistol itself is not inherently bad, its loading and reloading procedures differ significantly from conventional firearms. The PR-57 features dual guide rods and a rotating barrel for locking, offering low recoil and high penetration with its 5.7 cartridge. Reloading mid-fight requires dropping rounds directly into the internal magazine well rather than swapping magazines.
