The Kel-Tec KP50 Pistol (brand part no. KP50TAN) chambers the flat-shooting 5.7x28mm cartridge in a compact, tan-finished semi-auto platform built around a massive 50-round magazine, giving shooters far more capacity than a typical pistol-caliber handgun. Its 9.6-inch threaded barrel handles a suppressor or compensator without giving up much in overall size, and the optics-ready slide lets shooters mount a red dot straight from the factory. Kel-Tec designed the KP50 for range enthusiasts and home-defense shooters who want high capacity and low recoil in one package, backed by a manual safety for an added layer of control. It’s a genuinely different take on the pistol-caliber platform from a manufacturer known for unconventional designs.
