Kel-Tec KP50 Defender 5.7x28mm Pistol, 9.6" Barrel, 100 Capacity w/ Vortex Crossfire Red Dot Optic, Magpul MBUS Backup Sights & Hard Case Overview: The Kel-Tec KP50 Defender is a semi-auto tactical pistol chambered in 5.7x28mm, built for extreme magazine capacity in a compact, controllable format. Featuring a redesigned bottom-insert, drop-free magazine system, the KP50 eliminates the original P50's top-hinged reload process, enabling faster, more intuitive magazine changes while retaining the platform's signature 50-round capacity per magazine. The Defender package pairs this action with a factory-installed Vortex Crossfire red dot and Magpul MBUS backup sights, delivering a ready-to-run setup straight from Kel-Tec. Key Features: Drop-Free Magazine System: Bottom-insert design replaces the original top-hinged reload for faster, more intuitive magazine changes. 100 Round Capacity: Optional Jungle Clip configuration pairs two 50-round magazines back-to-back for 100 rounds total.
