The KelTec KP50 is a compact 5.7x28mm semi-automatic pistol platform designed as the next evolution of KelTec’s high-capacity P50 concept, using FN P90-style 50 round magazines in a more refined PDW-style configuration. It features a 9.6" threaded barrel, full-length Picatinny optics rail interrupted for top ejection, rear Picatinny accessory rail on the base pistol, drop-free magazine system, polymer construction & optional braced, SBR, Defender and select-fire MP50 variants. Designed for recreational shooting, defensive-style training, compact PDW applications & 5.7 enthusiasts who want maximum onboard capacity, the KP50 delivers an unusually lightweight, compact platform with substantial magazine capacity & suppressor-ready capability. KelTec has built its reputation around unconventional firearm designs that emphasize lightweight construction, high capacity & innovative packaging and the KP50 follows that same philosophy while improving speed, ergonomics & accessory support over the earlier P50 format. The 9.6" barrel helps the 5.7x28mm cartridge maintain strong velocity, while the 1/2x28 threaded muzzle, A2-style flash hider, 1:7 twist rate, folding brace or stock options & 100-round Jungle Clip configuration expand its usefulness for range & PDW-style setups. Early coverage highlights the KP50 as a more practical, refined version of the P50 concept, with the Defender package adding a Vortex Crossfire optic, Magpul MBUS sights, speedloader & hard case for a complete factory configuration. Overall, the KP50 is a distinctive high-capacity 5.7 platform built for shooters who value compact size, low recoil & KelTec’s signature engineering approach.
