Special Features
The KP50BLK features a completely redesigned bottom-insert, drop-free magazine system that replaces the original P50 top-hinged loading configuration, enabling faster, more natural reloads that mirror conventional pistol and carbine muscle memory
The fully machined lower receiver uses the proven Kel-Tec SU16 fire control group, providing a consistent, reliable trigger interface built on a platform with a long track record in the field
The threaded 9.6 inch barrel with 1/2x28 TPI muzzle threading is optimized for the 5.7x28mm cartridge and accepts a wide range of suppressors and muzzle devices without additional adapters
The rear Picatinny-style rail adapter supports side-folding pistol brace or stock configurations, giving shooters the ability to add stabilization options and tailor the platform to their intended use
The B5 Systems grip is a proven, widely trusted interface known for its ergonomic design and durability, and the AR-compatible grip socket means shooters can swap to any standard AR pistol grip they prefer
The optional Jungle Clip configuration links two 50-round magazines together for 100 rounds of total onboard capacity, a feature unique to this platform in the civilian market
The non-reciprocating charging handle keeps manipulation simple and predictable without requiring the shooter to clear the path of a moving bolt carrier
Practical Benefits
The Kel-Tec KP50 (KP50BLK) in 5.7x28mm is built for high-capacity enthusiasts, range shooters, and collectors who want a compact, lightweight platform that holds more ammunition than nearly any other pistol-format firearm on the market
The 5.7x28mm cartridge is a high-velocity, low-mass round known for its flat trajectory, minimal wind drift, and manageable energy on target, making the KP50BLK an effective choice for home defense, range use, and small to medium game in jurisdictions where it is appropriate
At just 4 pounds unloaded, the KP50BLK is significantly lighter than comparable high-capacity platforms, making it practical for extended range sessions and comfortable to carry in a sling configuration
The bottom-insert magazine system makes reloads intuitive for anyone familiar with standard pistols or carbines, reducing training time and improving performance under pressure
The threaded barrel and Picatinny rear rail make this pistol one of the most accessory-ready platforms in its class, supporting suppressor use, lights, lasers, and brace or stock additions with minimal additional cost or gunsmithing
The folding configuration reduces overall length to 18.6 inches, making storage, transport, and vehicle carry far more practical than the platform's full operating length suggests
The 50-round standard capacity and optional 100-round Jungle Clip make the KP50BLK a standout choice for competition shooters running high-round-count stages and for range enthusiasts who prefer fewer magazine changes during long shooting sessions
The Kel-Tec KP50 (KP50BLK) in 5.7x28mm is a capable tool for high-capacity enthusiasts, range shooters, and serious collectors who want an innovative, lightweight, and fully accessory-ready platform with unmatched onboard ammunition capacity in its class.
