• The fully machined lower receiver uses the proven Kel-Tec SU16 trigger group, providing a reliable and consistent fire control interface built on a platform with a long service history

Practical Benefits

• The Kel-Tec KP50 Braced Pistol (KP50BLKB) in 5.7x28mm is the most complete, ready-to-shoot configuration in the KP50 lineup, combining a factory brace, two magazines, and the Jungle Clip system so shooters can run 100 rounds before ever needing to reach for a spare mag
• The side-folding brace reduces overall length to 18.6 inches when folded, making the KP50BLKB easy to store, transport in a vehicle, or pack in a range bag without disassembly
• The 5.7x28mm cartridge is a high-velocity, low-mass round with a flat trajectory and manageable energy on target, making the KP50BLKB a practical choice for home defense, range shooting, and small game in jurisdictions where it is legal
• At 4 pounds unloaded, this platform is significantly lighter than comparable high-capacity pistol and carbine formats, reducing fatigue during extended range sessions while remaining stable and easy to handle
• The threaded barrel and factory-installed brace make the KP50BLKB one of the most accessory-ready platforms in its class, readily accepting suppressors, weapon lights, and optics with minimal additional investment
• The Jungle Clip reload is simple and fast, requiring only that the shooter flip the connected magazine pair 180 degrees and reinsert, keeping round count high and hands-on-trigger time maximized during competition stages or training drills
• The ambidextrous safety and non-reciprocating charging handle make the KP50BLKB equally practical for right- and left-handed shooters without any modification or additional parts
