The KelTec PR-5.7 is an exceptionally lightweight and slim 5.7x28mm semi-automatic pistol built around an innovative rotary-barrel operating system and a unique top-loading design. This compact 10+1 configuration combines a 4.64-inch stainless steel barrel, optic-ready slide, accessory rail, and lightweight polymer frame for shooters looking for a highly portable 5.7mm pistol for range use, recreational shooting, and lawful defensive applications.
Rather than using a conventional detachable box magazine, the PR-5.7 uses KelTec's distinctive internal loading system to maintain an extremely thin profile. Its locked-breech rotary barrel helps manage the high-pressure 5.7x28mm cartridge while contributing to the pistol's light weight and compact dimensions. The black oxide steel slide features front and rear serrations for positive manipulation, while the optic-ready configuration allows installation of a compatible micro red-dot sight using the appropriate mounting system.
