The Kel-Tec PR-57 is an innovative ultra-lightweight pistol chambered in the high-velocity 5.7x28mm cartridge, designed to deliver impressive capacity, low recoil, and streamlined everyday carry performance. Combining modern engineering with an unconventional loading system, the PR-57 offers a sleek profile and reduced bulk while maintaining excellent reliability and shootability.
One of the most unique aspects of the PR-57 is its revolutionary magazine-less internal feed system. Instead of relying on a traditional detachable box magazine, the pistol uses an internal top-loading design that allows rounds to be inserted directly into the grip. Shooters can manually load individual rounds or quickly charge the firearm using the included 10-round stripper clips. This system significantly reduces grip width and overall weight while still providing an impressive 20+1 round capacity. The innovative design also creates an exceptionally slim and compact profile for comfortable carry and handling.
The PR-57 is engineered to be extremely lightweight, weighing under 14 ounces unloaded. Kel-Tec achieves this through advanced materials, minimalist engineering, and a unique rotary barrel system that helps reduce mass without sacrificing durability. The lightweight construction makes the pistol easy to carry all day while also minimizing shooter fatigue during extended range sessions.
Chambered in 5.7x28mm, the PR-57 delivers high velocity, flat trajectory performance, and reduced recoil compared to many traditional defensive calibers. The cartridge is known for its fast-moving lightweight projectiles, excellent controllability, and increased magazine capacity potential. Combined with the PR-57’s low recoil impulse and ergonomic design, shooters benefit from quick follow-up shots and easy handling.
Additional features include an optics-ready slide for mounting compatible red dots, a crisp trigger pull, an integrated accessory rail, and a modern polymer frame designed for durability and comfort. Kel-Tec’s simplified operating system focuses on practical reliability while maintaining a compact footprint ideal for everyday use.
