The Kel-Tec PR57 rewrites the 5.7×28 playbook with a striker-fired, semi-auto design that packs 20+1 rounds in an internal storage system—no traditional detachable magazine required. The result is a slimmer, snag-resistant profile that carries light, points fast, and keeps the focus on performance.

A tan polymer frame paired with a black slide gives it a modern two-tone look, while the optics-ready slide streamlines red-dot mounting for rapid target acquisition. Built for reliability and easy handling, the PR57 makes the most of the flat-shooting 5.7×28 cartridge in a compact, innovative package.
