Kel-Tec’s new-for-2025 PR57, a semi-automatic, hammer-fired pistol chambered for the 5.7x28 mm FN cartridge is turning heads throughout the personal-defense firearm world. Why? The pistol feeds from an internal 20-round box magazine fed by stripper clips, and there is no detachable box magazine. Outfitted with a 4.6” barrel, the gun weighs just under 14 ozs. unloaded, and measures about 7” long, 5” high and less than an inch wide. Two 10-round stripper clips are included with each pistol. The PR57 is also capable of mounting a red-dot optic. Check out the video from our friends at American Rifleman. For more, visit keltecweapons.com.
