The PTR 91 K3P PDW Pistol (brand part no. AC100008) brings PTR’s roller-delayed 91-pattern action to a compact, .308 Win-chambered pistol platform. A 12.5-inch barrel threaded 5/8×24 accepts standard muzzle devices and suppressors, while the M-LOK handguard, sling mount endcap, and 7.5-inch top rail give shooters a solid foundation for lights, optics, and slings. Built for shooters who want the stopping power of .308 Winchester in a shorter, more maneuverable package than a full-length rifle, this pistol ships with a single 20-round magazine. It’s a standout, higher-caliber option in the AR pistols lineup from PTR.
