Kel-­Tec's PMR-30 is a .22 Win. Mag. Rimfire (WMR) pistol that's been in high demand and low-volume production (due to design improvements) since it was unveiled in 2011. The big takeaways are that the PMR-30 is a semiauto that reliably chambers .22 Magnum and feeds from a 30-­round, double-­stack magazine.  The hybrid blowback action combines elements of both locked-breech and blowback designs subject to pressure levels. With higher-­pressure loads, the barrel moves slightly rearward with the slide as it would with a traditional locked-breech design. When firing lower-­pressure loads, the PMR-­30 acts akin to blowback firearms. This versatility means that the PMR-30 will cycle the wide range of .22 WMR ammo available. The system is deceptively simple. A pair of beefy extractors holding the cartridge rim at the 3 and 9 o'clock then clears the chamber and readies again.
