The PMR-30 is a light weight, full size pistol chambered for the flat shooting .22Magnum cartridge (.22WMR). The PMR-30 operates on a unique hybrid blowback/locked-breech system. This operation system allows for the use of a wide variety of ammunition as it seamlessly adjusts between locked breach and blowback operation, depending on the pressure of the cartridge. It uses a double stack magazine of a new design that holds 30 rounds and fits completely in the grip of the pistol.

The trigger is a crisp single action with an over travel stop. The manual safety is a thumb activated ambidextrous safety lever (up for SAFE, down for FIRE). The slide locks back after the last shot and a manual slide lock lever is also provided. The light, crisp trigger pull and fiber optic sights make the PMR-30 ideal for target shooting and hunting small game. Slide and barrel are 4140 steel, frame is 7075 aluminum. Grip, slide cover, trigger, mag release, and safety levers are glass reinforced Nylon (Zytel), much like other Kel-Tec Pistols. Magazine is Also Zytel and holds 30 rounds, with round count ports. Other features include: dual opposing extractors for reliability, heel magazine release to aid in magazine retention, dovetailed aluminum front sight, Picatinny accessory rail under the barrel, Urethane recoil buffer, captive coaxial recoil springs. The barrel is fluted for light weight and effective heat dissipation. PMR30 disassembles for cleaning by removal of a single pin.  This model features a Midnight Bronze Cerakote frame and blued slide.
