. Like the P22, the PK380 features a slide-mounted, ambidextrous manual hammer-block, non-decocking safety and an external hammer. The magazine release is also ambidextrous using the Walther-style paddle release on the base of the trigger guard. However, unlike other Walthers, there is no slide release lever. Thus, the slide must be pulled rearward and released to chamber the first round. To release the slide with an empty magazine, the magazine must be dropped slightly or completely removed and the slide pulled rearward and released. The slide, barrel, and internal frame are steel, and the grip is polymer

 for reduced weight. Magazines are single-stack design holding 8 rounds giving the gun an 8+1 capacity. Also included is a picatinny-style rail which will accommodate Walther's laser aiming system.

Operation

The PK380 may be fired double action or single action. Unlike the P22, which the PK380 is based on, the PK380 does not operate by blowback

where pressure generated by a firing cartridge is countered by a combination of the inertial weight of the slide assembly and the force of the recoil spring. Instead, the PK380 employs a Browning-type, tilt barrel design. The action will not open until the projectile has left the barrel and the pressures have dropped to safe levels.
