The Walther PPQ is a German, short recoil-operated pistol introduced at the Shot Show in 2011 by Carl Walther GmbH. Fed from a 15-round magazine, it shoots 9x19mm Parabellum cartridges, with an effective range of 50 m and a muzzle velocity of 408 m/s. Compact and ergonomic, it feels comfortable in the hand as it has an ambidextrous slide lock and magazine release, which is a lever that is pushed down and located right beside the lower part of the trigger guard. The Walther PPQ has a polymer frame with a steel slide, a replaceable backstrap, and 3-dot iron sights, with the rear ones being adjustable. Like the Glock, the safety mechanism is on the trigger, which is light, crisp and very short reset. It is used by German police forces and special units.
