Purchased a Walther PPQ ( Police Pistol Quick Defense) today and shot 150 rounds of 124 grain 9mm rounds through it. No malfunctions. It is the first Walther I have owned so I can't compare it to the PPS or P99 or other Walther pistols. It feels good in the hand and shoots accurately. It has ambidextrous slide locks and magazine ejector. Holds a 15 round magazine. It came with 2 magazines. The best feature of this pistol is the trigger. The trigger may be the best trigger I've experienced; smooth short travel with a clean crisp break and a very very short reset.
