I have two PPQ's. One's a 9mm and the other is a 40S&W. Both are very accurate, especially the 40S&W. Unfortunately, it's not 100% reliable. Walther's customer service is horrible. They blamed a variety of ammunition that runs 100% in many other 40S&W chambered pistols that I have while ignoring the chatter marks on the underside of the barrel and the brass shavings that keep appearing.
