I had my P99 QA .40 at the range and was doing rapid fire double tap drills. I have put only about 350 rounds through the gun, as I got it new this month. One time the trigger failed to reset. The gun fired normally, but the trigger felt "funny". I was shooting as fast as possible when this happened. A round had been loaded in the chamber as normal, but the trigger was de-cocked and usless. I had to pull the slide back to re-set the striker and set the trigger. Is this a common problem with the QA? Is it caused somehow by short stroking the trigger in rapid fire? Clearly this is a big problem if it is a common thing. Thanks for the input peeps.
