I'd like to tap into the collective expertise of this boards membership, if I may. I have a P3AT I bought new about a year ago. I finally got it to the range a month ago. It worked ok for several rounds, then failed to fire. The previous round had fired, the gun ejected and re-loaded normally, but the hammer did not return to its normal position and the trigger was "free-wheeling." Pulling and releasing the slide cleared the problem, but it occurred again a few rounds later. Any ideas?
