 The greatest disappointment I had was from a Smith & Wesson Performance Center Model 19 carry comp. K-Frame Revolver with a 3 inch barrel. The features are great. It has a compensator, tritium front dot, a adjustable rear sight, rosewood grips, beautiful looking revolver, but what happened was the trigger lock. This revolver clearly had a problem. Something that was foreign to me, the trigger locked up, I've never had this happen on any revolvers that I owned. I was so excited to get this revolver. So what happened was I contacted Smith & Wesson and said, Hey, I've got this problem here. It was all through email. I was totally ghosted. But the way this performed, for a performance center, it was a performance let down that I could not wait to get rid of it.
