After about 2 months with little use the trigger set failed. The gun was firing, then it would not release the hammer when trigger was pulled but when you released the trigger to reset, it would fire. This went for a few more shots then it completely stop working. I took the trigger set out to see what was causing the problem. I small metal part fell out. Seems the hammer release was broken. I ordered another gun and will see if this is an ongoing issue with these guns. It was fun using it even tho collecting the shells was not. The PPS shell catcher cause the gun to jam a lot so I took it off and stop using it. The gun I got originally was the one that came with the plastic shells.
