Well since I have had my c9 I had only fired 20 rounds through it. There is a range about a 1/2 mile from me. So a few friends and myself decided to go to the range. We put 1000 , YEP you read it right, 1000 rounds through it. Not the first problem. No jams, no feed probs at all. Some were rapid fire and some other were double tap.We put 5 mags of 10 rnds through it as fast as we could fire it and swap mags. My hands are tired and my arms are sore as they can be. Not counting spending 6 hours at the range. I was impressed with her. I have heard other folk talk bad about this piece because of the price. II have heard everything you can think of. The funny part is, my old Ruger p85 MK.2 was there ,(sold it to a friend long ago). The p85 had continual feed issues. The HP only has one problem after all the heavy use today. It seems the slide is a little noisy now. It may have been that way and I never noticed it. Should I send it back or not. So far it is not causing any problems. I cleaned it but didn't take the slide off or anything. Sorry for long post.
