The gun looked solid for the money not bad I felt optimistic, then I started trying to break it in I shot heavy high brass loads an entire case of shells and it still wouldn't cycle every shot. I ended up sending it back to CZ to have it tuned they sent it back with assurance that it would cycle anything now. I started shooting again the gun performed well, one thing which isn't a huge deal but this gun has to be completely broke down every time you shoot it and cleaned thoroughly if you do that it cycles very well. I was pleased till the gun started malfunctioning again it would shoot one time and wouldn't cycle and when trying to manually work the action it was very difficult this is my wife's gun and she couldn't do it and I had trouble myself. I broke the gun down and found that the piston o ring had broken in half I called CZ they said that they have had a lot of trouble with that and they sent another out. I have shot the gun a few times since then and haven't had any issues but it was a troublesome trip to get here. I would not go with this gun if I had it to do over again I would have spent a little more and saved myself some hassle.
