When I got my gun, I think I put 50 rounds through it the first time. I thought the "kick" was a little more than my P3AT but not too bad. Over the course of a week or so, and shooting other guns as well, I put over 200 rounds through it. Replaced the spring, blah, blah, blah...
The gun functions like it should and as other have said, the recoil is no where near as bad as some people believe. I like the gun, and it performs well for the intended purpose.
