I've put a couple hundred rounds through mine no problems what so ever normal and high velocity ammo. One thing I did do is when I first got it I cleaned it and put some medium loc-tite on the takedown screw. The only problem I had was out of the box it shot high and I had to adjust the sight for that. It is far more accurate than my TX 22 or my Mark III was that I sold. It's good you found a gun that you like.
