I have one and I LOVE it. It shoots smooth and makes a pretty tight ragged hole in the target. I have done nothing but move the rear sight a little left and install a shok-buff from wilson combat. In over 1000 rounds, not one problem. It simply shoots great. I even tried some generic magazines that I picked up and after cleaning and lubing the mags, even they worked. You should have no problems with it.
Mine is great! Very accurate piece.
I only replaced the grip screws with some stainless hex heads.
Cleaned, Lubed it up and off to the range...
