There was a small number of pistols produced about 3 years ago that suffered from premature unlocking, which caused accuracy issues, prior to that, and after that, no problem. My 7 year old abused, high round count gun will still do everything you ask of it with the factory barrel. Assuming of course that your expectations are reasonable (it is not a target pistol, but will let you hit brain box shots at 25 yards) and skill level are up to it. I spent last Tuesday hitting post it notes 10 for 10 at 15 yards, with 50K through the gun.
