The only issue I ever had was when shooting @ 10-15 feet, mine keyholed awful. I went to another forum fond of those pistols and apperently it's very common with a simple fix. The crown wasnt enough, so ya take one of those knife sharpening rods (crock stick, moon stick) with the round nose, put it against the muzzle and do the old play-doh roll on the stick. It defines the crown a touch and after that, it is dead eye on. The accuracy has suprised me immensly! I will say this, mine is in 22mag, and Holy Ba-Jesus that thing is LOUD.
