I have a Beretta 92FS and am wondering how much "wiggle" is considered normal in the barrel when the slide is forward? Mine has a small but noticable amount. The reason I ask is than with most of my other handguns I'm a decent shot (not great but "serviceable"). With my 92 my groups tend to open up quite a bit. It makes me wonder if the barrel wiggle is not allowing it to reset to the same position every time. I'm not looking to blame the equipment for what may very well be operator error but was curious so thought I'd ask.
