I have 2 Beretta 21a pistols. One has textured black grips and shoots straight. The other has smooth wood grips and shoots way right (6" at 7 yards). I am trying to figure out if somehow the gun is just horribly sighted (fixed sights), or if the smooth grips are somehow affecting how I shoot. Like I said, the other 21a shoots straight. I could swear that I am holding the sights dead-on, and there's practically no recoil so I don't think I'm flinching. What do you think? Can a gun with a good barrel shoot 6" off at 7 yards?
