Please don't hang me for this but I just want to make sure before going forward. My Sp 01 seems to be shooting to the left by around two-two and a half inches at about ten to fifteen yards out or so. There is a set screw on this pistol so I was going to loosen it and tap it to adjust the rear site a bit. Shooting to the left so I adjust to the right? Needless to say I am new to this so any help would be cool. Thanks
