I picked up a used Beretta 96 INOX a few months ago and have just started taking it to the range. The gun feels great. Grip is excellent and a very smooth shooter. Problem is, I can't hit anything with it. At five yards it's shooting 3" below target. Even resting on the platform, I can't get better than 4" groups at 5 yards. Any suggestions on how I can improve this gun? This is the first gun I've owned that I can't shoot for beans. Here's an example: All the hits on target are with a Glock 23. The 5 holes on the bottom of the target (in the 8 and 9 zone) are from the Beretta.
