Problem with my sights?

[FunYet]

I have a HK USP Compact 9mm that I'm struggling with. All of my shots end up about 3/4 inch below and to the left of the bulls-eye. All shots impact in a very tight 50 cent sized area. I'm already aware of the target that shows point of impact error due to flinching, jerking the trigger, too much trigger finger, too little, etc. I do not have this problem with any of my other guns and another shooter had the same results so I don't think this is due to user error. The rear sight is dead center in the dovetail and so is the front sight. What else could be the problem? I bought the gun used so I have to wonder if the sights are not the correct sights for this gun. What else could cause this? It's weird, no matter how I try to compensate the shots all group in the low and left area. As I said, it's a nice tight group. I just wish I could get the group in the center of the target.

Ideas?

If your group is tight and consistent, it's probably the sights.

There's nothing wrong with drifting your sights for windage a bit.


Assuming you've got dovetailed rear sights that are fairly normal, you'll need a punch, a hammer, and a perfect willingness to wham the heck out of your gun.

IMO, before you whack anything on your gun...even it being a used gun, I'd bring it to a professional. Take my word for it.:banghead:
