A friend of a friend was telling me today that the XD he got a few months ago is shooting low. It's the medium sized Service model in 357 sig. I looked the piece over just to rule out big stuff, but it looks OK.

I suggested shooting off the bench to eliminate as much of the human component as possible and that he was most likely pulling the shots low himself. If that wasn't the problem, I told him to try different ammo brands and types. He's currently shooting some European brand of 140 grain.

Has anyone had (or heard of ) problems with the regulation of the sights on an XD, specifically in 357 sig?
