Hey guys, I just noticed that the front sight on my HK USP 45 is not centered on the slide. I bought it brand new in sealed box (before they opened it in front of me at the store) and have shot it several times. It's been a while and I have several guns, but I remember it being very accurate. My question is - is it normal? I assume since it shoots dead on that it was adjusted like that at the factory. Thoughts? Thanks!
