Sig Sauer P220r

Hello! I bought a Sig P220 a few weeks ago and it took me this long to ask what I or the weapon could possibly be doing wrong. I initially fired it after the horrific ten day waiting period in California (luckily I've moved back to Texas since then) and my round's point of impact was low and left. I made the proper sight adjustments and found, to my dismay, that the point of impact hadn't changed at all despite the fact my point of aim had. I had thought it was human error initially, but I own two other pistols and I don't seem to have a problem putting the rounds where I want them. So, thus it is I bring my problem to the forums where I hope I can gain some insight to the problem. Thank you in advance. :)

How did you adjust the sights specifically? A laser bore sighting device might help.

Actually, I've adjusted the sights three times. The first time I moved them with a brass hammer and it didn't do the trick. Second time I took it to a shop and they adjusted it while using a boresighting system. Still didn't work out so I took it back to the same guys and they drifted it even further. Still same point of impact. I find that the strangest thing, adjusting the sights should have definitely moved the point of impact. I'm baffled.

Have you ever shot a .45acp pistol before? Just because you can shoot a different handgun better, doesn't mean you can shoot a .45acp as good.

Low/left for a right hand shooter is a common sign from jerking the trigger.

That's what I'm thinking. Your healing the gun down. Have you tried shooting it from bench rested position to eliminate human error???

You might be clenching your hand when you squeeze the trigger and that will throw your rounds that direction. It usually isn't your sights. You might be doing what i do, and that is you pull back to 75 percent of the trigger pull then instead of going to 76 on up you jump to 100 percent. This will also throw your rounds off. Spend more time dry firing ti get your hands and trigger control down and then your shots should creep back up.

Good luck.

How tight a group are you shooting and at what distance?

A good rule of thumb to follow before you start adjusting your sights, is that your group should be smaller than the amount you'd like to move your group
