Just returned fron the indoor range for a little trigger time during my lunch break. Colt XSE Gvmt. model, all stock out of the box, about 300-400 rounds through it. Since day one I thought it was me flinching and shooting high about 5 inches and about 4 or 5 inches to the right at 17 yards. a friend I met there with a lot of trigger time on his .45 confirmed that it was the gun, not me. I can see that the rear sight needs to go to the left a hair bit, but how can I adjust for the height difference? BTW, one of my white dots in the rear sight came out too. Could this be a barrel bushing problem or is it normal for this kind of "inaccuracy" out of a stock .45?
