I've got a Colt 1911 XSE that shoots low for me, as do most pistols that I shoot, and instead of filing of the front sight and loosing the white dot, I was thinking about putting on the standard 1911 sight, which would lower the rear sight height. In the Navy when I qualified for ship security force, the Government 1911's I shot were pretty close to POA for me, so does anyone have one I can buy or point me in the direction where to buy one...
