I got a Series 80 Colt Government model which has a Millet Dual crimped front sight (I bought it used). The front sight is 5mm (.196 to .200 inch) tall from the top of the slide to the top of the sight. The gun came with a high profile LPA adjustable rear sight and it shot too high, about 8 inches at 25 yards and that's with the 6 O'clock sight picture. That sight could not be adjusted any lower. I got a low profile LPA sight and it adjusted to the point of aim but I do not like that sight because it has sharp edges and it's at the very end of its elevation screw, looks like it's going to fly loose at any second. I tried Colt original fixed sight but it shot low. I tried Novak Competition sight and it shot low too. I tried Millett MarkII fixed sight and it shot low too, even though Millett states that a .200 inch front sight has to used with this rear sight. I tried MGW rear but the thing was defective and I almost broke my dovetail trying to install it (thanks to Brownells great service they took it back). Can anyone suggest a rear sight that would shoot at the point of aim at 25 yards with the above mentioned front sight (since changing the front sight is not an option at this time). Thanks.
