I am in the middle of retro-fitting my new Gold Cup. I want to replace the dovetail front sight. I want one that is angled forward (so it doesn't snag), I want it serrated (so it doesn't glare), I want a white dot (so I can see the dang thing). Brownell's probably has exactly what I want. My problem: I have no idea what the measurements are. I don't have the tools to measure either. All I need is height and width and dovetail cut. Does anybody know? It has the colt version of the BO-MAR sights. The gun is less than 3 years old. This is the only thing I really lack, can somebody help me or send me in the right direction. TIA!
