I would like an adjustable rear sight for my norinco 1911 and obviously I would need a larger front sight also. Has anyone done this to there's and what sights did you use? I have written millett about what size I need for a front sight and after 3 times I have given up on them. All i want to know is what size of front sight did you use with the corresponding rear sight. I stopped in to Western Gun Parts and you might as well be talking to a brick wall, unless you know exactly what you want they are no help.
