I have a SIG 1911 GSR. The gun shoots really low and it has NOVAC carry sights. The front sight is the lowest they have .190" so that isn't the problem. I ordered the NOVAC adjustable rear sight and find that I have to send them the slide to machine a cut in FRONT of the dovetail so the sight will fit......SUCKS! My question is: Can I recut my slide for a BOMAR type rear sight and who will do it and install/sell the sight. I want the low mount cut. Why couldn't they just design a rear sight that fits in the original cut?
