I just now noticed that the rear sight on my Combat Master is missing. I bought it yesterday and fired a box of ammo through it. I carried it with me today, sat down to clean it when I got home and the rear sight was gone! Needless to say, I have looked everywhere for it, but no luck. I guess the previous owner didn't have it tightend very well. Anyway, is this part the same as other 1911's? If not where the heck am I going to find one? Anyone have an extra!?! On the parts page of this site it says that it was a specific part to Detonics, but doesn't give a potential supplier. Please help!!
