1911 rear sight ?




Can anyone tell if the rear sight grove in the slide of a 1911 is the same as any of the commercial cuts such as a Novak or Bo-Mar etc., or is a proprietary cut unto the original Govt. model? I am looking to replace my rear sight with an adjustable. Thanks for the help, Larry.

The rear dovetail in a standard Colt slide (O1991, Series 70) is the same spec as has been used since 1911. It is not considered proprietary, it is the standard. Aftermarket sights have always been made either to fit the standard Colt dovetail or else required machining to fit their own, proprietary sizes. Novaks, Bo-Marks, Heinies, all require machining of the slide to their own dimensions. For an adjustable sight that fits the standard Colt dovetail you will need to peruse Midway or Brownells' websites and look for sights specifically meant ot fit the Colt factory dovetail, and accept the fact that they'll stick up from the slide. The Novaks, etc are considered "Lo-Mount", meaning by being cut into the slide they sit lower on the slide.

If however you are asking about a Colt XSE, they use the Novak-style cut.

Try not to fall into the common trap of wanting to replace everything on your new 1911 just to make it "better". Know what you're changing out, and why. You may spend a lot of money fixing things that weren't broken to begin with. Shoot it for at least 500 rounds, then decide what you don't like and want improved. Vintage 1911's should NEVER be refinished or modified because it ruins any value they had as a collectible firearm.
