    Since there are plenty of 1911 sight cut's out there, I thought that I would post the different dimensions that i have come across.

    Novak is pretty much the standard cut for 1911 sights.
    Front: 65° x 330" x .075" (have also seen .060" and .070")
    Rear: 65° x .495"

    Springfield used to use the standard Novak rear cut, but it's changed since after ~2002 to a smaller cut.
    Front: 60° x .330" x .078"
    Rear: 65° x ~.490"-.485" (this is just a smaller cut in the dovetail, which requires filing down the sight to fit)

    STI
    Front: 60° x .300” x .074"
    Rear: Novak (fixed) 65° x .495” or BoMar (adjustable)

    Armscor (RIA Tactical and Citadel)
    Front: 65° x .330" x .085"
    Rear: 65° x .487" (similar to Novak, but needs to be fit like the Springfield.)

    Dan Wesson uses a combination of standard Novak rear and Springfield front:
    Front: 60° x .330" x .078"
    Rear: 65° x .4.95"

    Kimber has it's own sight cuts.
    Front: 65° x .330" x .070”
    Rear: 60° x .3605" x .194"

    Wilson Combat:
    Front: 60° x .300”
    Rear:



    Smith & Wesson has it's own sight cuts. I haven't looked into what they are.

    Taurus PT1911's also have a proprietary cut on their slides that prevent using standard dovetail sights.

    Okay, another noobie question. I have tried to find the answer with no such luck. My ATI has Novak "drift-adjustable sights", would that be the same as listed above? Also I got a free set of Trijicon CA01 sight coming to me, will those fit? If not how much would it run me on average to get a gun smith to do it? I'm thinking about once I get this thing back from ATI I'm just going to trade it for something else... I can find anything about anything on this thing on the google machine...

    the rear is probably a Novak cut (though some fitting may be required), but hard to say what the front sight cut is.

    hi.
    any idea about the Norinco NP29's dovetail cuts? (front sight is dovetail, not tenon).

    I believe your Rock Island measurements are off. Taken directly from Armscore -
    FRONT - .330" x .075" x 65 degrees
    REAR - .495" x 65deg standard dovetail cut

    What are the specs for a colt gov model, I have a old standard Colt 1911 that I want a new adjustable rear sight. The frame is a 1914 and the slide is a few years newer, with the horse logo in the middle. Any recommendations for a good sight? It also has a rail on top the slide, both front and rear set pretty tall.
