    • Sig Sauer 1911 4.2 Inch Barrel with Rail

    When Sig first introduced the “Enhanced” 1911 series, it was met with some skepticism as the frame and barrel length changes were considered a desecration of the venerable John Browning 1911 design. However, as the enhanced models began to circulate through the market, they start receiving outstanding reviews on their fit, finish, and performance. The trick, though, was finding a holster to fit the somewhat oddball 4.2 barrel length on some of the models. A few years later, Sig threw another wrench in the mix by introducing a few of the 4.2 inch barrel 1911 models with a rail.

    Scroll down to the bottom of the page to see all the gun holster models available for this pistol.

    Currently those models include the following (although there are other older models as well):

    • Sig 1911 Carry Scorpion
    • Sig 1911 Scorpion with threaded barrel (which requires a completely different holster fit)
    • Sig 1911 Carry Tacops

    Here are some of the more common questions that we see regarding holsters to fit the Sig 1911 4.2” barrel models with a rail:

    #1 – I have a Sig 1911 with a 4.2” barrel but I don’t know if it has a “rail” or not? How can I tell?

    A “rail” refers to a picatinny rail with a slot cut into the frame of the pistol towards the barrel. This slot is designed as a mounting platform for accessories such as tactical lights or lasers. If you have a look at the image above, the rail is clearly visible in the picture on that pistol.

    #2 – Would a holster made for a Colt Commander sized 1911 with a 4.25 barrel and a rail fit my Sig 1911 4.2 model with a rail?

    In theory it might fit. However, there are very few gun manufacturers who offer a railed 4 ¼” 1911. Most companies who offered railed 1911 models either offer them in a 5” or 4” version. So holster made for a 4” railed 1911 would actually be too small and a holster made for a 5” railed 1911 weapon would be a little long.

    #3 – I have the Sig 1911 Carry Scorpion model with a threaded barrel. Do you have any holsters to fit that?

    Actually any of the holsters listed on the page below are available for a Sig 1911 with a 4.2” barrel with rail and threaded barrel. The threaded barrel option adds a slight upcharge for the holster. This holster option would fit the Sig 1911 Carry Scorpion with TB (threaded barrel) and the Sig 1911 Carry Tacops with TB.

    #4 – I have a Sig 1911 3.3” barrel with a rail. Do you offer anything to fit those models?

    We’d suggest you double check your weapon as, at the time of this writing, Sig wasn’t offering a 3.3” 1911 with a rail. Obviously, that could change in the future.

    #5 - Since I have one of these railed Sig 1911 models with a 4.2" barrel, do I need a special holster for it?

    Since the rail on the frame changes the dimensions of the pistol, the answer is yes. A railed model such as the one above won't fit (at least not well) a holster made for a non-railed 4.2 inch Sig 1911. The rail added additional thickness to the frame width towards the bottom of the frame.

    Any of the holster models listed below are produced in a version to fit any Sig 1911 with a 4.2” barrel and a rail.
