Red dot mounts for 1911 models

This collection contains red dot mounts for 1911 pistols. The mount replaces the rear sight in its dovetail. You need no slide milling and no permanent modifications. On a 1911, the right mount depends mainly on the rear sight cut of the slide.

Find your rear sight cut

1911 makers use different rear sight cuts. A mount for one cut does not fit another. The mounts in this collection are sorted by cut:

• Novak Cut: the largest choice, with mounts for Shield RMSc, Trijicon RMR and Toni System type A and B. EGW type S fits RMSc, DPP and K-series. See Red dot mounts for 1911 Novak Cut.
• LPA Cut: Toni System type A and B and EGW type S. See Red dot mounts for 1911 LPA Cut.
• BoMar Cut: Trijicon RMR, Toni System type A and B and EGW type S. See Red dot mounts for 1911 BoMar Cut.
• G.I. Cut: Shield RMSc, Trijicon RMR and EGW type S. See Red dot mounts for 1911 G.I. Cut.
• Kimber Fixed Cut: EGW type S. See Red dot mounts for 1911 Kimber Fixed Cut.
• Rail Gun Cut: for .22 LR 1911 models such as the Colt 1911 .22 LR Rail Gun and the Hämmerli Arms Forge H1. Trijicon RMR and EGW type S. Some 1911s need a minor modification to the mount. See Red dot mounts for 1911 .22 LR Rail Gun Cut.
• GSG Cut: for .22 LR 1911 models with the GSG cut. A Shield Sights mount for the Shield RMSc footprint. See Red dot mounts for 1911 .22 LR GSG Cut.

The cut is usually named by the maker of the pistol or of its factory sights. If you are not sure, compare your rear sight with the product photos.

Frequently asked questions

Can I put a red dot on my 1911 without an optic cut?

Yes. The mount goes into the rear sight dovetail in place of the rear sight. No milling and no permanent changes, so you can put the rear sight back at any time.

Can I install the mount at home?

Yes, if you have a sight pusher or a punch.

1. Drift the rear sight out of the dovetail.
2. Push the mount into the dovetail and tighten it.
3. Screw the red dot onto the mount with a drop of threadlocker on each screw.

You find the tools in Installation tools.

Which red dots will fit?

It depends on the mount you choose. Every mount takes one footprint or a group of footprints. For 1911 we have mounts for the Trijicon RMR, Shield RMSc, Holosun K-series, Leupold DPP, Docter and C-More RTS footprints.

Find the footprint of your red dot in its specifications and take the mount that names it.

How do I find the rear sight cut of my 1911?

Look at the specifications of your pistol or ask its maker. The common cuts are Novak, LPA, BoMar, G.I. and Kimber. A mount fits only the cut named in its title.

Does the Tanfoglio Witness 1911 mount fit the Custom?

No. The Witness 1911 Custom needs a different mount.
