1911 NM Rear Sight

Description

Our National Match style rear sight is designed to fit into the dovetail of GI pattern 1911 pistols. Its extra thick serrated blade is .315" tall (total height, from base to top of blade) for compatibility with new production Colts, and features a .140" wide U notch. User installable (with some hand fitting), no machining required. The newly revised design includes a more rounded profile and additional edge chamfers to improve comfort for handling and carry.

FITS: GI pattern dovetails such as Colt and Springfield Armory with GI pattern sights.
Compatible with: front sights of .175-.185" height.

Is direct replacement for Colt, Springfield Armory, and other 1911s with GI/Milspec rear dovetail. Compatible with factory front sight on Colt 1991A1, new production Series 70 reproduction, and Springfield Armory Milspec models, and does not affect point of impact.

**Be aware that older production Colts with the very low GI style "thumbnail" front sight will require a taller front sight to work with this rear. Machining of the slide is typically necessary and recommended to install a modern dovetail front sight. We neither recommend nor know of any options for traditional style staked on front sights. High profile staked on fronts were bad when we had them in the 80's - they fell off a lot due to the extra weight/inertia from the mass - and they are not any better of any option now that we have dovetailed fronts available.

10-8 NM rear sight

Posted by Chip on 6th Mar 2013

Impressed with the quality of manufacture, and the small amount of fitting required. Target aquisition is much faster, and my shooting greatly improved. I wish someone would make a gold bead front for use with older Colt's with the small tenon, won't mill my slide. How about it 10-8?

NM style 1911 rear sight

Posted by Ashley on 6th Mar 2013

Service and delivery worked out fine. Visual and tactile review of part was very satisfactory. Please receive my very satisfied report with the qualification that this rear sight has not yet been installed and used. I did "jerry rig" it with tape to check the sight picture and remained enthusiastic and satisfied.

Awesome

Very nice sight. Serrated with the wide notch is great. I use wide .140 notches on my Fn's, Glocks, and now 1911's. My only complaint is 10-8 does not offer a stake on .090 width plain black serrated front sight to match. It would save on shipping. I will be ordering another soon for one of my other 1911's.

Excellent product

Posted by Ken Brooks on 19th Jul 2012

The 1911 NM Rear Sight is excellent quality. It is much sturdier than the factory sight and has a wider aperture, making it easier to find the front sight. It took a minor amount of fitting with a file to get it onto the slide, but installation was reasonably simple. I tested it immediately after installation and it simplifies the sight alignment/sight picture problem significantly over the factory sights.

Best Upgrade To A Stock Rear Sight.

Posted by Bob Henckel on 28th Jun 2012

All my handguns have 10-8 rear sights. I ordered the NM Sight for a retro 1911 build, as I wanted the same sight picture as my other handguns, but wanted to keep the retro style. This sight delivers on all counts. As with all 10-8 products the quality is exceptional.

Best replacement rear sight for stock dovetail

Posted by A.T.U. on 1st Nov 2011

I installed the 10-8 NM rear sight on my Colt 1991A1 and what a difference it makes. The original rear sight was thin and prone to breaking. The 10-8 sight is beefier and has a better sight picture..I can actually now see the front sight with my aging eyes. My groups have tightened up as well! This is definitely the rear sight you want to get if you want to replace your rear sight without going through the expense of having the dovetail milled out for a Novak cut. I did this to keep my 1991A1 as GI-looking as possible (spur hammer, arched MSH, no beaver-tail, short trigger) and I'm glad I did. Thanks 10-8 Performance for another high quality product!
