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 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.
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.
- FITS: GI pattern dovetails such as Colt and Springfield Armory with GI pattern sights.
- Compatible with: front sights of .175-.185" height.
NiceI had a gunsmith install this sight on a Springfield Mil-Spec. It took a bunch of fitting he said but looks great. Haven’t shot yetDan Weller
1911 NM REAR SIGHTThe 1911 NM REAR SIGHT is solidly built, and the bluing is a close match to the bluing of my Colt 1911 Government. I paired it with a HIVIZ Front Sight for Tenon Style 1911. The 10-8 rear sight accommodates front sight heights .175-.185. The HIVIZ front sight height is .180.Patrick Anderson
1911 NM Rear SightsThese sights are awesome. Put them on my Colt Commander which is my duty weapon at my agency.They look great and perform as expected. Be prepared for some file and stone work depending on the weapon you install them on, but other than that no issues. Emailed back and forth with Mr. Yam and customer service is great.Austin Miles McKee
National match 1911 rear sightExcellent replacement for the Springfield mil spec rear sight. It was about .010" oversized. Took a few minutes to fit which was no big deal. It is easier to shoot with both eyes open with this sight.HAWK
The way it should have come from ColtThe tiny GI-style rear sight on my '98-issue Commander was shredding the lining of my suit coats and was impossible to see during combat shooting. I was convinced I would need to replace both front and rear sights. The 10-8 NM sight was an easy fit with a few minutes of work with a fine India stone. The finish matched up perfect with my Colt, the no-snag design doesn't tear up my cover garments, and it's perfect for one-handed charging if my support hand gets injured. Best of all, I discovered I didn't need to replace my front sight because the NM rear sight has a much larger U-shaped notch that makes it substantially easier to pick up the front sight during fast shooting. I'm not one for flamboyant Gucci-gear mods on a pistol design that JMB got right 100+ years ago, and this sight is everything I want on a real combat piece. I stake my life on this gun, and the fact that it wears a 10-8 Performance NM rear sight is the highest praise I could possibly give.E. A. Morales
3rd set of NM sightsAs always 10-8 sights are the best! back in 80s all I used on my 1911s were Bomar, once my Dept clear us us to carry 1911s for concealed carry I tried out my first set of 10-8 U notch rears with a gold dot front and that is all I have run since the the very first days of 10-8! Now that my kids are buying their own firearms their now using 10-8 set ups. Thank you Hilton for providing us with a great product!James Woodall
Just what the doctor orderedTook some needle filing and whetstone work but fits great and looks much better than the factory white dot. The larger "U" notch gives a much clearer and faster sight picture. I wanted a "drop in" because i didn't want to cut the slide on my Colt Combat Commander..this fit the bill perfectly! Couldn't be happier.Curtis
