3rd set of NM sights
As 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!

Just what the doctor ordered
Took 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.

Better late than never!
I find it amazing, but this sight concept was thought of by NYPD's Jim Cirillo (RIP) whom I trained under back in the nineties. Jim brought his concept to the attention to Ashley Emerson former owner of XS Sights. Apparently Emerson preferred the express sight Vee/Big Dot instead of the Big Dot sitting in the U-notch... their loss. I've tried XS sights... I could not get use to them. Then I found 10-8 Performance and a U-notch sight which now sits in the dovetail of my Commander with a white dot front sight resting comfortably in the U. Its so natural!

Great sight
Installed on a 70 series Colt Government 1911 - fit and function is great. Used in conjuction with .185 front sight.

Very Nice Sight
Used this to replace the rear sight on a 5" 1991 A1 Colt slide. Takes a small amount of fitting but worth it when installed. Great sight pic and works well with OEM staked .185 front . Does not snag, enough of a shelf for one handed slide racking, windage adjustable and a set screw to keep it where you put it. If you are looking for an upgrade that is straight forward,effective and simple to install on a Colt spec slide dovetail this replacement sight is the one to choose.

works good for me
I like this sight because it is simple and sturdy. It is relatively small compared to other sights that seem to stick out too far. This one matches the design and fits perfectly with the appearance of my Colt combat commander. And gives a good sight picture when combined with the .180 OEM type front sight.

Truly premium product
Excellent machining, excellent finish, close initial fit, and expertly designed are all descriptive of this sight. In addition to these factors, this sight is also very reasonably priced. Overall, it is one of the best values when buying a GI rear sight. I absolutely love the attention to detail, as indicated by the nicely performed radius on the edges of the sight. I love it.
