SAMTEC 1911 Sight Mount Plate Colt 1911 Standard Pistol Mount Base for Sightmark, Vortex Venom, Burris FastFire Mirco Red Dot

The angles are correct, it's just a little wide to start with. If you have a micrometer and a file it's an easy half hour install. Measure the old dovetail sight at its base and that's the number you want after filing the new piece, keeping the file flat against the sides. Mine was .329 thousandths and the new part was .334 thousandths. Work slowly, check frequently and you'll get a nice tight fit (as it should be). I've done 2 now and with a little dab of blue loctite and the 1 degree shim they're both holding up well and were easy to get sighted in (1 ADE 6 moa red dot and 1 ADE 3 moa green dot.)

will not fit my Kimber 1911. trying to contact manufacturer for resolution. firing pin block spring exposed. mounting screws not long enough.. material wise this is a well made product. the design is great with the curved lower part of the mount to fit the 1911.

I installed this on a Colt Mark IV 80 1911 officer size 45 and everything installed just fine and felt tight and solid. However, the first time at the range after less than 20 rounds the screw threads that hold the 2 plates together striped totally on one side and partly on the other. After removing everything and trying to see if the screws would still grip one side would just spin and spin and was totally stripped. I saw reports of this happening to others but thought with the cheap price it was worth a try. I found out the hard way that it is not worth even $1 when it does not work. I had a fair amount of thread engagement so the screw went in further than 2 or 3 turns and used blue loctight but still stripped out.

This fit perfectly on the rock island 1911 with the contour of the bottom of the plate. Mounted a crimson trace 1250 on it and it fit the footprint perfectly. The 1250 offers the docter footprint. This will NOT fit RMR optics.

After trying so many more expensive options looking for a sight mount to fit my Girsan MC1911 C this is the one that fit. I had to file down like the tiniest little bit for the sight plate to slide in. It's a nice tight fit put 100 rounds through it and it stayed in place and didn't come loose at all! Overall I'm super happy with this mount and its looks nice to boot.

I really wanted this to work. I have a Browning HiPower that I wanted to put a Dot on, so I bought this mount to match my Burris Fast fire C.It doesn't match the pin cuts in the sight.The mount is good enough, but the description of fit is inaccurate. The Burris Fast fire C requires RMSc, which is not the same as RMR Burris footprints.It the RMR the only footprint you have? I really want this to work on my HiPower.

Fits a RIA 1911 GI, you have to do a little sanding to the insert, but once installed it’s definitely not moving

I looked everywhere for one to fit my new pistol. This one fits perfectly. The only sight I could find that fits atop is the Crimson Trace. My only issue is the screws sheared off after about 20 rounds. I’m looking for some that are stronger.
