ADE Optic Mount/Mounting Converter/Base Plate for 1911 Handgun with Novak/Adjustable Rear Sight to Accept Over 25 Different red dots Such as Vortex Venom/Viper/Burris Fastfire/Sightmark Minishot

A pretty solid mount on my RIA M1 1911 9mm tact ultra

Fit GSG 1911-22 and vortex viper just fine. It has a set screw in front to make up for the non standard sight base on the gsg. It's a little short though. I replaced it with a slightly longer one from the hardware store and it's rock solid and level. I didn't have to alter the mount itself to make it fit at all. You could also shim it with a thin piece of metal and protect the slides finish better.

Mounted this on a friends RIA 1911 and the fit was perfect. The dovetail was tight but I didn't have to modify which was a pleasant surprise. I bedded it to the slide and it's rock solid and the sight has held zero perfectly. Not he wants me to mount one on a different arm if I can find one that fits it's dovetail.

Not even close this pic that says yes is what I have exactly. The pic that says no seams to be the one it fits. Look at the last pic with it on the slide that’s what came I saw that but it’s said it fit low Novack very confusing. The yes seams to be different from last pic.

I actually requested a refund on this item, and decided to cancel the refund and do a little bit of filing. I was able to make this work for my needs. The rear novak slide cut on my 1911 was slightly higher than the mount, forcing the plate to angle down...filed the underside of the plate down and it fits perfect. I thought this was one solid piece, it is not. This is a two piece mounting plate. A sight push will slide in the slidemount, and the plate attatches resting on top with two screws. Was somewhat wobbly, till i filed the plate down. Looks good. I do not like the 2 piece mount and would prefer a solid piece...but with that being said, it functions flawlessly. The online store is also very responsive, and easy to work with. I will be returning to thier online store for future purchases from them. Tho i did not return this item, the store has impeccable ethic, and has earned my business. I may be a picky customer, but this store is sooo good, i would recommend searching thier items before looking elsewhere. Thanks, to this store for being beyond excellent!

Does not fit RMR footprint at all. Not even close.

RIA 1911 Tactical with the Novak Sights (not GI) Well, it didn't fit out of the box. The reason for this is, ADE has a full box of metal around the area that screws into the dovetail bit, and on the RIA, the rounded top part of the slide overhangs the dovetail slightly. Said another way, looking at the bottom of this mount, there is a perpendicular metal lip that separates the transition between rounded slide contact, and dovetail adapter interface. That lip does not fit between the slide and the dovetail adapter bit. Using a Dremel with a stone wheel, I was able to remove the metal following the rounded slide interface, and use a sanding wheel Dremel but to smooth out the final stretch. After this, it fit like a glove. Secondarily, the screws ADE include are not long enough to reach through their optic, the adapter plate, and actually engage the dovetail adapter. They are tapered heads too, so sourcing ones that work was... Challenging. All in all, I would buy again, but would source the screws ahead of time. The grinding is probably only specific to special snowflakes like RIA, which tend to have fitment gremlins with many after market parts

Works as it should added a red dot works perfectly
