Red dot mount that fits rimfire rail

Hi folks. I have a Sig Trailside semi auto pistol, with the normal rimfire rail on the barrel. I'd like to mount a Sig romeo zero to it, but I can't find a mount. Any leads? I've tried Amazon, eBay, Google and EGW, but nothing yet. Anyone know of anything? Thanks

Would this work?

Thanks, I tried one tonight, and it tightens up, lop-sided, tried it every which way and it's clocked a little bit no matter what I do.

Utg makes a mount for dovetails.

Thanks, I'll look up utg

Found one utg makes that fits the fast fire. I may go that route. Thanks!

If you want other options, do a "google" for "dovetail mount picatinny rail".

There are a number of them out there, finding something in stock might be a challenge.

Good luck.

You might try bkltech.com. They've been making mounts and rings to fit the 11mm or 3/8's dovetails on foreign and US rifles and pistols for a while. I've had to clean the dovetail and use blue loctite and one that was a real pain got the red treatment. Not on the screws but in the dovetail grooves. I've got riser blocks on my silhouette rimfire rifles that were made by Wayne Merrier out of Brunswick, Ga.
