Unfortunately there are no Optic Ready versions available of this model. Best bet would be to send out that slide and have it milled for the optic of your choosing.

Hi David, unfortunately RIA does not make an optics ready version.
Stay safe & have a great day!

David, this model is not optics ready and not aware of any that are. Sorry but hope this helps.

Hi David and welcome. Unfortunately, not currently. This model has a Novak Cut Rear Sight slot and a Novak Cut Optics Plate of your Optics Choice would work : egwguns.com/pistol-and-red-dot-mounts/mounts-by-firearm-brand-sight-cut/novak/ ----- Cheers and stay safe!

sorry RIA does not offer any optic ready 1911s and no other company offers the 22TCM Girsan does offer a 17 round 1911 a2 optics ready in 9mm and you should be able to get a 22TCM barrel from RIA to fit to the Girsan (gunsmith required) in fact the RIA gunsmiths may fit it for you Girsan optics ready here budsgunshop.com/product_info.php/products_id/155022/european+american+armory+girsan+witness2311+9mm+4.25+com+or+black
