This model is not optic ready. I personally would not use a dovetail adapter.I would have a professional gunsmith machine The slide to accept the optic of your choosing.

Hello John, while this model is not optics ready you could use a dovetail mount for a red dot. Hope this helps and happy shooting!

Hi John, this is not optics ready. You would need to replace the rear sight with a dovetail mount >>> mountsplus.com/1911-gi-red-dot-mount.html
Stay safe & have a great day!

Hi John and welcome. Yes, you would need a 1911 G.I. Dovetail Mount in place of the Rear Sight: -- mountsplus.com/1911-gi-red-dot-mount.html ------------ Cheers and stay safe!
