No, this not an MOS model.

Derek, no Sir, not from the factory. You can have the slide milled for red dots by Milling Services : https://wepleadthe2nd.com/slide-milling/

No optics ready slides will have "MOS" (modular optics system) designation. This is a standard version. You can have the Slide milled for an optic by many after market companies id recommend Jagerworks as they are agreat balance of affordable and high quality.

Or for a lower cost but less reliable option you can get a dovetail mount

The dovetail mount are much more prone to break and or lose zero, not recommended for a defensive/CCW/Duty weapon really only good for a range toy.
