I think you will find that a gen 5 slide is not compatible with a gen 4 frame. Internals are quite a bit different. I'm not sure what they are advertising?

I decided to try an Trijicon RMR on a Glock, currently have two G17 for self defense pistols. Should I buy just a slide for one or should I get an additional G17 and be dedicated to the optic?
