Bought this back when I was buying and customizing Glocks quite frequently and honestly forgot I even bought it until it showed up. It is optic cut also with the RMR footprint. Bad thing about that tho is when it arrived, I didn't have any Gen 3 19s to put it on and not customizing any Glocks at all at this moment. So figured I would post it so someone else could use. I paid $200 for it and only asking $150obo. Now it is a "stripped" slide which means you have to use the internals from the slide your taking off to put this one on. Text 602-341-075five if you have any questions.
