This is a complete upper slide/barrel unit for a Glock 26 in 9mm. It has a titanium finish and appears unused. Bought it thinking I could swap it out for my 40 cal upper to run 9mm but I have the wrong frame (23). I needed to have the model 27 frame. By all resources this will drop on a Glock 27 40 cal frame and then you can run 9mm from it. I can ship it for 9.00 usps tracked. 175.00.
