I have a like new, in box, with papers, Glock 23 RTF2. These RTF2s are getting hard to find, and thus one has the straight serrations on the slide, not the ugly "gills". It also has the older finish on the slide that holds up way better than the new, dull finish. I'm asking $550 with an A.E. Nelson leather 3 slot holster. I will email or text pictures. I am open to offers.
