Like new Glock 19X MOS. This is the special model that came with the RMR cut slide and threaded barrel. 2 19rd mags through it. I put a Glock 19x factory non-threaded barrel in it because I didn't want the threaded barrel for better holster function. Comes with a Steiner dot and Surefire x300 light, both of which function perfectly. The x300 was used on a couple of previous pistols but the Steiner was bought new with the pistol and includes box. Comes with a holster, 3 mags & original case as well. Willing to sell the light and/or dot desperately.
