I have an Unfired Glock 19 Gen 5 MOS with Factory front serrations on the slide. This is a fairly new release from Glock. They got rid of the front cutout on the bottom of the frame and they beveled the front of the frame to match the beveled nose of the slide.
If you are unfamiliar with the Gen 5, they got rid of the finger grooves, they added an Ambi slide stop, and they upgraded the trigger/safety plunger. The coating on the slide is very nice and the barrel is their "Marksmanship" Line with improved rifling.

This will come with all factory parts to include the pistol, three 15 round magazines, tools, papers, lock, and optic mounts.
Asking $450 no trade.
