Fits Glock 19 Gen 1, Gen 2, and Gen 3 OEM frames plus Polymer80 PF940C and GST-9 builds. Not compatible with Gen 4 or Gen 5 frames — the rail geometry and recoil layout are different. This is a stripped slide; a 9mm barrel and slide completion kit are sold separately.
Finish is hard black DLC (Diamond-Like Carbon) bonded to 17-4 stainless. DLC outperforms nitride in surface hardness and corrosion resistance and won't chip on muzzle edges or slide-stop corners the way Cerakote can. It's the right finish for a carry gun or a slide that will see consistent range time.
Slide specs:
To finish the build: Gen 3 Glock 19 9mm barrel, slide completion kit, iron sights or RMR-footprint optic.
Optic mount screws: 6-32 x 1/3 in for the cover plate, 6-32 x 7/16 in for an RMR-footprint optic. Use the optic manufacturer's screw kit when available.
Lube the rails before first install and hand-cycle the slide 50 times to confirm smooth lockup and barrel hood timing before live fire.
