Fits Glock 19 Gen 3 OEM frames and Polymer80 PF940C aftermarket frames. The Polymer80 PS9 ships fully assembled — slide, 9mm barrel, complete slide internals, iron sights, and recoil spring assembly are all installed. Mount it on your completed lower and you have a range-ready upper.
Both the slide body and barrel are finished in black nitride over 17-4 stainless steel for corrosion resistance and consistent long-term wear. Front and rear serrations provide firm purchase for press checks and manual slide manipulation. No optic cut on this slide — it runs iron sights as shipped.
