Glock 43X – Zaffiri Precision ZPS.3 Complete Slide – Ported Barrel RMSc Cut Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
This Zaffiri Precision ZPS.3 complete slide is built for Glock 43X-compatible frames and comes assembled with a top-ported black nitride barrel, upper parts kit, and blacked-out co-witness-height sights.
Important: the distributor text may say RMR cut, but the manufacturer part number says RMSc. For this slimline Glock 43X listing, use RMSc in the title, description, alt text, and SEO. Do not list it as RMR and invite a return demon into the shop.
