The Cross Armory Extended 3-Piece Kit (brand part number CRG4OKRD) upgrades three of a Glock Gen4’s most-handled controls in one purchase: a dimpled pin set, an extended magazine catch, and an extended slide lock. Cross Armory machines the slide lock and pin set from 4140 steel for strength and finishes the aluminum magazine catch in a red anodizing that adds a visible accent without changing how the gun handles. Every part in the kit is sized to keep the pistol holster-safe, so a duty or carry holster still fits after the upgrade. It’s compatible with the Glock 17, 19, 20, 21, 22, 23, 26, 27, 29, 30, 31, 32, 33, 34, 35, 40, and 41, all Gen4.
