The Cross Armory CRG4OKBK 3-Piece Extended Kit for Glock Gen4 gives you a practical upgrade path for shooters who want better ergonomics and control on their Gen4 platform. This three-piece kit combines extended components in durable steel and aluminum construction, designed to work seamlessly with Glock Gen4 pistols. Whether you're running a competition rig, a duty gun, or a personal-defense carry piece, extended controls can make a real difference in how naturally your hand indexes the weapon and how quickly you can operate the safety and slide stop under stress.

Cross Armory parts are purpose-built for Glock users who don't want to settle for stock ergonomics. The black steel and aluminum finish fits the tactical aesthetic and holds up to regular use and cleaning. The three-piece design means you're getting a coordinated upgrade rather than mixing and matching different manufacturers—everything works together as intended.

Installation is straightforward for anyone comfortable with basic Glock armory work. Keep in mind that this kit is tailored specifically for Glock Gen4 models, so verify your pistol generation before ordering. If you're upgrading a Gen3, Gen5, or other variant, you'll need a different kit.
