Cruxord Back Plate Spartan - Fits Glock 43

The Cruxord Back Plate Spartan for Glock 43 is a precision-engineered slide component designed for operators who demand functional durability and clean aesthetics on their compact carry pistol. This back plate serves as both a protective cover for the rear slide rails and a platform for mounting optional accessories, making it essential for customized Glock builds. Whether you're outfitting a duty gun, competition platform, or personal defense firearm, a quality back plate directly impacts how additional optics, sights, or mounting systems interface with your slide.

Manufactured in the USA, the Cruxord Spartan back plate combines precision machining with a refined design that minimizes snag points and maintains the subcompact profile the Glock 43 was built for. At just 0.05 lbs, the plate adds negligible weight while delivering rigid reinforcement to the rear slide assembly. The Spartan pattern finish resists corrosion and fingerprints, and the low-profile geometry ensures reliable clearance during slide racking and press checks without catching on clothing or gear during tactical movement or concealed carry operations.

Law enforcement officers, armed civilians, and competitive shooters working with Glock 43 platforms will appreciate the bolt-on simplicity and direct fitment this back plate provides. Installation requires only removal of the existing factory rear plate and application of thread-locking compound to the mounting fasteners—a five-minute task that requires no gunsmithing. The Cruxord Back Plate Spartan is engineered specifically for Glock 43 slide geometry, ensuring zero tolerance gaps and reliable function across thousands of rounds.
