Grit Grips G43X/G48 Serialized Pistol Frame, Gray

This is an assembled, serialized pistol frame built for G43X and G48 pattern pistols. The frame comes complete with a steel locking block, full lower parts kit, and magazine catch. It's constructed from glass-reinforced polymer with nickel-plated rail inserts molded directly into the frame. The grip angle measures 18 degrees, which is noticeably reduced from the standard OEM grip angle of approximately 22 degrees. This frame arrives fully assembled and ready to accept a compatible slide.

Grip Angle and Ergonomics

The 18-degree grip angle on this frame represents a meaningful departure from the standard OEM 22-degree angle. This reduction promotes a higher hand position on the grip, which many shooters find improves control and reduces muzzle rise during rapid fire. The proprietary directional grip texture is molded directly into the frame and provides a custom stippled appearance without requiring aftermarket modifications. Combined with the extreme double-undercut trigger guard and extended beavertail, the frame geometry is designed for enhanced purchase and comfort during extended shooting sessions.

Complete Lower Parts Kit Integration

This frame includes a full complement of lower parts: trigger assembly with trigger bar, trigger housing with integrated ejector, trigger spring, trigger pin, trigger housing pin, 5-pound connector, enhanced slide stop lever with spring, slide lock with spring, magazine catch, and magazine release spring. The locking block is steel with a natural stainless appearance and is compatible with G43X-pattern frames. Because all these components are pre-installed and assembled, you avoid the complexity of individual component sourcing and installation. The magazine catch is low-profile with a serrated release surface and matte black finish.

Frame Construction and Materials

The frame itself is molded from high-strength glass-reinforced polymer with nickel-plated rail inserts that are integrated during the molding process. This construction method provides durability while maintaining the lightweight characteristics of polymer frames. The frame is serialized, which means it is legally classified as the firearm and requires FFL transfer. The frame is compatible with most G43X and G48-pattern aftermarket components and holsters designed for these platforms, though it requires the proprietary Grit Grips magwell and is not compatible with standard OEM G43X or G48 magwells.

This product is a serialized firearm component and requires FFL transfer and compliance with all applicable federal, state, and local laws. Follow safe handling and manufacturer instructions. This frame is not manufactured, authorized, endorsed, sponsored, or warranted by GLOCK, Inc. Guide rod and recoil spring are not included. Backplate is not included.
