Compatibility

This frame accepts Glock 17 Gen 4 slides and Gen 4-compatible components. It does not accept Gen 3 or Gen 5 slides without modification, since Glock changed the recoil spring configuration and rail geometry between generations. Pair this frame with a Glock 17 Gen 4 slide assembly for a complete, factory-spec pistol build.

Materials & Finish

Glock reinforces this frame’s polymer construction with steel guide rails and a locking block insert to handle the repeated stress of slide cycling. The Gen 4 texture wraps the grip for confident control, and the finish resists wear from years of holster use, training, and duty carry.

• Magazine Catch: Reverse for left- or right-hand shooters
• Finish: Apply Cerakote or custom coatings (may affect warranty)
• Trigger: Upgrade the trigger bar and connector for a lighter pull
• Engraving: Professional engraving or customization available
