Glock 19 Gen 5 OEM Frame

Build or upgrade your Glock with the Glock 19 Gen 5 OEM Frame — a compact, factory polymer frame that houses Glock’s proven fire control components. Engineers reinforced this frame with steel guide rails and built in Glock’s Gen 5 ergonomic upgrades, giving you a dependable foundation for a concealed carry, duty, or range build.

Product Description | Specs for Glock 19 Gen 5 OEM Frame

Glock molds this frame from high-strength polymer and reinforces it with a steel locking block and guide rail inserts for long-term durability. Engineers removed the finger grooves found on earlier generations for a cleaner, more versatile grip, and they added a flared magazine well with a front-frame cutout to speed up reloads.

Compatibility

This frame accepts Glock 19 Gen 5 slides and Gen 5-compatible components. It won’t accept Gen 3 or Gen 4 slides without modification, since Glock changed the rail geometry and barrel specifications for Gen 5. Pair this frame with a Glock 19 Gen 5 slide assembly to complete a 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 5 texture wraps the grip for confident control, and the finish resists wear through years of holster use, training, and daily carry.

• Backstraps: Swap between small, medium, and large to fit your hand
• 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: Add professional engraving or customization
