G80 Grip Module

The G80 Grip Module is a polymer housing designed to accept the G80 Unfinished Receiver (FCU). It provides the ergonomic grip frame, trigger guard, magazine well, and accessory rail for your completed G80 pistol build. Manufactured using HP Multi Jet Fusion technology from PA11 nylon, it delivers the proven ergonomics and feel of a Glock G19 Gen3 in a purpose-built modular design compatible with G19, G23, and G32 Gen3 components.

PA11 (Polyamide 11) is a high-performance engineering thermoplastic derived from renewable castor oil. It offers exceptional impact resistance, flexibility, and chemical resistance—outperforming standard nylon materials like PA12 in toughness and elongation at break. The Multi Jet Fusion (MJF) printing process produces fully dense, isotropic parts with consistent strength in all directions, making PA11 ideal for firearm grip modules that must withstand repeated recoil stress and real-world carry conditions.

Yes. The G80 Grip Module is designed with a sleek profile comparable to the Glock G19 Gen3, ensuring compatibility with most holsters designed for that platform. The external dimensions and accessory rail placement match standard Glock Compact geometry, so your existing Kydex, leather, or hybrid holsters for the G19, G23, or G32 should work without modification.

The G80 Grip Module accepts standard Glock Compact magazines in all supported calibers—G19 (9mm), G23 (.40 S&W), and G32 (.357 SIG)—from Gen3 through Gen5. Magpul PMAG 19 GL9 magazines are also compatible for 9mm builds. This gives you access to the most widely available and affordable pistol magazines on the market. Higher-capacity G17/G22/G31 magazines will also function but will extend below the grip.

120R is the grip module standard developed by Defense Distributed for the G100 platform. Because the G80 Receiver shares the same chassis dimensions as the 120R receiver, all G80 and G100 grip modules are fully interchangeable. This means you can swap between any 120R-compatible grip—including open-source designs available on the G80 downloads page—without any modification to your receiver.

Yes. Defense Distributed provides open-source CAD files for G80 grip modules on the downloads page. You can manufacture these designs yourself using 3D printing, CNC machining, or any other method you prefer. The files are free to download and can be remixed or customized to suit your preferences—whether that’s adding stippling textures, adjusting grip angle, or incorporating features like reversible magazine releases for left-handed shooters.

The completed G80 Receiver drops directly into the grip module from above. The receiver is secured using the same pin locations as a standard Glock—the front and rear grip pins pass through the grip module and receiver to lock everything together. No special tools or modifications are required; it’s a straightforward drop-in installation once your receiver is finished.

The key difference is modularity. A Polymer80 frame is a single integrated unit containing the serialized fire control components, rails, and grip in one piece. The G80 system separates these functions: the steel FCU (receiver) contains the serialized fire control components, while the grip module is simply the ergonomic housing. This means you can swap grip modules for different textures, colors, or ergonomics without replacing your completed receiver—and the steel FCU offers superior durability compared to polymer-integrated rails.

No. The G80 Grip Module ships as the grip frame only—it does not include a lower parts kit, magazine release, slide stop, or trigger components. You’ll need to source a Glock G19, G23, or G32 Gen3-compatible lower parts kit separately. Note that certain pins and springs from standard Glock LPKs are replaced by components included with the G80 Receiver.

No. The grip module is not a firearm or regulated component under federal law—it’s simply a polymer housing with no fire control function. The serialized component in the G80 system is the steel Unfinished Receiver (FCU). This is why grip modules can ship directly to your door without an FFL transfer and can be freely swapped, customized, or 3D printed without regulatory implications.

Yes. The G80 system is fully compatible with Glock G23 (.40 S&W) and G32 (.357 SIG) Gen3 components in addition to the G19 (9mm). Simply pair your completed G80 Receiver and Grip Module with a G23 or G32 slide, barrel, and appropriate recoil spring assembly. The grip module itself is caliber-agnostic—the magazine well accepts all Glock Compact double-stack magazines across all three calibers.

The standard G80 Grip Module is manufactured in Multi Jet Fusion PA11 Black. Additional color options may be available—check the product page for current offerings. Because the grip module files are open-source, you can also manufacture your own in any color your printing service or equipment supports, or have a custom grip Cerakoted to match your slide.

Yes. The G80 Grip Module features a standard Picatinny-style accessory rail forward of the trigger guard, compatible with most weapon lights and laser units designed for the Glock G19/G23/G32 platform. The rail dimensions match the Glock Compact Gen3 specification for broad accessory compatibility.

PA11 produced via Multi Jet Fusion is exceptionally durable for firearm applications. The material offers high impact resistance, excellent flexibility without brittleness, superior chemical resistance to oils, solvents, and cleaning agents, and UV/weather stability for everyday carry. Unlike injection-molded polymers, MJF parts are fully dense with isotropic properties—meaning consistent strength regardless of print orientation—making them well-suited for high-round-count use.
