Description
Polymer80 Glock 19 Gen 3 Frame Kit
Build a custom pistol around your preferred slide, barrel, and internals with the Polymer80 Glock 19 frame kit. Designed for Gen 3 Glock 19 parts compatibility, this kit provides the structural foundation for a fully customized defensive or range firearm. Each frame is precision-molded from high-strength polymer and includes all necessary jigs, bits, and pins to complete the lower receiver. The Polymer80 Glock 19 platform is widely recognized by builders for its ergonomic grip angle, textured frame surfaces, and integrated accessory rail.
Overview
The Polymer80 Glock 19 frame kit is a non-serialized 80 percent lower receiver that requires final machining of the fire control pocket, trigger housing pin holes, and front locking block pin holes. Once completed, the frame accepts all standard Gen 3 Glock 19 upper assemblies, magazines, and internal parts kits. This allows the end user to assemble a full-size compact handgun without the need for a serialized, transferable frame. The kit is manufactured by Polymer80 in the United States and is sold as a collection of raw components intended for personal fabrication. All legal requirements regarding serialization and transfer of the finished firearm remain the responsibility of the builder.
Features and Specs
- Manufacturer: Polymer80; category: parts; Gen 3 Glock 19 compatibility; includes three pin jig, drill bits, end mill, and frame fixture
- Frame material: black, textured polymer with reinforced front rail section; accepts standard Glock 19 trigger housings, locking blocks, and slide release assemblies
- Integrated Picatinny-style accessory rail for mounting lights or lasers; improved grip texture compared to factory frames with undercut trigger guard for higher hand position
The frame retains a 4.02 inch barrel length compatibility and a standard 15 round magazine capacity. Overall frame width is 1.02 inches at the slide catch. The kit does not include a slide, barrel, recoil spring, or magazine. Builders must source these components separately to complete the firearm. The required machining steps involve three drill operations and one milling pass; all tooling is provided in the box. The resulting firearm, once assembled, functions identically to a factory Glock 19 Gen 3.
Who It Is For
This Polymer80 Glock 19 kit is intended for experienced firearm builders who possess basic tool proficiency and a clear understanding of federal, state, and local laws regarding the manufacture of firearms for personal use. It is suited for individuals who want to customize grip contours, trigger feel, and slide finish without purchasing a complete factory pistol. The frame is also appropriate for shooters who prefer the compact Glock 19 ergonomics and want a dedicated lower for competition, home defense, or training. This product is not intended for first-time gun buyers or individuals who lack the mechanical ability to safely complete the machining process. The completed firearm must comply with all applicable laws, including any state serialization requirements for personally manufactured firearms.
Shipping and FFL
This Polymer80 Glock 19 frame kit is classified as a non-firearm component under current federal regulations and does not require shipment to a Federal Firearms License (FFL) holder. It can be shipped directly to your residential or business address. However, local, state, and municipal laws vary. Some jurisdictions restrict the purchase, possession, or completion of 80 percent frames. It is your responsibility to verify that this product can be legally purchased and possessed in your location before ordering. The unfinished frame does not include a serial number and, by itself, is not a firearm. Once you complete the machining and assembly, you may be required to serialize the firearm in accordance with state law. We do not provide legal advice. If you have questions about the legal status of personally manufactured firearms in your area, consult with a qualified attorney before purchase. All sales are final. No returns or exchanges on unfinished frames.
