About this product
The P80 Frame - polymer 80 is a stripped, serialized pistol frame designed for building a factory-spec Glock-compatible handgun from parts. It provides a controlled, serialized base for a custom build using OEM or aftermarket components. It is a technical gateway to a personalized sidearm, not a finished firearm.
What is the P80 frame used for?
This frame is used for building a 100% Glock-compatible handgun from a controlled parts kit, such as a Polymer80 Spectre or ReadyMod kit. It is the legal receiver, requiring serialization per federal guidelines. A typical build requires a parts kit, a slide assembly, and about 60-90 minutes of assembly time.
How does the P80 frame compare to the Polymer80 LR-308 80% Lower Receiver?
The P80 frame is a complete, serialized pistol receiver for Glock models, while the Polymer80 LR-308 80% Lower Receiver is an unfinished 80% blank for building an AR-10 style rifle. The P80 Frame arrives serialized and ready for parts installation, whereas the LR-308 requires machining and lacks a serial number unless the user applies for one. This frame is better for a direct pistol build; the LR-308 is better for a custom long-range rifle platform.
What does it weigh and what are the dimensions?
The stripped P80 frame weighs 280 grams (9.9 ounces) and measures 185mm in length, 32mm in width at the rail section, and 125mm in height from the trigger guard to the beavertail. These dimensions are critical for verifying slide and magwell compatibility before final assembly.
Who is this NOT for?
This is not for a first-time builder without prior assembly experience. It requires proper rail alignment, pin installation, and a specific drill bit set for potential modifications. It is also not for anyone in a jurisdiction prohibiting unserialized or home-built firearms without proper FFL procedures.
What's in the box?
The box contains one serialized polymer frame, three frame rails (front, left rear, right rear), and three locking block pins. It does not include a jig, drill bits, or any internal fire control parts. The total component count is seven items, and the assembly requires an additional parts kit and slide.
Is the P80 frame worth it at $189.9?
At $189.9, it is worth it for a builder seeking a controlled, serialized base for a custom Glock clone, saving approximately $80-$120 versus a complete factory frame. It is not cost-effective if your goal is simply the cheapest possible functional firearm, as total build costs often exceed $550 when factoring in a quality slide and barrel.

Pros & cons
What works
- Weighs 280 grams — 85 grams lighter than a serialized aluminum Glock frame
- 100% Gen 3 Glock compatible — uses OEM and aftermarket parts kits directly
- Integrated serialization plate — compliant with federal marking requirements
- Three included frame rails — ensures proper slide alignment during build
Trade-offs
- Grip texture is minimal — requires aftermarket stippling or tape for positive control
- Rail channel depth tolerance is ±0.2mm — may require light filing for perfect slide fit
- No forward accessory rail lugs — limits high-cyclic-rate light mounting options
- Requires a separate parts kit and slide — adds $300+ to final build cost

Frequently asked questions
- Is it compatible with Gen 3 Glock 19 parts?
- Yes. This frame is 100% compatible with OEM Gen 3 Glock 19 slides, barrels, and internal parts kits from vendors like Lone Wolf or Brownells. It will also accept most aftermarket G19 slides that adhere to Gen 3 specs. Verify your slide's inner profile before purchase.
- Does it fit standard Glock holsters?
- Typically, yes, if the holster is molded for a Gen 3 Glock 19 frame profile. However, aftermarket stippling or frame modifications will affect retention. I recommend a holster with adjustable retention, like a Safariland 7378, for a custom-built pistol.
- How long does shipping take?
- Standard ground shipping to the continental U.S. takes 3-7 business days after FFL verification is complete. Express 2-day shipping is available for an additional fee. All shipments require a verified FFL dealer destination after checkout.
- Can I return it if it doesn't fit my slide?
- Returns are accepted within 14 days only if the frame is unused, unserialized (if applicable), and in original packaging. Frames that have been drilled, stippled, or had pins installed are not eligible. Contact support with your order number before initiating a return.
- Does this work with a SureFire X300U weapon light?
- Yes. The integrated Picatinny accessory rail is spec'd for standard-mounted lights like the SureFire X300U, Streamlight TLR-1, and similar models. The rail section is 40mm long and uses a standard MIL-STD-1913 cross-slot pattern.
