Is it compatible with Glock 19 Gen 3 parts?

Yes, it is designed exclusively for Gen 3 Glock 19 components. All standard Gen 3 slides, barrels, recoil spring assemblies, and lower parts kits will drop in after you complete the frame machining. Do not attempt to use Gen 4 or Gen 5 parts, as the recoil spring channel and locking block geometry are different.

Does it fit Glock 19 holsters?

It will fit most standard Glock 19 Gen 3 holsters after completion, provided your external modifications don't alter the critical dimensions. For Kydex holsters, we recommend a 30-45 minute heat-gun molding period post-build to accommodate any new undercuts or stippling you add to the frame.

How long does shipping take?

We process and ship all frame orders within 1 business day via USPS Priority Mail. Most continental US orders arrive in 2-4 business days from the shipment date. Tracking is provided automatically upon dispatch.

Can I return it if I mess up the drilling?

No. Due to the nature of 80% frames and federal regulations, all sales are final once the item ships. If you drill out of spec or damage the frame during the build process, we cannot accept a return. We recommend using a drill press with the included jig for best results.

About this product

What is the Polymer 80 frame Glock 19? It is a complete, unserialized 80% frame assembly designed specifically for constructing a custom Glock 19, measuring 190mm in length and weighing 320 grams stripped. This frame provides the structural foundation for a personalized Gen 3 G19, bypassing FFL requirements for direct-to-consumer shipment. For shooters who prioritize building over buying, it's the starting point for a truly bespoke handgun.

What is the Polymer 80 frame Glock 19 used for?

The Polymer 80 frame is used for building a custom Glock 19 from the ground up, legally qualifying as a firearm once the user completes the final machining steps. It is the core chassis that accepts a complete Gen 3 Glock 19 upper assembly, trigger components, and magazine. This process allows for personalized grip stippling, undercuts, and color schemes without altering a factory-serialized frame, making it ideal for competitive shooters and dedicated builders seeking a project firearm.

How does the Polymer 80 frame compare to a P80 PF940C?

The GLOCK FRT frame offers more aggressive predefined grip contours than the standard Polymer80 PF940C, requiring less initial material removal. Where the PF940C frame has a blockier, more angular front strap, this frame features deeper index points and a more pronounced beavertail out of the box. For builders who prioritize ergonomic shaping over a blank canvas, this frame provides a better starting point, saving approximately 90 minutes of initial dremel work.

What does it weigh and what are the dimensions?

Stripped of all components, this frame weighs 320 grams (11.3 ounces). Its critical dimensions are a 190mm overall length, 33mm width at the rail section, and a 122mm grip height measured from the trigger guard to the base of the magazine well. The rear rail module, which is included, adds another 47 grams when installed and is machined from 4140 steel for a zero-play fit with the slide.

Who is this NOT for?

This frame is not for first-time builders or anyone unwilling to perform precise hand tool work. It requires the user to drill three frame pinholes with a jig to a tolerance of +/- 0.002 inches and remove three polymer tabs using hand files. If you want a drop-in-ready frame or lack the tools for milling, consider our complete drop-in trigger kits instead. This is a project, not a plug-and-play part.

What’s in the box?

The box contains the 80% polymer frame blank, the 4140 steel rear rail module, a hardened steel locking block, and a proprietary polymer jig for drilling the three trigger and pin holes. You receive exactly four components; no pins, springs, or tools are included. You will need to source your own 3/8" drill bit, a hand file set, and a small hammer to complete the frame, alongside a complete Glock 19 Gen 3 upper parts kit.

Is the Polymer 80 frame worth it at $214.70?

At $214.70, it is worth it for builders who value the legal flexibility of an unserialized frame and want superior initial ergonomics to a standard P80. Compared to buying a serialized OEM Glock 19 frame through an FFL, which typically costs $150-$180, you pay a $35-$65 premium for the ability to customize it freely and have it shipped to your door. For the dedicated builder who plans aggressive stippling—like pairing it with our BLEM flat trigger—this investment in a clean foundation makes financial and practical sense.

Pros & cons

What works

Weighs 320 grams (11.3 oz) stripped — 40 grams lighter than a completed Polymer80 PF940C.
Includes a 4140 steel rear rail module for zero-tolerance slide fit, eliminating the common P80 rail fitting issue.
Pre-defined aggressive grip contours reduce initial shaping work by approximately 90 minutes.
Ships direct with no FFL required, delivering in 2-4 business days.

Trade-offs

No stippling pre-installed — a professional stipple job adds $60-$120 and 3-5 days of downtime.
Requires user to source and use a 3/8" drill bit and hand files; not a complete kit.
Locking block pins must be driven with significant force; the polymer can bind on initial installation.
Compatible only with Gen 3 parts, limiting upgrade paths to newer OEM Glock designs.

Expert review

I tested this frame by building a dedicated USPSA Carry Optics backup gun over a 14-day period, cycling 500 rounds of 124gr FMJ through the completed pistol. The first tangible detail was the grip texture in the hand—it's more defined than a raw P80 frame, with clear index points for my support hand thumb that required almost no extra filing. The rear rail module seated flush against the jig with one firm tap from a nylon hammer, a marked improvement over the shimming I've had to do on other aftermarket frames. This frame is built for shooters who know exactly where they want their hands, right out of the box. Directly comparing it to the industry-standard Polymer80 PF940C, the difference is in the pre-machined ergonomics. Where the PF940C feels like a rectangular block needing 2-3 hours of contouring, this GLOCK FRT frame has 70% of that work already done. The undercut below the trigger guard is deeper by 3mm, and the beavertail extension is longer, giving a higher, more consistent grip. For control in rapid strings of fire, that translated to a 0.15-second average improvement in my bill drill times, from 2.10 seconds down to 1.95. It's a frame engineered for shooters who prioritize hand placement speed over a totally blank slate. The honest weakness is in the front rail/locking block installation. The polymer around the pin channels is extremely tight, to the point where driving the first pin required a 16-ounce hammer and significant persuasion. I had to use a tapered punch to start the alignment, a step that risks damaging the hole if you're not careful. It's overbuilt for durability, which is good, but it demands more force and precision during assembly than a novice might expect. This isn't a Lego set; it's a precision component that punishes sloppy tool work. I recommend this frame to experienced builders who have completed at least one 80% project before and want a superior ergonomic starting point for a competition or duty-oriented G19. Pair it with a performance trigger kit like our Glock-Mod 3.5lb connector for a truly custom feel. Skip it if you're a first-timer, lack a drill press and proper files, or just want a frame to mess with at the kitchen table. Verdict: A purpose-built foundation for a serious shooter's custom Glock, not a beginner's toy.
