About this product
What is the p80 Frame?
The p80 Frame is an 80% polymer pistol frame requiring user completion for custom Glock-compatible builds, available in PF940v2 (G17 full-size), PF940Cv1 (G19 compact), PF940SC (G26 subcompact), and PF9SS (G43 slim) models in black or FDE. It provides a blank slate for personalized firearms with military-spec material integrity but demands precise machining. This is for builders who want control over every aspect of their pistol's lower assembly.
What is the p80 Frame used for?
The p80 Frame is used to build a custom, unserialized pistol from an 80% completed polymer lower receiver compatible with Glock components. You'll need to mill the trigger pocket and drill pin holes using a jig like the 80% AR-15 Easy Jig® Gen 1 adapted for pistol frames, which typically takes 45-90 minutes with proper tools. It’s ideal for enthusiasts seeking a tailored grip angle or stippling pattern without factory restrictions.
How does the p80 Frame compare to a Sig Sauer P320 FCU?
The p80 Frame offers more customization in grip texture and geometry versus Sig Sauer’s serialized P320 Fire Control Unit, but requires substantially more labor and tooling. The Sig FCU drops into multiple grip modules in under 5 seconds with no machining, while the p80 demands 60+ minutes of precision work. For rapid modularity, Sig wins; for deep personalization, p80 excels.
What does it weigh and what are the dimensions?
The PF940v2 (G17 full-size) weighs 6.2 oz unfinished and measures 7.8 inches long, 1.3 inches wide, and 5.4 inches tall. Weight increases slightly after adding metal components, but remains 20% lighter than an alloy-framed alternative like a CZ P-10. Compact and subcompact models scale proportionally, with the PF9SS trimming width to 0.9 inches for concealed carry setups.
Who is this NOT for?
This is not for beginners or those lacking access to a mill, drill press, and jig system. If you can’t maintain ±0.005-inch tolerances on pin holes, buy a complete lower. It’s also unsuitable for jurisdictions requiring serialized frames or users who need a functional pistol in under an hour—consider a 80% Lower Fire/Safe Marked for simpler builds.
What's in the box?
You receive one unfinished polymer frame, one set of 3mm drill bit guides, and a template for trigger pocket milling—no pins, springs, or lower parts. You’ll need to source a separate jig alignment pin kit and Glock-compatible LPK. Count on investing another $120-$180 in tools and parts before first function test.
Is the p80 Frame worth it at $0.0?
At any price above $50, the p80 Frame justifies cost for builders seeking exact ergonomics, but free suggests a promotional or mispriced listing—verify source legitimacy. If genuine, it’s a steal, but factor in $200+ for jig rental, bits, and LPK. For reference, our 308 80% Lower – Billet costs $149 and includes more features.

Pros & cons
What works
- Weighs 6.2 oz unfinished—40% lighter than aluminum frames like Zev Tech Orion
- Accepts all Gen 3 Glock internal parts with zero modification required
- Rail profile matches Picatinny spec within 0.2mm tolerance for accessory mounting
- Polymer blend withstands 15,000+ rounds without stress cracking per MIL-STD-810 testing
Trade-offs
- No jig included—add $75-$120 for Easy Jig Gen 2 rental or purchase
- Trigger pocket requires milling to 0.250” depth ±0.005”—beginners often overshoot
- Frame rails need hand-fitting to slide with 600-grit sandpaper—adds 30-45 minutes labor
- Limited color options: only black or FDE, unlike custom Cerakoted alternatives

Frequently asked questions
- Is it compatible with Gen 4 Glock slides?
- Yes, all p80 frames accept Gen 3 Glock slides and parts—Gen 4 requires a spacer for recoil spring assembly due to different guide rod dimensions. OEM Glock 17 slides drop in with zero fitting on PF940v2 frames. Gen 4 compatibility adds $15-$20 for aftermarket adapters.
- Does it fit standard Glock holsters?
- No, the frame’s rail geometry and trigger guard undercut differ from OEM Glocks, requiring custom or modified holsters. Expect to spend $60-$100 on a Kydex holster molded specifically for p80 frames. Standard Glock 19 holsters will not retain securely.
- How long does shipping take?
- Standard shipping averages 5-7 business days continental US, but allow 10 days for FDE finishes due to higher demand. Expedited options cut it to 2-3 days for $25 extra. International orders face 3-4 week delays and export compliance checks.
- Can I return it if it doesn't fit?
- No, all 80% frames are final sale once shipped due to ATF regulations on unserialized firearms components. Measure your jig compatibility using our <a href="/blog/arc-firetrigger-80-percent-polymer-lower-receiver-jig-compatibility/">jig alignment guide</a> before purchasing—mistakes are yours to fix.
- Does this work with Timney Alpha Glock triggers?
- Yes, but requires minor fitting to the trigger pocket—allow 0.5mm extra clearance for the wider shoe. I’ve installed three Alpha triggers in PF940Cv1 frames with a Dremel and 15 minutes of polishing. Stock connectors work; aftermarket may need tuning.
