PF940v2 - Polymer80 PF940v2™
Pros & cons
What works
- 8.2 oz unfinished weight—identical to OEM Glock frames for proper balance
- Stainless steel rails rated for 50,000+ rounds—outlasts aluminum rail systems
- Aggressive texture provides 30% more grip surface than factory frames
- Includes precision jig with 0.002" tolerance—ensures perfect pin alignment
Trade-offs
- Requires drill press and router—adds $200-400 tooling cost for beginners
- No front rail module included—must purchase separately for $35-50

About this product
The PF940v2 is Polymer80's original 80% full-size pistol frame kit designed for builders creating custom Glock-compatible handguns. This platform established the modern 80% handgun market and remains the benchmark for reliability and aftermarket support. Building on this frame provides complete control over component selection while maintaining OEM-level fit and function.
What is the PF940v2 used for?
The PF940v2 serves as the foundation for building custom Glock 17/22 pattern pistols without requiring an FFL transfer. You complete the final 20% of machining using the included jig and basic tools, typically taking 2-3 hours for a skilled builder. The resulting frame accepts all Gen 3 Glock components while offering superior grip texture and customization options not available on factory frames.
How does the PF940v2 compare to the 80% AR-15 Easy Jig® Gen 1?
The PF940v2 requires approximately 40% less machining time than our 80% AR-15 Easy Jig® Gen 1 due to its simpler fire control cavity geometry. While the AR-15 jig produces rifle receivers with more complex internal structures, the PF940v2 focuses on handgun ergonomics and shootability—its aggressive texture provides 30% more surface grip than factory Glock frames, making it superior for high-round-count training sessions.
What does it weigh and what are the dimensions?
The unfinished PF940v2 frame weighs 8.2 ounces with dimensions measuring 7.3 inches long, 5.6 inches tall, and 1.3 inches wide. Completed with all internal components, the frame adds approximately 3.8 ounces, bringing total weight to 12 ounces—nearly identical to OEM Glock frames. These specifications ensure proper balance and holster compatibility while providing a solid platform for slide reciprocation.
Who is this NOT for?
This frame is not suitable for first-time builders or those without access to a drill press and router. The machining process requires spatial awareness and manual dexterity—approximately 15% of beginners require second attempts based on our jig alignment data. If you prioritize immediate functionality over customization, purchase a complete pistol rather than undertaking an 80% build.
What's in the box?
The kit includes one 80% polymer frame, one precision-machined aluminum jig, three drill bits (3mm, 4mm, and 6mm), and one end mill cutter. You'll need to provide your own drill press, router, vise, and safety equipment—the entire completion process consumes approximately 45 minutes of machining time plus additional fitting and assembly. All necessary hardware for jig assembly is included, with no additional purchases required for basic completion.
Is the PF940v2 worth it at $0?
At its current price point, the PF940v2 represents exceptional value for experienced builders seeking a proven platform. You're acquiring a system that has successfully completed over 500,000 builds since 2013, with documented reliability exceeding 20,000 rounds in endurance testing. Compared to a complete Glock frame at $250+, the PF940v2 provides superior customization potential while avoiding FFL paperwork—provided you possess the requisite machining skills.

Frequently asked questions
- Is it compatible with Glock 17 Gen 4 slides?
- No, the PF940v2 only accepts Gen 3 Glock components. Gen 4 and Gen 5 slides require different recoil spring assemblies and locking block interfaces that won't function properly with this frame. Stick with Gen 3 slides for guaranteed compatibility.
- Does it fit standard Glock holsters?
- Yes, completed PF940v2 frames maintain identical exterior dimensions to OEM Glock 17 frames—1.34" width at the rail section. They fit 99% of Glock 17 holsters unless the holster uses aggressive retention mechanisms that contact custom stippling or frame modifications.
- How long does shipping take?
- Orders ship within 24 hours via USPS Priority Mail, arriving in 2-3 business days for continental US addresses. International shipments require 7-10 days and additional customs documentation—check local laws before ordering 80% frames to your jurisdiction.
- Does this work with aftermarket triggers?
- Yes, the PF940v2 accepts all Gen 3 Glock-compatible triggers including popular models from Agency Arms, Overwatch Precision, and Johnny Glock. Installation follows standard Glock procedures—expect 15-20 minutes for trigger assembly fitting and function testing.
