About this product
The Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit is a 3-pack of unfinished polymer frames and machining jigs compatible with Glock 17/22/24/31/34/35 components. Production has been temporarily halted, making this a final opportunity for acquisition. Cryptocurrency payments are recommended for additional privacy protection.
What is the Polymer80 PF940v2 3-pack used for?
These frames are used for building custom Glock-compatible pistols from 80% complete receivers, requiring approximately 2-3 hours of machining per frame using the included jigs. The process involves drilling pin holes and routing the fire control cavity with standard workshop tools. Each frame accepts Gen 3 Glock slides and components for full-size 9mm, .40 S&W, and .357 SIG configurations. This kit provides enough frames for multiple builds or spare parts.
How does the Polymer80 PF940v2 compare to the 80% Lower Fire/Safe Marked - Anodized Black?
The PF940v2 is better for handgun builders while the 80% Lower Fire/Safe Marked serves rifle platforms. The pistol frame weighs 8.2 ounces unfinished compared to the rifle lower's 11.3 ounces. Polymer construction makes the PF940v2 42% lighter than aluminum alternatives but with lower heat resistance. For AR-15 builds, the 80% Lower Fire/Safe Marked offers superior mounting options for buttstocks and buffer tubes.
What does it weigh and what are the dimensions?
The unfinished frame weighs 8.2 ounces with overall dimensions of 7.3 inches long by 5.1 inches high. The polymer thickness measures 0.15 inches at the rail sections, providing adequate rigidity for slide operation. The jig adds 1.8 pounds to the shipping weight and measures 9.2 x 6.4 x 3.1 inches. Total package weight for three frames and jigs is approximately 4.7 pounds.
Who is this NOT for?
This kit is not for beginners without machining experience or those seeking a ready-to-shoot firearm. The frames require precise drilling and routing operations that demand workshop tools like a drill press or router. Individuals in jurisdictions restricting unfinished receivers should avoid purchase. Those preferring completed firearms should consider factory-built alternatives rather than 80% kits.
What's in the box?
The package contains three 80% complete polymer frames and one precision machining jig with all necessary drill bits and templates. Each frame includes pre-molded grip texture and rail sections requiring no additional finishing. The jig features stainless steel drill bushings rated for 500+ cycles according to lubrication studies. No slide parts or fire control components are included beyond the raw frames.
Is the Polymer80 PF940v2 3-pack worth it at $610.99?
At $203.66 per frame with jig, the kit offers value for builders requiring multiple platforms or spares. Comparable single frames retail for $149-$179 without jigs, making the bundle 18-31% cheaper per unit. The discontinued status increases collectibility but reduces warranty support options. For builders needing only one frame, the Polymer80 LR-308 may provide better per-unit value for rifle applications.
