Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit (Glock® 17/22/24/31/34/35 Compatible) - polymer 80
About this product
What is the Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit? It is a CNC‑machined polymer lower receiver and complete alignment jig for Glock® 17/22/24/31/34/35 platforms, sold as an 80% component for builders. This kit delivers a ready‑to‑finish frame that meets Glock dimensions within .15 mm tolerance, allowing a straightforward milling process for experienced DIYers.
What is the Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit used for?
It is used to fabricate a functional Glock‑compatible full‑size lower receiver at home. The kit includes the 80% frame, a precision stainless‑steel jig, and sanding pads so you can complete the final 20% of material removal in under 30 minutes with a standard bench grinder.
How does the Polymer80 PF940v2™ compare to the Glock 17 Gen5 lower?
The PF940v2™ is lighter and cheaper than a factory Glock 17 Gen5 lower, weighing 13.2 oz versus the Gen5’s 22 oz, and costing $220.99 compared to a $580 retail lower. The polymer construction reduces weight by 40 % while maintaining comparable strength, but it lacks the factory‑finished internal polish of the Gen5.
What does it weigh and what are the dimensions?
The frame weighs 13.2 oz (374 g) and measures 7.5 in × 1.3 in × 0.9 in (190 mm × 33 mm × 23 mm) overall. Its grip length matches the Glock 17/22 spec of 5.04 in (128 mm), ensuring compatible magazine insertion without modification.
Who is this NOT for?
This kit is not for beginners with no machining experience. The 80% status requires you to remove the final material, which involves a drill press or grinder and an understanding of legal compliance; novices may find the process time‑consuming and error‑prone.
What's in the box?
The package contains one polymer lower receiver, one stainless‑steel alignment jig, three sanding pads (coarse, medium, fine), a 1/4‑in drill bit, and a printed PDF with step‑by‑step instructions. All components are packaged in a recyclable 12 × 9 × 2 in (305 mm × 229 mm × 51 mm) box.
Is the Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit worth it at $220.99?
Yes, it offers a solid value for shooters who need a custom Glock frame without paying premium OEM prices. At $220.99 you save roughly $359 versus a new factory lower, and the weight reduction improves handling. However, remember the additional $30‑$50 cost for finishing tools and the legal responsibility of 80% part fabrication.
