About this product
What is the Polymer80 PF940SC™ 80% Pistol Frame? It's an unfinished polymer frame designed for building custom Glock 26/27 pistols, featuring an 18-degree grip angle and reinforced construction. This frame requires machining to complete and ships with essential rail components. It's engineered for shooters who want full control over their carry pistol's ergonomics and trigger system.
What is the Polymer80 PF940SC™ 80% Pistol Frame used for?
This frame is used for building custom Glock 26 or 27 pistols from the ground up. You'll need to complete the 80% machining process, then install your choice of slide, barrel, and trigger components. The frame accepts all Gen3 Glock 26/27 parts and maintains magazine compatibility with OEM and aftermarket options.
How does the Polymer80 PF940SC™ compare to the OEM Glock 26 frame?
The PF940SC outperforms the factory Glock 26 frame in ergonomics but requires significant finishing work. It features an 18-degree grip angle versus Glock's 22 degrees, providing better recoil control and faster follow-up shots. However, unlike the drop-in ready OEM frame, this requires approximately 2-3 hours of machining and fitting. The extended beavertail and undercut trigger guard make it superior for shooters with larger hands.
What does it weigh and what are the dimensions?
The unfinished frame weighs 5.8 ounces and measures 6.2 inches long by 4.3 inches tall. When completed with a standard Glock 26 slide assembly, total weight reaches approximately 21 ounces. The frame's rail-to-rail width is 1.0 inch, maintaining compatibility with most holsters designed for compact Glocks.
Who is this NOT for?
This frame is not for beginners or those without access to a drill press and basic gunsmithing tools. If you want a ready-to-shoot pistol immediately, buy a complete Glock 26 instead. The machining process requires precision—one misdrilled hole can ruin the $182 frame. It's also not ideal for those who prefer the factory Glock grip angle or want a completely stock firearm.
What's in the box?
You receive the 80% polymer frame, locking block rail system, and rear rail module—three components total. No jig, drill bits, or completion parts are included. You'll need to purchase the PF940SC™ jig separately, plus a G26 parts kit to finish the build.
Is the Polymer80 PF940SC™ worth it at $181.92?
At $181.92, it's worth it only if you value custom ergonomics and enjoy the building process. A complete OEM Glock 26 frame costs roughly $250-$300, but requires no machining. The price becomes justified when you consider the improved grip angle, undercut trigger guard, and personalization potential. For trigger-focused builds, pair this with our 3.5lb Modified Cut Nub Connector for a crisp break.

- Compatible with all Gen3 Glock 26/27 parts—no proprietary components required
Trade-offs
- No jig included—adds $45-$60 to complete the machining setup
- Requires precise drilling—tolerance of ±0.005" for trigger pin holes, beginners will struggle
- No stippling or texturing—adds $50-$100 for professional stippling or DIY time
- Not California compliant—80% frames cannot be shipped to restricted states

Frequently asked questions
- Is it compatible with Glock 26 magazines?
- Yes, it maintains full compatibility with OEM Glock 26 magazines and aftermarket options. The magazine well dimensions match the factory spec exactly. Tested with 10-round, 12-round, and 15-round extended magazines—all function flawlessly.
- Does it fit standard Glock 26 holsters?
- Most holsters designed for Glock 26 will work, but check clearance for the extended beavertail. The frame width is identical to OEM at 1.0 inch. We recommend testing with your specific holster—some tight-fitting models may require slight modification.
- How long does shipping take?
- Orders ship within 1 business day via USPS Priority Mail. Continental US delivery typically takes 2-3 business days. International shipments require 7-14 days depending on customs processing. Tracking is provided within 4 hours of shipment.
- Can I return it if I mess up the machining?
- No returns are accepted once machining has begun or the frame is altered. The 80% nature means it's yours once you start work. We recommend practicing on cheaper polymer blanks first—one misdrilled hole voids all return eligibility immediately.
- Does this work with aftermarket trigger kits?
- Yes, it works with most aftermarket Glock 26 trigger kits including Apex, Overwatch, and our own GLOCK FRT drop-in units. The trigger housing dimensions match Gen3 specifications exactly.
