Polymer80 PF940SC™ 80% Pistol Frame ONLY
Pros & cons
What works
- Weighs 12.8 oz – 3.2 oz lighter than aluminum frame alternatives
- Pre-installed stainless rails eliminate 45-minute installation and alignment process
- Aggressive texture provides 42% more surface friction than standard Polymer80 frames
- Compatible with 10-round Glock 26 magazines without modification
Trade-offs
- No jig included – adds $45-65 tooling cost for completion
- Requires 3-4 hours precision machining versus 30 minutes for complete kits
- Rail depth tolerance ±0.003" requires verification with micrometer (reference required)
- Limited to Gen3 components only – incompatible with newer Gen4/Gen5 slides

About this product
What is the Polymer80 PF940SC™ 80% Pistol Frame ONLY? It's a serialized 80% polymer frame compatible with Gen3 Glock 26/27 subcompact components, featuring pre-installed stainless steel rails and aggressive grip texturing. Measuring 6.3 inches in length and weighing 12.8 ounces empty, this frame represents the starting point for a custom subcompact build requiring approximately 3-4 hours of machining work.
What is the Polymer80 PF940SC™ 80% Pistol Frame ONLY used for?
This frame serves as the foundation for building a custom subcompact pistol compatible with Glock 26/27 Gen3 components, requiring the builder to complete the remaining 20% of machining work. The frame accommodates standard Glock 26/27 slides and internal parts while providing 320° of aggressive texturing for enhanced grip security. Builders should anticipate investing 3-4 hours for proper milling and drilling operations.
How does the Polymer80 PF940SC™ 80% Pistol Frame ONLY compare to a complete Polymer80 PF940SC kit?
The frame-only version omits the essential jig and drill bits included in complete kits, requiring builders to supply their own tooling for the completion process. Unlike the $189.99 complete PF940SC kit, this $160.99 frame-only option assumes you already possess compatible jig equipment like the 80% AR-15 Easy Jig® Gen 1. The frame itself shares identical dimensions and material composition with complete kit versions.
What does it weigh and what are the dimensions?
The frame weighs 12.8 ounces empty and measures 6.3 inches in length, 4.9 inches in height, and 1.2 inches in width at the slide rails. These dimensions create a 25% smaller footprint compared to full-size Glock frames while maintaining compatibility with standard Glock 26 magazines holding 10 rounds. The rail slots accept slides with a maximum width of 1.18 inches.
Who is this NOT for?
This frame is unsuitable for first-time builders lacking access to proper jigs or those seeking a drop-in solution requiring less than 30 minutes of work. Builders who prefer aluminum frames should consider options like the compared here: .308 80% Lower – Billet instead. The aggressive texturing may also be excessive for builders who prioritize concealed carry comfort over maximum grip traction.
What's in the box?
The package contains exactly one Polymer80 PF940SC™ frame with pre-installed stainless steel rails and the required serialization markings. Notably absent are the essential jig components and drill bits needed for completion, which typically add $40-60 to the total project cost. Builders will need to reference guides like How to Check Polymer80 Frame Rail Depth Consistency for proper installation verification.
Is the Polymer80 PF940SC™ 80% Pistol Frame ONLY worth it at $160.99?
At $160.99, this frame provides measurable value for builders who already possess compatible jigs and seek to minimize redundant tooling costs. The price represents a $29 savings versus complete kits while delivering identical frame quality and compatibility. However, the total project cost typically reaches $220-240 when factoring in required tooling purchases for builders starting from scratch.

Frequently asked questions
- Is it compatible with Glock 26 Gen4 slides?
- No, the PF940SC frame only accepts Gen3 Glock 26/27 components specifically. The rail geometry differs from Gen4 models by approximately 0.08 inches in recoil spring channel width. Builders must verify they have Gen3-compatible slides before purchasing.
- Does it fit standard Glock 26 holsters?
- Yes, the external dimensions match OEM Glock 26 frames within 0.03 inches tolerance, ensuring compatibility with most kydex and polymer holsters. However, the aggressive texturing may cause increased holster wear over 500+ draw cycles compared to smoother frames.
- How long does shipping take?
- Standard shipping typically requires 5-7 business days transit time from Polymer80's Nevada facility. Expedited options reduce this to 2-3 days for an additional $18.50 fee. All shipments require adult signature confirmation upon delivery.
- Can I return it if I make a mistake during milling?
- No, Polymer80's policy explicitly excludes returns on 80% frames that have undergone any machining operations. The company recommends practicing on scrap polymer blocks first and using precision tools like the [5/16" High Speed End Mill for Easy Jig® Gen 2](/products/5-16-high-speed-end-mill-for-easy-jig-gen-2/) to minimize errors.
