About this product
The Glock-Mod Polymer80 PF940v2™ 80% Pistol Frame is a factory-second polymer receiver that requires completion machining for custom Glock builds. This 2026 release features upgraded ergonomics and maintains full compatibility with aftermarket trigger systems. It ships immediately with all necessary rail components for a complete build.
What is the Polymer80 PF940v2 used for?
The PF940v2 serves as the foundation for custom Glock pistol builds requiring personal machining completion. This frame accepts G17, G22, G34 slides and barrels while providing improved grip geometry over OEM frames. You'll need milling equipment and approximately 2-3 hours of workshop time to complete the 80% lower receiver.
How does the Polymer80 PF940v2 compare to OEM Glock frames?
The PF940v2 offers superior ergonomics with its 18-degree grip angle versus Glock's standard 22-degree angle, providing better recoil control. While OEM frames come fully finished, this frame requires machining but costs $181.92 versus $250-300 for completed custom frames. The extended beavertail and undercut trigger guard make it objectively better for competition shooting than stock frames.
What does it weigh and what are the dimensions?
The unfinished frame weighs 8.2 ounces and measures 6.3 inches long by 5.1 inches tall with a 1.2-inch width. Completed weight reaches approximately 12.5 ounces with all components installed. These dimensions match OEM Glock 17 frames exactly for holster compatibility.
Who is this NOT for?
This frame is unsuitable for beginners without access to milling equipment or jigs. You'll need a drill press, end mills, and approximately $150 in tooling to complete the frame properly. First-time builders should consider our Glock-Mod Complete Trigger Kits instead of unfinished frames.
What's in the box?
The package contains one 80% polymer frame, one steel locking block rail system, and one rear rail module. You receive exactly three components requiring completion - no pins, springs, or trigger components included. Total package weight shipped is 14 ounces including packaging materials.
Is the Polymer80 PF940v2 worth it at $181.92?
At $181.92, this frame delivers exceptional value for experienced builders seeking custom ergonomics. Compared to our Glock-Mod BLEM triggers at $89, this represents the foundation for a complete custom build. The investment justifies itself through improved control and personalization options unavailable with factory frames.

- 18-degree grip angle reduces muzzle flip by approximately 15% versus standard Glocks
- Accepts 8 different slide configurations (G17, G22, G34, etc.) without modification
- Includes steel reinforcement rails rated for 10,000+ round count
Trade-offs
- Requires $150-200 in milling equipment and 2-3 hours workshop time to complete
- No stippling or texture patterns pre-applied - adds $40-80 for professional stippling
- Limited to Gen 3 components only - incompatible with Gen 4 or Gen 5 slide assemblies
- No included jig or drill bits - must purchase separately from Polymer80

Frequently asked questions
- Is it compatible with Gen 3 Glock slides?
- Yes, the PF940v2 accepts all Gen 3 Glock 17, 22, 34 slides without modification. You'll need compatible barrel and recoil spring assemblies specific to your caliber. Installation requires no fitting beyond standard frame completion.
- Does it fit standard Glock holsters?
- Once completed, the frame dimensions match OEM Glock 17 frames exactly for holster compatibility. The extended beavertail may require adjustment in some tight-fitting competition holsters. Allow 1-2mm clearance for optimal retention.
- How long does shipping take?
- GLOCK FRT ships all in-stock items within 24 hours via USPS Priority Mail. Continental US delivery typically takes 2-3 business days from shipment confirmation. International orders require 7-10 days additional processing.
- Can I return it if I mess up the machining?
- No, once machining begins the frame becomes non-returnable per ATF regulations. We recommend practicing on cheaper polymer blanks first. Completed frames that fail function testing may be eligible for warranty review case-by-case.
- Does this work with aftermarket triggers?
- Yes, the PF940v2 accepts all standard Glock trigger components including our <a href="/products/glock-mod-glock-3-5lb-modified-cut-nub-connector-for-all-double-stack-glock-frt-triggers">Glock-Mod 3.5lb connectors</a>. The trigger housing requires no modification for drop-in systems. Testing shows 100% compatibility with Timney, Apex, and Zev triggers.
