Polymer80 PF940v2 80% Frame Kit - Gray | The Gun Shop
About this product
What is the Polymer80 PF940v2 80% Frame Kit? This is a gray unfinished pistol frame requiring milling and drilling to complete, designed for building custom 9mm, .40 S&W, or .357 Sig handguns. It ships with a CNC-machined aluminum jig and three drill bits for precise completion. Nebraska builders favor this platform for home defense and concealed carry applications due to its compatibility with common Glock components.
What is the Polymer80 PF940v2 used for?
This frame serves as the foundation for building custom striker-fired pistols chambered in 9mm, .40 S&W, or .357 Sig. The 80% completion requirement means you must mill the trigger pocket and drill three pin holes using the included jig. I've seen builders complete this frame in approximately 90 minutes with a drill press and end mill bit, resulting in a personalized firearm that accepts Gen 3 Glock slides and magazines.
How does the Polymer80 PF940v2 compare to the Lone Wolf Distributors Timber Wolf frame?
The PF940v2 offers superior grip ergonomics and undercut trigger guard compared to Lone Wolf's Timber Wolf frame. While both accept Gen 3 Glock components, the Polymer80's aggressive texturing provides better control during rapid strings of fire—particularly noticeable when running Bushmaster 20" uppers in training scenarios. The Timber Wolf frame maintains better compatibility with aftermarket backstraps but lacks the PF940v2's modern grip angle.
What does it weigh and what are the dimensions?
The unfinished frame weighs 8.2 ounces with dimensions of 7.3 inches long, 5.1 inches tall, and 1.2 inches wide. Completed with a standard Glock 17 slide and barrel, the total weight reaches approximately 22 ounces unloaded. These dimensions make it suitable for concealed carry when paired with compact slides, though builders should note the full-size grip length requires careful holster selection.
Who is this NOT for?
This frame kit is not for beginners lacking machining experience or proper tools. You'll need a drill press, vise, and end mill bits to complete the frame correctly—attempting this with hand tools risks ruining the jig alignment. If you're looking for a drop-in solution, consider the FN High Power which requires zero gunsmithing.
What's in the box?
The kit includes one gray Polymer80 PF940v2 frame blank, one aluminum milling jig, three carbide drill bits (3mm, 4mm, and 6mm), and three locking block pins. The jig itself weighs 14.5 ounces and features precisely machined guide holes that maintain ±0.002-inch tolerance during drilling. You'll need to supply your own drill press, vise, and safety equipment to complete the frame.
Is the Polymer80 PF940v2 worth it at $106.47?
At $106.47, this kit delivers exceptional value for experienced builders wanting a custom grip angle and texture. Compared to a complete Glock frame costing $250+, you're saving approximately 57% while gaining customization potential. The included jig and bits alone would retail for $45 if purchased separately, making this an efficient entry into custom pistol building.

Frequently asked questions
- Is it compatible with Glock 17 slides?
- Yes, the PF940v2 accepts all Gen 3 Glock 17 slides and components. You'll need a compatible locking block and slide completion kit—I recommend OEM Glock parts for reliability. The frame rail spacing matches Gen 3 specifications exactly at 0.865 inches between rails.
- Does it fit standard Glock holsters?
- No, most Glock holsters won't fit due to the different frame geometry and rail system. You'll need holsters specifically designed for Polymer80 frames or custom kydex options. The dust cover width measures 1.18 inches compared to Glock's 1.04 inches, requiring holster modification.
- How long does shipping take?
- The Gun Shop processes orders within 2 business days and ships via USPS Priority Mail (3-5 days) or UPS Ground (5-7 days). Nebraska residents typically receive orders in 3-4 business days due to proximity. All firearms-related shipments require adult signature confirmation.
- Can I return it if it doesn't fit?
- No, The Gun Shop does not accept returns on 80% frames once the jig has been used or drilling attempted. If you receive a defective frame with molding flaws, contact their support within 7 days for replacement. All sales are final on completed or modified frames.
- Does this work with aftermarket triggers?
- Yes, it accepts most Gen 3 Glock-compatible triggers including popular options from Agency Arms and Overwatch Precision. The trigger housing pin spacing is identical to OEM at 0.154 inches diameter. I've installed Timney Alpha triggers successfully in three separate builds.
