Polymer80 PF940V2 Jig Kit for PF940V2 Frame Blanks
Pros & cons
What works
- Lifetime warranty coverage—no expiration on manufacturing defects
- 1.8 lb total weight provides stability during drilling operations
- Hardened steel bushings rated for 25+ frame completions
- ±0.002" hole alignment tolerance ensures proper pin fit
Trade-offs
- No frame included—requires separate $120-150 PF940V2 blank purchase
- No drill bits or end mill included—adds $40-60 tooling cost
- Aluminum jig body susceptible to damage if dropped on hard surfaces
- Specific to PF940V2 only—no multi-platform compatibility

About this product
The Polymer80 PF940V2 Jig Kit is a dedicated tooling system designed specifically for completing PF940V2 80% frame blanks into functional Glock 17/22-compatible pistol frames. This jig-only kit provides the precision alignment and drilling guidance required for proper frame completion without including the actual frame blank. It comes with a lifetime warranty and is engineered for perfect fit with Polymer80's PF940V2 platform.
What is the Polymer80 PF940V2 Jig Kit used for?
This jig kit is used for precisely drilling and milling the necessary holes and cavities in Polymer80 PF940V2 80% frame blanks to create functional pistol frames compatible with Glock 17/22 components. The jig provides exact alignment for the three critical pin holes and rail sections, ensuring proper geometry for reliable function. It requires basic workshop tools including a drill press or hand drill and end mill for completion.
How does the Polymer80 PF940V2 Jig Kit compare to the 80% AR-15 Easy Jig® Gen 1?
The Polymer80 PF940V2 Jig Kit provides superior polymer frame-specific tooling compared to the more universal 80% AR-15 Easy Jig® Gen 1 designed primarily for aluminum AR lowers. While the Easy Jig handles multiple platforms, this dedicated jig offers tighter tolerances specifically for PF940V2 frames, resulting in more precise hole alignment and better frame-to-slide fit. The Polymer80 jig is better for Glock-platform builds, while the Easy Jig excels at AR-15 applications.
What does it weigh and what are the dimensions?
The complete jig kit weighs 1.8 pounds (816 grams) and measures 8.5 x 6.25 x 3 inches (216 x 159 x 76 mm) when assembled. The aluminum jig body itself accounts for 1.2 pounds of the total weight, providing substantial mass for vibration damping during drilling operations. These dimensions allow it to fit comfortably in a standard bench vise while providing adequate clearance for drill and milling operations.
Who is this NOT for?
This jig kit is not for builders seeking a complete solution that includes the frame blank itself—you'll need to purchase the PF940V2 frame separately. It's also unsuitable for those working with other platform frames like AR-15 or .308 billet lowers, as the tooling is specifically designed for Polymer80's PF940V2 geometry. Beginners without access to basic machining tools should consider professional gunsmithing services instead.
What's in the box?
The kit includes the main aluminum jig body, three drill bushings for the trigger, locking block, and rear rail pin holes, one milling guide for the recoil spring channel, and all necessary hardware for assembly. You get exactly 4 precision-machined guide components manufactured from hardened steel to withstand repeated use. The package does not include drill bits, end mills, or the actual frame blank—those must be sourced separately.
Is the Polymer80 PF940V2 Jig Kit worth it at $50.99?
At $50.99, this jig kit provides excellent value for serious builders planning multiple PF940V2 frame completions. The lifetime warranty ensures long-term usability, and the precision tooling saves hours of measurement and setup time compared to makeshift jigs. For builders following proper jig alignment procedures, this kit pays for itself after just two frame completions by eliminating costly mistakes.

Frequently asked questions
- Is it compatible with PF940SC frames?
- No, this jig is specifically designed for PF940V2 full-size frames only. The PF940SC compact frames require a different jig due to different pin spacing and rail geometry. Attempting to use this jig on a PF940SC frame will result in misaligned holes and potentially ruin the frame.
- Does it work with aftermarket drill bits?
- Yes, the hardened steel bushings work with standard 3/8" drill bits from any quality tool manufacturer. However, I recommend using cobalt or titanium nitride coated bits for cleaner holes and longer bushing life. The bushings have a 0.375" inner diameter tolerance held to ±0.001".
- How many frames can I complete with one jig?
- The hardened steel bushings are rated for approximately 20-25 frame completions before showing significant wear. The aluminum jig body itself can last indefinitely with proper care. For high-volume builders, Polymer80 offers replacement bushing sets separately.
- Does this include the frame locking block?
- No, this is a jig-only kit—it contains only the tooling guides for completing the frame. The locking block, rails, pins, and all other frame components must be purchased separately. You'll need a complete parts kit along with the 80% frame blank.
