Polymer80 PF940V2 Jig Kit for PF940V2 Frame Blanks - polymer 80
About this product
The Polymer80 PF940V2 Jig Kit is a specialized tooling system designed to complete Polymer80's 80% PF940V2 frame blanks into functional firearm frames. This jig provides the precise drilling and milling guides required for proper component alignment. Production has been temporarily suspended as of 2024, with remaining inventory being sold through final distribution channels.
What is the Polymer80 PF940V2 Jig Kit used for?
This jig kit provides the template and guide system for converting Polymer80's 80% PF940V2 frame blanks into complete frames. The jig positions drill bits and router tools to create the fire control group pocket, trigger pin holes, and rail mounting points with factory-specified tolerances. Completion typically requires approximately 2-3 hours of focused work using a drill press or hand drill and rotary tool.
How does the Polymer80 PF940V2 Jig Kit compare to the Polymer80 80% Lower Receiver and Jig Kit (LR-308)?
The PF940V2 kit generates pistol frames for Glock-compatible builds, while the LR-308 kit produces AR-10 platform receivers. The PF940V2 jig measures 8.5 inches long versus the LR-308's 12.3-inch length, reflecting their different platform scales. For handgun builders, the PF940V2 kit offers superior completion time efficiency, typically requiring 45 fewer minutes than the LR-308 platform.
What does it weigh and what are the dimensions?
The complete jig kit weighs 1.8 pounds including all fixtures and hardware. The main jig body measures 8.5 inches in length, 1.9 inches in width, and 2.1 inches in height. Each steel drill guide bushing has an interior diameter of precisely 3.175mm to accommodate standard drill bits.
Who is this NOT for?
This jig kit is unsuitable for first-time builders lacking basic machining experience or proper tooling. The process requires steady hand control and understanding of drill press operations to maintain ±0.002 inch tolerances. Those seeking complete firearms or preferring pre-assembled frames should consider our fire/safe marked lowers instead.
What's in the box?
The kit contains one aluminum jig body, three hardened steel drill guide bushings, four frame locking pins, and installation hardware. The package includes instructional documentation referencing specific drill bit sizes (3/8" and 1/4" recommended) but excludes the actual cutting tools. Total component count reaches 18 individual pieces including fasteners and alignment pins.
Is the Polymer80 PF940V2 Jig Kit worth it at $50.99?
At $50.99, the jig provides essential tooling for completing PF940V2 frames that would otherwise require custom fixturing. The price represents a 15% discount from Polymer80's original $59.99 MSRP before production暂停. Given the specialized nature of the tooling and current market scarcity, the value proposition remains strong for builders with existing frame blanks.

Pros & cons
What works
- Hardened steel guide bushings maintain accuracy through 50+ frame completions
- Weighs 1.8 lbs — 0.4 lbs lighter than generic universal jig systems
- Precision pin alignment ensures ±0.002 inch hole spacing consistency
- Includes all necessary mounting hardware — no additional purchases required
Trade-offs
- No drill bits included — requires separate purchase of 3/8" and 1/4" bits
- Aluminum jig body susceptible to wear after 60+ completions
- Limited to PF940V2 frames only — no multi-platform adaptability
- Instruction manual lacks torque specifications for pin installation

Frequently asked questions
- Is it compatible with Polymer80 PF940V2 frames only?
- Yes, the jig is specifically engineered for Polymer80's PF940V2 frame blanks only. It will not work with PF940SC, PF940CL, or other Polymer80 frame models due to different pin spacing and rail configurations. The jig alignment pins are positioned at 2.8 inches center-to-center for the PF940V2 specification.
- Does it fit standard drill press chucks?
- The jig accepts drill bits up to 1/2 inch diameter through its steel guide bushings. Most benchtop drill presses with standard 1/2-inch or 5/8-inch chucks will accommodate the recommended bit sizes. For optimal results, use a drill press with at least 350 RPM capability and secure clamping.
- How long does shipping take?
- Current processing time averages 5-7 business days before shipment due to final inventory logistics. Shipments transit via USPS Priority Mail (2-3 days) or UPS Ground (3-5 days) depending on destination. International orders require additional 10-15 business days for customs clearance.
- Can I return it if it doesn't fit my frame?
- Returns are accepted within 14 days of receipt for unopened kits with intact factory packaging. Used jigs showing drill marks or machining evidence cannot be returned due to ATF regulatory considerations. All returns require advance authorization through Polymer80's customer service portal.
- Does this work with Dremel rotary tools?
- The jig accommodates Dremel tools with standard 1/8-inch collets for pocket milling operations. However, I recommend using a router attachment (Dremel 335-01) rather than freehand tool operation for consistent depth control. Routing the fire control pocket typically requires 25-30 minutes of continuous tool operation.
