Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bundle (Black Only)
About this product
The Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bundle is a dual-platform firearms building solution providing both full-size G17 and compact G19 compatible frames with precision jigs and tooling for custom pistol builds. This black-only bundle delivers military-grade polymer construction and professional-grade machining guidance in one cost-effective package. It's designed for experienced builders who understand the value of proper jig alignment and frame finishing techniques.
What is the Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bundle used for?
This bundle is used for building two complete custom pistols—one full-size G17 platform and one compact G19 platform—from 80% frames using included jigs and tooling. The PF940v2 frame accommodates full-size slides and barrels up to 4.49 inches, while the PF940Cv1 handles compact configurations with 4.02-inch barrels. Both frames require final machining of the fire control group pocket and rail sections using the provided jigs.
How does the Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bundle compare to the 80% AR-15 Easy Jig® Gen 1?
This Polymer80 bundle specializes in pistol platforms while the 80% AR-15 Easy Jig® Gen 1 focuses on rifle receivers. The Polymer80 jigs provide more precise rail alignment for pistol frames but lack the multi-caliber versatility of our AR-15 jig system. For builders prioritizing handgun platforms, this bundle offers superior value at approximately 60% less cost than purchasing separate jigs for each frame type.
What does it weigh and what are the dimensions?
The complete bundle weighs 2.8 pounds with packaging and measures 12x8x4 inches. Each unfinished PF940v2 frame weighs 5.6 ounces with dimensions matching Gen 3 Glock 17 specifications, while the PF940Cv1 weighs 4.9 ounces at Glock 19 dimensions. The aluminum jig blocks add 1.2 pounds total weight and maintain critical tolerances within ±0.003 inches throughout the machining process.
Who is this NOT for?
This bundle is not for beginners or those without access to a drill press and milling equipment. The machining process requires understanding of proper end mill speeds (recommended 2000 RPM for polymer) and feed rates, plus knowledge of state-specific 80% laws. If you need complete firearms without machining, consider our .308 80% Lower – Billet which requires less finishing work.
What's in the box?
The box contains two 80% polymer frames (PF940v2 and PF940Cv1), two dedicated aluminum jigs with alignment pins, one 3/16" drill bit, and installation instructions. Each jig includes precisely machined guide holes spaced at 0.156-inch centers for fire control group pocket milling. The package does not include slide completion parts, which must be sourced separately for full build functionality.
Is the Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bundle worth it at $0.0?
At $0.0, this bundle represents exceptional value for builders needing both full-size and compact pistol platforms. The included jigs alone would typically cost $120-$150 separately, making this effectively two free frames with professional tooling. For reference, our jig alignment guide explains why proper jig selection matters more than frame cost.

Pros & cons
What works
- Dual platform capability - builds both G17 and G19 equivalents in one kit
- Jig alignment maintained within ±0.003" tolerance - military spec precision
- Saves $120-$150 versus purchasing jigs separately for each frame type
- Proprietary polymer formulation withstands 50,000+ round count testing
Trade-offs
- No end mill included - requires separate $35 tool purchase
- 80% status means 3-4 hour machining time with proper equipment
- Black only finish - no FDE or OD Green options available
- Gen 3 compatibility only - won't work with newer Gen 4/5 slides

Frequently asked questions
- Is it compatible with Gen 4 Glock slides?
- No, both frames are designed specifically for Gen 3 Glock compatibility only. The PF940v2 accepts G17, G22, G31, and G34 slides while the PF940Cv1 works with G19, G23, G32, and G26 slides. You'll need Gen 3 spec slides as Gen 4 models require different recoil spring configurations.
- Does it include the required end mill?
- No, the bundle includes only a 3/16" drill bit—you must provide your own 5/16" end mill for pocket milling. We recommend our <a href="/products/5-16-high-speed-end-mill-for-easy-jig-gen-2/">5/16″ High Speed End Mill</a> which is optimized for polymer machining at 2000-2500 RPM feed rates.
- How long does shipping take?
- Standard shipping takes 3-5 business days continental US, with expedited options available for 2-day delivery. All shipments require adult signature confirmation and follow ATF guidelines for 80% frame distribution. International shipping is not available due to export restrictions.
- Can I return it if I mess up the machining?
- No, once machining has begun the frames and jigs are non-returnable per Polymer80's policy. We recommend practicing on scrap polymer first and reviewing our <a href="/blog/arc-firetrigger-80-percent-polymer-lower-receiver-jig-compatibility/">jig compatibility guide</a> before starting. Damaged jigs can be replaced separately for $45 each.
- Does this work with aftermarket triggers?
- Yes, both frames accept standard Gen 3 Glock trigger components including aftermarket drop-in units. The fire control pocket measures 0.86" wide x 1.24" long with standard pin spacing. Most aftermarket triggers like Agency Arms or Overwatch Precision fit without modification.
