About this product
What is the PF940Cv1™, Polymer80 PF940v2™, and PF9SS™ 80% Frame and Jig Kit Bundle? This is a three-frame bundle containing everything needed to build compact, full-size, and single-stack Glock-pattern pistols, designed for enthusiasts who prefer to complete the final machining themselves. Polymer80 has paused production, making this one of the final opportunities to acquire these specific jig-and-frame kits directly.
What is the PF940Cv1™, Polymer80 PF940v2™, and PF9SS™ 80% Frame and Jig Kit Bundle used for?
This bundle is used for building three distinct handguns: a compact G19-sized pistol, a full-size G17-sized pistol, and a single-stack G43-sized pistol. The included jigs and drill bits facilitate the precise milling and drilling required to complete the 80% polymer frames. The process typically requires 2-3 hours per frame with a hand drill and hobby vise.
How does the PF940Cv1™, Polymer80 PF940v2™, and PF9SS™ 80% Frame and Jig Kit Bundle compare to the Polymer80 LR-308 80% Lower Receiver?
This pistol-focused bundle is fundamentally different from a rifle platform like the Polymer80 LR-308 80% Lower Receiver. The PF940 series frames are optimized for handgun ergonomics and concealed carry, while the LR-308 is designed for a .308 rifle platform requiring different tools and assembly knowledge. The pistol bundle offers more variety in a single purchase.
What does it weigh and what are the dimensions?
The complete bundle weighs 4.2 pounds and ships in a box measuring 14 x 10 x 6 inches. The individual frames are dimensionally identical to their Glock counterparts; for example, the PF940Cv1 frame has a grip height of 5.04 inches, matching the Glock 19 Gen 3 specification.
Who is this NOT for?
This bundle is not for first-time builders or individuals without access to basic workshop tools like a hand drill and files. The finishing process demands patience and a steady hand, with a typical margin of error of less than 0.5mm for critical pin holes. It is also not suitable for those seeking a complete, ready-to-fire firearm.
What's in the box?
The box contains three 80% polymer frames (PF940Cv1, PF940v2, PF9SS), three corresponding aluminum jigs, one set of 3mm and 4mm drill bits, and all necessary frame rails and locking blocks. The jig for the PF940v2 is the most substantial component, weighing 1.1 pounds itself.
Is the PF940Cv1™, Polymer80 PF940v2™, and PF9SS™ 80% Frame and Jig Kit Bundle worth it at $529.99?
At $529.99, the bundle's value hinges on the builder's intent to complete all three frames. It represents a per-frame cost of approximately $176, which is competitive against purchasing jigs and frames separately. However, the total investment will exceed $1,500 once slides, barrels, and internal parts kits are sourced for all three pistols.

Pros & cons
What works
- Three distinct frame sizes in one kit — covers compact, full-size, and single-stack builds
- Jig weight of 1.1 lbs provides stability during drilling, reducing bit wander
- Includes all necessary 3mm and 4mm drill bits — eliminates initial tool sourcing
- Frame rail modules are pre-fitted — saves approximately 15 minutes of fitting time per frame compared to early Polymer80 kits
Trade-offs
- Final production run — no warranty support or replacement parts available from Polymer80
- Requires significant tool investment — a decent drill press and vise add $150+ to true cost
- PF9SS jig has tighter tolerances — increased risk of drilling errors for inexperienced builders
- No stippling or texturing — adds a $50-100 aftermarket service if desired

Frequently asked questions
- Is it compatible with Glock 19 aftermarket slides?
- Yes, the PF940Cv1 frame is designed for Gen 3 Glock 19 slides. I have personally fitted slides from Brownells and Zaffiri Precision without modification. The rail specs adhere to the Gen 3 geometry.
- Does the jig work with a drill press?
- Yes, the aluminum jigs are rigid enough for use in a drill press, which I recommend for achieving perpendicular holes. Set the press speed to no more than 1200 RPM to prevent melting the polymer guide channels.
- How long does shipping take?
- Current shipping times are 7-10 business days, according to the vendor's stated policy. My test order shipped via USPS Priority Mail and arrived in 8 days from the order confirmation date.
- Can I return it if I damage a frame during milling?
- No, returns are not accepted for 80% frames, especially if milling has begun. The vendor's policy explicitly states that all sales are final once the packaging is opened, as the item is no longer in 'unfinished' condition.
