About this product
The PF940Cv1™, Polymer80 PF940v2™, and PF9SS™ 80% Frame and Jig Kit Bundle is a discontinued three-frame combo that allows you to construct a compact G19 clone, a full-size G17 clone, and a subcompact G43 clone from polymer blanks. This is our final clearance of original Polymer80 inventory, packaged as a single SKU for builders who want to stock multiple platforms. Given the changing regulatory landscape, we now strongly recommend using cryptocurrency for these transactions to protect your privacy.
What is this 80% frame bundle used for?
This bundle is used to legally manufacture three distinct, unserialized pistol frames at home using common drill press or hand tools. It provides the core structural components for building a compact-duty pistol (PF940Cv1), a full-size duty pistol (PF940v2), and a concealed-carry pistol (PF9SS). Each frame comes with a dedicated, color-coded aluminum jig that guides the milling of the fire control pocket and drilling of three critical pin holes.
How does this bundle compare to a single .308 80% Lower – Billet?
This pistol bundle offers three platforms for the price comparable to a single high-end rifle lower like the <.308 80% Lower – Billet> (/products/308-80-lower-billet-polymer-80/), which costs $249.99 alone. The rifle lower is superior for constructing a precision .308 AR-10, but this bundle provides more build diversity and is a better value for someone focused exclusively on handguns who wants to avoid single-platform lock-in.
What does it weigh and what are the dimensions?
The complete bundle weighs 2,470 grams (87.1 oz), which includes three polymer frames and three aluminum jigs. Each individual frame has different dimensions: the PF940Cv1 measures 180mm long, 30mm wide, and 125mm tall; the PF940v2 is 195mm long; and the PF9SS is 155mm long. The shipping box measures 400mm x 300mm x 150mm.
Who is this NOT for?
This bundle is not for first-time builders or anyone uncomfortable with performing precise milling operations on polymer substrates. The required front rail module installation on these frames has a 0.005-inch tolerance window, and misalignment will cause slide binding. It is also not suitable for buyers in jurisdictions that prohibit possession of unserialized frames, or for those seeking a pre-finished, stippled grip frame ready for immediate assembly.
What's in the box?
You receive three distinct items: one PF940Cv1 compact frame (79% finished, 450 grams), one PF940v2 full-size frame (79% finished, 490 grams), and one PF9SS subcompact frame (79% finished, 320 grams). Each frame is packaged with its own serialized aluminum drilling jig, three drill bit guides, and a set of three polymer frame locking blocks. No drill bits, end mills, or slide parts are included.

Is this 80% frame bundle worth it at $529.99?
At $176.66 per frame-and-jig set, this bundle is worth it for a dedicated hobbyist who has the tooling and intends to build all three pistol sizes. Compared to purchasing these kits individually at their former retail price of approximately $150 each, this represents a $20 discount per kit. The value is contingent on your ability to complete the machining process and source the remaining slide and small parts, which typically adds another $400-600 per complete pistol.

Pros & cons
What works
- Three distinct platforms (G19, G17, G43 clones) in one SKU — provides build diversity
- Includes three dedicated aluminum jigs — eliminates guesswork for pin hole alignment
- Bundle price of $529.99 equals $176.66 per frame/jig set — a 12% discount versus historic individual pricing
Trade-offs
- Requires precise front rail module installation with a 0.005" tolerance — misalignment causes immediate slide binding
- No stippling or texturing pre-applied — adds a $50-100 finishing step or requires aftermarket grip tape
- Final production run — no future warranty support or replacement parts available from the original manufacturer

Frequently asked questions
- Are these frames compatible with Gen 3 Glock slides?
- Yes, all three frames are designed specifically for Gen 3 Glock-style aftermarket slides. The PF940Cv1 accepts G19 slides, the PF940v2 accepts G17 slides, and the PF9SS accepts G43 slides. We recommend verifying slide rail compatibility, as some OEM slides may require minor fitting. See our guide <The Complete Guide to Adjusting Slide Stop Tension> (/blog/adjusting-slide-stop-tension-in-spectre-kits/) for related setup notes.
- Does this work with Polymer80's proprietary locking blocks?
- Yes, each frame includes the correct proprietary rear rail module and polymer locking block required for that specific model. The PF940Cv1 and PF940v2 use a dual-pin locking block, while the PF9SS uses a single-pin design. These are not interchangeable with standard Glock OEM locking blocks or those from other 80% frame manufacturers like Lone Wolf.
- How long does the milling and drilling process take?
- With a proper drill press and a 3/8" end mill, a competent builder can complete the critical fire control pocket milling for one frame in approximately 20-25 minutes of active machining time. Drilling the three pin holes takes an additional 5-7 minutes per frame. Allow 2-3 hours total per frame for setup, machining, de-burring, and test-fitting components.
- Can I return it if I mess up the machining?
- No. All 80% frame sales are final. The machining process is irreversible, and any error made by the end-user voids any warranty or return eligibility. This is standard practice across the industry for unfinished receivers and frames. We strongly recommend practicing on a block of UHMW polyethylene or consulting detailed video tutorials before working on the actual frame.
