What Makes It Stand Out
This isn’t just a parts bundle; it’s a complete platform starter kit. You’re getting three distinct 80% frame platforms—the PF940Cv1 (Compact), the PF940v2 (Full-size), and the PF9SS (Subcompact)—all in one box. In our warehouse, the fit and finish on these black frames is exactly what you’d expect from Polymer80: consistent, well-machined, and the polymer construction feels durable in hand. The included jigs are the real workhorses, providing the precise guidance needed for a clean, professional-grade milling job. We’ve found that bundling these three popular models gives builders incredible flexibility to experiment with different sizes and calibers without placing multiple separate orders.

What We Like & Don’t
✅ Pros:
- Exceptional Value for Multiple Builds: Getting three complete frame/jig kits for this price is a significant saving over buying individually. Our sales data shows this is why it’s a top reorder item.
- Proven, Reliable Jig Design: The Polymer80 jig system is tried and true. The steel drill bushings in the polymer jig body prevent bit walk and ensure clean, accurate holes—a critical factor for a successful build.
- Build Flexibility: This bundle lets you tackle a full-size range project, a compact carry piece, and a subcompact, all with the same quality base components. It’s a workshop in a box.
- Consistent Quality: Having handled this product directly, we can confirm the machining on the fire control pocket and rails is clean, and the polymer has a solid, quality feel without flash or imperfections.
- Complete Kit: Comes with all the specific drill bits and the end mill bit you need. No last-minute runs to the hardware store.
❌ Cons:
- Single Color Option: The bundle is only available in black. If you want FDE, gray, or OD green, you’ll need to source frames separately.
- Storage Consideration: You now have three projects in progress. You’ll need a good organization system for the parts, jigs, and tools for each frame to avoid mixing components.
- Upfront Cost: The total price is higher than a single kit, which might be a barrier for someone just wanting to try a single, first-time build.
Is This Right for You?
Buy this bundle if: You’re an experienced builder looking to stock up on multiple platforms efficiently, a first-timer who wants to commit to learning and have spare frames for practice (or mistakes), or someone who wants the flexibility to build for different roles (home defense, competition, concealed carry) without waiting for multiple shipments.
Skip this bundle if: You only have a specific, single build in mind and don’t foresee building others, you’re on a very tight budget and a single frame kit meets your immediate needs, or you require a specific color other than black for all your frames.
Common Questions
What exactly is included in the box?
You get three separate, complete kits: 1) A PF940Cv1 80% frame and its dedicated jig. 2) A PF940v2 80% frame and its dedicated jig. 3) A PF9SS 80% frame and its dedicated jig. Each kit also includes the necessary frame pins. The bundle includes the drill bits and end mill bit needed to complete all three frames.
Are the jigs reusable?
Yes, the jigs are designed to be reusable for multiple frames of the same model. However, this bundle includes one jig per frame model. The durability of the jig is a key strength; in our use, they hold up well to multiple milling operations if you source additional frames later.
What tools do I need to complete these frames?
At a minimum: a hand drill or drill press, a hammer, and a set of punches. A sturdy bench vise is highly recommended to securely hold the jig. Safety glasses are non-negotiable. A Dremel tool with sanding drums can help with final cleanup, but the end mill bit does the main work.
Is this compatible with aftermarket slides and parts?
Yes. The PF940Cv1, PF940v2, and PF9SS frames are designed to be compatible with a vast array of aftermarket and OEM Glock®-pattern slides, barrels, and internal parts kits for their respective models (G19, G17, G43). Always confirm compatibility with your specific parts supplier.
Where can I buy the PF940Cv1™, PF940v2™, and PF9SS™ 80% Frame and Jig Kit Bundle online?
You can purchase this specific bundle right here at Polymer80Builds. We’re a USA-based seller that has stocked and shipped this kit since spring 2025, and we handle every order that comes through our Medford, Oregon warehouse.
How difficult is the milling process for a beginner?
It’s a very manageable project with patience and the right tools. The jig does most of the guiding work. The most common issue for beginners is rushing. Go slow, let the drill and end mill do the work, and clear polymer debris frequently. Our customer feedback of 4.4/5 suggests most builders are successful and satisfied with the process and outcome.
Do you offer any build guides or support?
Absolutely. As builders ourselves, we provide detailed, step-by-step build guides and video resources focused on the practical, hands-on aspects of completing a Polymer80 frame. Check our website’s guides section or contact our support team for specific questions.
