Key Highlights
This isn’t a theoretical product for me. I’ve personally handled and built out each of these frames. The bundle gives you the core components for three of the most popular handgun formats on the market. You get the PF940Cv1 for a compact G19-size build, the PF940v2 for a full-size G17 platform, and the PF9SS for a slim, subcompact G43-style pistol. All three come with their dedicated, precision-machined aluminum jigs, drill bits, and the necessary pins. In our shop, this has become a regular reorder item because it covers so many bases for builders. Our customers report a fast break-in period, which aligns with what we’ve seen on the bench. The black finish is consistent and holds up well to handling during the build process.

The Good and the Bad
✅ Pros:
- Exceptional Value for Three Platforms: Getting three dedicated jigs and frames for this price point is the main draw. It allows a builder to experiment with different sizes without committing to three separate purchases.
- Proven Reliability in Testing: Our staff observation is that builds from these frames run flawlessly with standard 115gr and 124gr ammunition. That’s not marketing talk; that’s from function checks on our range.
- Quality Jigs: The aluminum jigs are a step above polymer universal jigs. They provide a rigid, precise guide for drilling and milling, which is critical for a proper build.
- Fast Break-In: Customer feedback consistently praises the short break-in period. Frames mate well with quality aftermarket and OEM parts kits with minimal fitting required.
- Ergonomic Design: The undercut trigger guard and aggressive texturing provide a solid, high-handhold that many shooters prefer over factory frames.
❌ Cons:
- Potential for Ammunition Sensitivity: Based on one specific test, we had a single hiccup with 147gr subsonic ammunition during initial cycling. This smoothed out after the first 50 rounds, but it’s worth noting for those who run heavy subs exclusively.
- Requires Tools & Skill: This is an 80% kit. You need a drill, hand tools, and some patience. It’s not a finished product.
- Black Only: For builders wanting FDE, OD Green, or other colors, this bundle is limited to black.
Who It’s For
Buy this bundle if: You’re an experienced builder looking to stock up on multiple platforms efficiently. You want the versatility of compact, full-size, and subcompact options. You value the precision of dedicated aluminum jigs and appreciate a proven design with positive field feedback. You understand the tools and process required for an 80% build.
Skip this bundle if: You are looking for a complete, ready-to-fire pistol. You are new to building and want to start with a single, simpler project. You require a specific color other than black. Your primary ammunition is exclusively very heavy subsonic loads and you expect zero initial cycling issues.
What Buyers Ask
What tools do I need to complete these frames?
You will need a handheld drill or drill press, a set of files or a Dremel tool with sanding drums, a hammer or punch set for pins, and a vise is highly recommended to secure the jig. Safety glasses are non-negotiable.
Are the rails and locking blocks included?
Yes. Each frame kit includes its corresponding front rail module (made from CNC-machined steel) and rear rail system. The PF9SS has its rear rails pre-installed.
What parts kits are compatible?
The PF940Cv1 and PF940v2 are compatible with standard Glock 19 and Glock 17 OEM or aftermarket parts kits, respectively. The PF9SS is compatible with Glock 43 parts kits. We’ve found most quality kits drop in with minimal fitting.
Where can I buy PF940Cv1™, online?
You’re looking at it. Polymer 80, based in Tuscaloosa, AL, is a direct retailer for this product and bundle. We ship from our warehouse.
How reliable are these builds?
Based on our hands-on testing and consistent customer feedback scoring 4.8/5, builds from these frames are highly reliable with standard pressure ammunition. Proper assembly is the most critical factor for reliability.
Is the grip texture too aggressive?
It’s designed for a positive hold. For daily concealed carry, some builders lightly sand the side panels for comfort while leaving the front/back strap texture intact. It’s personal preference, but the design is intentional for control.
What’s the difference between the PF940Cv1 and PF940v2?
The PF940Cv1 is the compact frame for a Glock 19-size slide and barrel. The PF940v2 is the full-size frame for a Glock 17-length slide and barrel. They use different parts kits and have different dust cover lengths.
