Overview
The Polymer80 PF940V2 is the refined, full-size 80% frame kit that set the modern standard for the home builder. This isn’t just a block of polymer; it’s the successor to the original PF940v1, incorporating every ergonomic and functional upgrade learned from its compact siblings. If you’re a hobbyist looking to build a full-size Glock-pattern pistol on a rock-solid, no-FFL-required foundation, this is the platform. The PF940V2 kit gives you the ultimate in personalization—you’re not just buying a gun, you’re building one to your exact grip, trigger, and sight preferences. It’s for the shooter who values the process as much as the product.
Key Features
- Redesigned Ergonomic Grip: Aggressive texturing on the front strap, rear strap, and side panels ensures a locked-in grip that won’t shift during rapid fire, even with sweaty hands.
- Enhanced Beavertail: The extended beavertail allows a higher, more natural hand position, dramatically reducing slide bite and improving recoil control for faster follow-up shots.
- Integrated Locking Block Rail System (LBRS): Our stainless steel LBRS is a single, hardened unit. Unlike some flimsy multi-piece rails, this design guarantees perfect barrel lockup and long-term frame durability.
- Drop-In Rear Rail Module (RRM): Simplifies the build process immensely. This precision-machined component ensures your slide-to-frame fit is correct from the start, a critical factor for reliability.
- STANAG-Compliant Accessory Rail: Not just “Picatinny-style.” This rail meets mil-spec dimensions, so your lights, lasers, and comps will mount securely without wobble or fitment issues.
- Complete Jig & Tooling: The included finishing jig is CNC-machined for accuracy, and comes with the correct drill bits. This isn’t a throwaway piece of plastic; it’s a precision guide for a professional result.
Why Choose This Kit
In a market flooded with imitators, the original Polymer80 PF940V2 stands apart. The polymer blend isn’t just “tough plastic”; it’s a glass-reinforced nylon compound engineered for impact resistance and fatigue strength where it counts—around the rail systems and pin holes. We’ve seen frames with thousands of rounds that show minimal wear. The included rail components are 4140 steel, heat-treated, not soft mystery metal that deforms under pressure. While other kits might get you 90% there, the PF940V2’s design maturity means you avoid the common headaches of out-of-spec rails or poorly located pin holes that can turn a fun project into a frustrating paperweight. You’re paying for proven engineering, not just a project.

Compatibility
This is critical: The PF940V2 frame is designed specifically for Generation 3 Glock large-frame slides and parts. It is compatible with OEM or aftermarket slides/parts kits for the following models:
- 9mm: Glock 17, Glock 17L, Glock 34
- .40 S&W / .357 SIG: Glock 22, Glock 24, Glock 31, Glock 35
Note: It uses the 3-pin Gen3 design. It is NOT compatible with Gen4 or Gen5 slides, which have different recoil spring assemblies, locking blocks, and pin configurations. For .40/.357 builds, you must use the corresponding caliber-specific slide, barrel, and ejector.
Real-World Use Cases
This kit isn’t a one-trick pony. Here’s how builders are actually using the PF940V2:
- The Duty-Ready Backup: Building a reliable, full-size pistol with night sights and a weapon light for home defense, using all OEM Glock internal parts for proven reliability.
- The Competition Foundation: Creating a dedicated USPSA or IDPA Limited division gun. The frame accepts aftermarket triggers, extended mag releases, and stippling perfectly, letting you build a race gun without modifying an existing serialized frame.
- The “Unobtainium” Build: Sourcing a aftermarket slide in a rare caliber or configuration (like a Glock 17L longslide or a ported 34) and needing a quality frame to complete the build without dealing with an FFL transfer.
- The Teaching Tool: Using the build process itself as a hands-on lesson in firearm mechanics and gunsmithing fundamentals, resulting in a functional tool you know inside and out.
Legal / Compliance Notice
PLEASE READ CAREFULLY: This product is a legal firearm component. It is the purchaser’s sole responsibility to understand and comply with all applicable federal, state, and local laws regarding the purchase, possession, completion, and use of this item. You must be 21 years of age or older to purchase. It is illegal for prohibited persons to possess any firearm or firearm component. The completion of an 80% frame into a functional firearm is legal for personal use under federal law, but some states and municipalities have restrictions or outright bans. It is YOUR responsibility to know your local laws. Once completed, a firearm made for personal use does not require a serial number under federal law, but some states now mandate serialization. We recommend you permanently mark your firearm with a unique identifier. This product is sold “as-is” for educational or manufacturing purposes.

Frequently Asked Questions
Q: What tools do I absolutely need to finish this frame?
A: At a minimum, you need a reliable drill press or a sturdy handheld drill and a good vise. A drill press with an XY cross-vise is highly recommended for perfect pin hole alignment. You’ll also need a set of files or a Dremel tool with router base to clear the recoil spring channel. Basic hand tools (hammer, punches, screwdrivers) are needed for assembly.
Q: Can I use a Gen4 or Gen5 slide on this PF940V2 frame?
A: No. The PF940V2 is designed for Gen3 parts only. Gen4 and Gen5 slides have a different recoil spring assembly diameter and a different locking block/lug geometry. They will not function. You must source a Gen3-compatible slide and parts kit.
Q: How difficult is the build for a first-timer?
A: With patience and attention to detail, it’s very achievable. The included jig is excellent. The most common mistakes are rushing the drilling (causing misaligned holes) or over-milling the recoil spring channel. Go slow, follow quality video tutorials, and test-fit your slide frequently during the milling process. It’s a rewarding project.
Q: Is the blank serialization plate required?
A> Under current federal law, no. A firearm built for personal use is not required to have a serial number. However, several states (like California, New York, and others) have enacted laws requiring self-manufactured firearms to be serialized with a state-issued number. The blank plate is provided for your convenience if you choose or are required to mark your frame. It is your responsibility to comply with all laws in your jurisdiction.
