Polymer80 PF940V2 Bare Frame – Glock 17/22 Gen 3 Compatible

Overview

The Polymer80 PF940V2 is the original 80% full-size frame that redefined the home-build market. This isn’t a parts kit or an assembly—it’s a Polymer80 PF940V2 frame in its bare, unfinished state, designed for the builder who already has the tools and the know-how. We’re talking about experienced enthusiasts who have a jig, a drill press or router, and the completion parts ready to go. This offering strips out the redundant tools to deliver the core component at a value price. It’s for the person who wants the satisfaction and customization of a true build, not just a simple assembly, resulting in a reliable, Gen3-compatible platform for full-size 9mm, .40 S&W, and .357 Sig builds.

Key Features

• High-Strength Reinforced Polymer: Engineered to withstand rigorous use, offering a durable yet lightweight foundation that rivals OEM specifications for longevity and performance.
• Aggressive Grip Texture & Extended Beavertail: Provides superior control and a high, consistent hand position to manage recoil instinctively, reducing muzzle flip for faster follow-up shots.
• Pre-Installed Stainless Steel LBRS & Drop-in RRM: The Locking Block Rail System and Rear Rail Module come installed and hardened, eliminating the most critical alignment headaches and ensuring proper barrel lockup right out of the gate.
• Full Picatinny/STANAG Accessory Rail: Securely mounts lights, lasers, and other mission-critical tools without the wiggle or fitment issues found on some aftermarket frames.
• Blank Serialization Plate: Offers a clean, flat area for personalization or compliance marking according to local laws, giving you control over the final presentation.
• Hardened Pins Included: Comes with the necessary hardened pins for a complete frame assembly, so you’re only sourcing the slide and lower parts kit.

Why Choose This Frame

In a market flooded with clones and questionable quality, the PF940V2 stands as the benchmark. Polymer80 didn’t just make a copy; they engineered a solution to common gripes with the OEM platform. The ergonomics are intentionally enhanced—that aggressive texture and extended beavertail aren’t just for looks. They solve real problems like grip slip during rapid fire and slide bite. The pre-installed, stainless steel rail system is the key differentiator; it’s what turns a block of polymer into a precision firearm foundation. While others might include cheap jigs and brittle drill bits to appeal to beginners, this bare frame package respects your existing workshop and your intelligence. You’re paying for the engineered component, not the disposable tools.

Compatibility

This is critical: The PF940V2 is designed specifically for 3-pin, Generation 3 Glock-style parts. It is not compatible with Gen4, Gen5, or earlier generations. It accepts standard full-size components.

• Slide Compatibility (9mm): Glock 17, 17L, 34 slides
• Slide Compatibility (.40 S&W / .357 Sig): Glock 22, 35, 24, 31 slides
• Magazine Compatibility: Uses standard Glock 17 (9mm) or Glock 22 (.40/.357) magazines, depending on your caliber choice.
• Lower Parts Kit: Requires a standard Gen3 Glock-compatible lower parts kit (LPK).

Note: Building in .40 S&W or .357 Sig requires the correct caliber-specific slide, barrel, and ejector.

Real-World Use Cases

This frame isn’t a theoretical project; it’s a solution. Here’s how builders actually use it:

• The Custom Competition Gun: A shooter starts with this blank-slate PF940V2 to build a dedicated USPSA or IDPA Limited/Production optic-ready pistol, machining it to accept only the specific aftermarket trigger components they trust, and stippling the frame to their exact grip preference without worrying about voiding an OEM warranty.
• The Cost-Effective Duty-Style Backup: An experienced owner with spare tools and a spare LPK sources a police trade-in Glock 22 slide and barrel. They pair it with this frame to create a reliable, full-size .40 caliber firearm for a fraction of the cost of a new OEM gun, with better ergonomics to boot.
• The Precision .357 Sig Build: Using a aftermarket Glock 31-length slide and a KKM precision barrel, a builder creates a uniquely chambered pistol for a specific purpose, leveraging the PF940V2’s robust platform to handle the snappy .357 Sig cartridge with a fully customized trigger feel.
• The Advanced First Build: A mechanically-inclined individual who already owns a router and vise from other hobbies skips the “starter kit” and chooses this bare frame. They follow detailed online guides, sourcing their own quality drill bits and jig, often resulting in a more precise finish and a deeper understanding of the platform’s mechanics.

Legal / Compliance Notice

This product is an unfinished firearm component, often referred to as an “80% frame” or “receiver blank.” It is not a firearm and is not regulated as such under federal law at the time of sale.

Frequently Asked Questions

Q: What exact tools do I need to complete this PF940V2 frame?
A: At a minimum, you’ll need a reliable drill press or a router with a good vise, a set of quality carbide drill bits (3mm & 4mm are critical), and the appropriate end mill for clearing the fire control group pocket. A hand drill is not recommended for precision. You will also need a lower parts kit, slide, barrel, and magazine to complete the firearm.

Q: Is the rear rail module really “drop-in”? I’ve heard about fitment issues.
A: The term “drop-in” refers to the Polymer80 design not requiring welding or bending of rails like some early 80% designs. The stainless steel RRM is pre-installed in our frames. However, achieving a perfect slide fit sometimes requires minor, careful filing of the rail channels—this is normal in precision building. It’s why having a set of fine files and calipers is part of an experienced builder’s kit.

Q: Can I use a Glock 19 slide on this full-size PF940V2 frame?
A: No. The PF940V2 is a full-size frame. A Glock 19 (compact) slide will not fit properly; there will be a significant gap at the front of the dust cover. You need a full-size slide (G17/22 length or longer).

Q: Once I finish it, do I have to serialize or register it?
A: Federal law does not require a personally made firearm (for personal use) to be serialized. However, several states now have laws requiring the application of a serial number. You must research and comply with the laws of your specific state and locality. The blank serialization plate on the frame is provided for this potential purpose.
