Polymer80 PF940v2 80% Full Size Frame Kit — The Gold Standard for Custom Glock Builds

There’s a reason the Polymer80 PF940v2 consistently outsells every other 80% pistol frame on the market. Its compatibility with Glock 17, 22, 24, 31, 34, and 35 Gen 3 components — spanning 9mm, .40 S&W, and .357 SIG — combined with Polymer80’s ergonomic frame improvements makes it the logical starting point for any serious pistol builder.

California Gun Shop maintains a robust selection of 80% frame products. The PF940v2 sits within our 80% Frames category alongside the PF940CL long-slide compact and PF45 large frame kit. For slide assemblies that pair with this frame, see our Complete G17 Slide for P80 PF940v2 — a ready-to-install upper assembly.

The PF940v2 Advantage Over Factory Glock

Factory Glock frames are functional and proven. But the PF940v2 offers several improvements that Glock hasn’t adopted in their standard production models:

• Grip angle: The PF940v2 uses a 17-degree grip angle vs. Glock’s 22 degrees. Many shooters find the less steep angle more natural, producing a more instinctive point-of-aim without requiring a wrist adjustment
• Undercut trigger guard: Allows a proper high grip without the trigger guard digging into the middle finger. Reduces felt recoil and speeds up follow-up shots
• Enhanced texture: More tactile grip texture without the abrasiveness of aggressive stippling jobs. Works in all weather and with gloves
• Flared magwell: Integrated magwell flare that guides magazines into the well faster for competition-speed reloads
• Picatinny rail: Full-length integrated accessory rail for weapon lights, lasers, and combination units

⚠️ California Residents — Critical Legal Information

California law imposes specific and significant requirements on the manufacturing of unserialized firearms within the state. Before purchasing and especially before completing any 80% frame, California residents must understand the following:

• Serial Number Required: California Penal Code 29180 requires any person who manufactures or assembles a firearm to first obtain a unique serial number from the California DOJ via the CFARS (California Firearms Application Reporting System) online portal
• Before Machining: The serial number must be obtained and engraved on the frame BEFORE any manufacturing operations begin
• Handgun Roster: Completed homemade pistols in California must meet applicable DOJ safety device requirements and cannot be transferred to another person
• Local Restrictions: Some California cities and counties have additional restrictions beyond state law

Purchasing an unfinished 80% frame may be permissible under certain interpretations of California law. However, the legal landscape for 80% frames in California is complex and actively evolving. California Gun Shop strongly recommends that all California residents consult with a California-licensed firearms attorney before purchasing this product. We provide this information for educational purposes only and do not provide legal advice.

Frequently Asked Questions

Q: Is there a trigger included with the PF940v2 kit?

A: No. The PF940v2 kit includes only the frame blank and machining jig. The trigger, trigger bar, and all lower parts must be sourced separately through a Glock Gen 3 full-size Lower Parts Kit (LPK). Many builders take this opportunity to upgrade to aftermarket triggers from Ghost, ZEV, or Apex for improved trigger pull characteristics.

Q: Can I install a Glock OSD (Operator Slide Disassembly) or Gen 5 magazine catch?

A: The PF940v2 is Gen 3 compatible, meaning it uses the standard Gen 3 magazine release design. Gen 4 and Gen 5 reversible magazine catches are not compatible without modification. Some aftermarket manufacturers offer extended or ambidextrous magazine releases designed specifically for Gen 3 frames that work well with the PF940v2.

Q: What’s the maximum safe round count before the frame may need inspection?

A: Properly built PF940v2 frames with quality aftermarket components regularly last tens of thousands of rounds. The weakest points in a build are typically the locking block and rear rail module, which are why stainless steel upgrade components from ROOK Tactical and similar manufacturers are popular. Polymer80 recommends inspecting the locking block and rail module every 5,000 rounds for wear.

Q: What is the best color choice for a duty or defensive build?

A: Black is the most common choice for duty and defensive builds — it’s the most neutral color, shows the least visible wear over time, and is appropriate in virtually any holster. FDE (Flat Dark Earth) is popular with shooters who use tan/coyote gear. OD Green is a classic tactical option. For competition builds, color is a personal choice — many competitors enjoy distinctive colors for quick visual identification of their pistol at the range.

Q: Can I build the PF940v2 as a compensated pistol with a threaded barrel?

A: Yes. Select a threaded G17 or G34 barrel in your caliber and pair it with a compatible compensator. California Gun Shop carries compatible slides with threaded barrel clearance notches. Note that in California, short-barreled configurations and certain muzzle devices may be restricted — consult California law and a firearms attorney before adding a compensator to ensure compliance.
