P80 Pfs9 Complete Pistol Ocs Gry - polymer 80
Pros & cons
What works
- Weighs 14.7 oz — 4.3 oz lighter than a completed OEM Glock 19 Gen 3 frame assembly.
- OCS texturing provides a consistent 120-grit equivalent grip surface without requiring post-purchase stippling.
- Enhanced 1913 rail offers 1.5 inches of usable Picatinny space for light/laser mounting.
- Includes a complete 37-component internal parts kit, saving ~$120 versus sourcing individually.
Trade-offs
- No slide, barrel, or recoil spring included — adds minimum $300+ to complete the pistol.
- The proprietary rail geometry may not fit all Glock 19-specific holsters without modification.
- The 80% lower platform requires careful pin installation; incorrect assembly can damage the polymer ears around the trigger housing pin.
- Final inventory phase — no future production runs or direct warranty support from the original manufacturer are expected.

About this product
What is the ModFuze P80 PFS9 Complete Pistol OCS Gry? This is a serialized, ready-to-assemble, modular frame kit for a Glock 19-sized pistol, built on a Polymer 80 framework with our proprietary OCS (Optimized Control Surface) texturing and enhanced 1913 accessory rail. This represents the final inventory phase for this configuration as production shifts. We advise consulting specific state and federal regulations regarding frame procurement and registration before purchase.
What is the P80 PFS9 Complete Pistol OCS Gry used for?
This kit is used to build a complete, functional 9mm pistol with a Glock 19 form factor, requiring only the installation of the provided internal component pack into the machined frame and the addition of a compatible slide assembly. The primary end-use is for individuals seeking a modular handgun platform for customization or concealed carry, with the OCS texturing providing a 40% better grip purchase than a standard P80 PF940C according to our abrasion testing. It is not supplied with a slide, barrel, or recoil spring assembly.
How does the P80 PFS9 Complete Pistol OCS Gry compare to a standard Polymer80 PF940C?
The ModFuze iteration is superior in terms of out-of-the-box frame finishing and accessory mounting versatility. Where the stock PF940C frame requires significant stippling work to achieve a high-traction grip, the PFS9 OCS Gry ships with our laser-etched pattern that achieves a consistent 120-grit equivalent surface. Its enhanced 1913 rail section provides 1.5 inches of usable Picatinny space versus the standard 0.8 inches, better accommodating weapon lights like the TLR-7A. For builders prioritizing speed and modularity, the ModFuze kit is more advanced; for those wanting a completely blank canvas for custom stippling, the standard PF940C, like our Polymer80 80% Lower Receiver and Jig Kit (LR-308), may be the better starting point.
What does it weigh and what are the dimensions?
The complete frame assembly with all internal components installed weighs 14.7 ounces (417 grams). Its critical dimensions are a grip height of 5.04 inches, a frame width of 1.18 inches at the slide rails, and an overall length of 7.36 inches. The trigger guard internal dimensions measure 0.87 inches high by 1.25 inches wide, accommodating most gloved hands. These specs result in a 4.3-ounce weight saving compared to a completed Glock 19 Gen 3 OEM frame assembly.
Who is this NOT for?
This product is not for first-time builders unfamiliar with handgun assembly tolerances or individuals in jurisdictions with restrictive laws on unserialized or self-assembled firearms. The build process, while simpler than milling an 80% lower, still requires specific tools like a 3mm punch and mallet, and the mechanical aptitude to install a trigger housing pin, a task that takes an experienced builder roughly 90 seconds but a novice upwards of 15 minutes. It is also not suitable for those unwilling to source a separate compatible slide assembly. For builders seeking a more traditional rifle platform, our .308 80% Lower – Billet may be a better fit.
What's in the box?
The box contains one (1) fully machined and serialized polymer frame in gray, one (1) complete internal parts kit (trigger mechanism, locking block, pins, and springs), one (1) set of factory-installed steel front and rear rail modules, and one (1) set of frame pins. The parts kit alone contains 37 individual components, including the cruciform-style trigger bar and reinforced polymer trigger shoe. No slide, barrel, sights, magazine, or assembly guide is included.
Is the P80 PFS9 Complete Pistol OCS Gry worth it at $489.99?
At $489.99, this kit's value is contingent on the builder's intent and regional component costs. The price point is justified by the inclusion of a high-quality internal parts kit (valued at ~$120 separately) and the proprietary OCS texturing, which eliminates a $60-$80 stippling service. However, when a compatible slide assembly (~$300+) is added, the total build cost approaches or exceeds many complete, factory-produced pistols. Therefore, its worth is highest for those who specifically want the Polymer 80 modular platform with a refined, ready-to-use frame texture and are prepared for the total system cost.

Frequently asked questions
- Is it compatible with Glock 19 Gen 3 slides?
- Yes, the PFS9 frame is designed to be fully compatible with aftermarket and OEM Glock 19 Generation 3 slide assemblies. We have verified fitment with slides from Zaffiri Precision, Brownells, and Lone Wolf. Ensure your chosen slide uses a standard dual-captured recoil spring assembly with a Gen 3 geometry.
- Does it fit standard Glock 19 holsters?
- Holster compatibility is not guaranteed. While the frame's external dimensions are based on a Glock 19, the enhanced 1913 accessory rail is 0.08 inches taller and 0.15 inches longer than the standard Glock rail. It will likely fit open-ended or adjustable light-bearing holsters (e.g., for a TLR-7A), but may not lock into molded Kydex holsters designed specifically for the OEM Glock 19 rail. Test fitment is advised.
- How long does shipping take?
- Processed orders for in-stock items typically ship within 2-3 business days via UPS Ground. Transit times are 3-7 business days within the continental United States, depending on destination. All shipments require an adult signature upon delivery and are routed through an FFL holder of your choice, which may add additional processing time.
- Can I return it if it doesn't fit my slide?
- No. Due to the regulated nature of the serialized frame, all sales are final once the frame has been transferred through an FFL. We strongly recommend verifying compatibility with your specific slide components before initiating the transfer. We provide detailed rail dimension diagrams (17.5mm center-to-center on front rails) on our product support page for pre-purchase verification.
