Is it compatible with a Polymer80 PF940C (Compact) frame?

No. This Full Size Slide Assembly is specifically designed for the Polymer80 PF940v2 (full-size) and PFS9 frames. The PF940C compact frame uses a shorter slide length of 6.85 inches. Attempting to install this 7.32-inch slide on a compact frame will cause functional and safety failures.

Does it fit a Gen 4 Glock 17 frame?

No, it does not. This assembly is only compatible with Gen 3 Glock pattern frames, which include the Polymer80 PF940v2/PFS9 and OEM Gen 3 Glock 17/22 frames. The recoil spring assembly and slide internals are not compatible with the dual-spring recoil system of Gen 4 and Gen 5 frames.

How long does shipping take?

Orders ship within 1 business day via USPS Priority Mail or FedEx Ground. Shipping times are typically 2-5 business days within the continental United States. International shipping and expedited options are available at checkout, with final delivery estimates provided by the carrier.

Can I return it if it doesn't fit my frame?

Returns are accepted within 30 days for uninstalled, undamaged products. Due to firearms regulations, installed or modified slides cannot be returned. We strongly recommend verifying your frame model (PF940v2 or PFS9) before purchase. Fitting issues with verified compatible frames are covered by our warranty and will be resolved directly.

Does this work with aftermarket Glock magazines?

Yes. This slide assembly functions with all standard Gen 3 Glock-pattern 9mm magazines, including OEM Glock, Magpul PMAG, ETS, and other reputable aftermarket brands. We tested 5 different magazine types during our 500-round function test with zero feeding issues.

Is the barrel threaded for a suppressor?

No. The included barrel is a standard, non-threaded profile. It has a crown diameter of 0.375 inches (9.5 mm) and is not cut for muzzle devices. If you require a threaded barrel, you will need to purchase one separately and swap it into this slide assembly.

Pros & cons

What works

Drop-in ready — installs in under 10 minutes with a single punch, no fitting required
Complete kit — includes sights, barrel, and all internal parts for $508.50 (saves $100+ vs. separate Cerakote)
Precision weight — 14.8 oz matches OEM slide mass within 2% for reliable cycling
Factory-assembled — all parts installed and function-tested to eliminate builder error

Trade-offs

Gen 3 only — incompatible with Gen 4/5 Glock frames or compact P80 frames
No optic cut — requires third-party milling ($150-$250) for red dot mounting
Basic sights — includes standard polymer sights, an immediate $50-$80 upgrade for serious use

Expert review

I tested this GLOCK FRT slide assembly over a 30-day period, putting 500 rounds of mixed 115gr and 124gr ammunition through it on a PF940v2 frame I built. The first detail I noticed was the smooth, even Cerakote finish; no tool marks on the internal rails, and the slide cycled with a consistent, authoritative sound—no grinding, no hesitation. Installing it took me 8 minutes with a roll pin punch, and it headspaced correctly on the first attempt, a rarity in aftermarket slides. Compared directly to a Brownells stripped slide I used on a previous build, the GLOCK FRT assembly eliminates the critical failure point of part compatibility. The Brownells slide required sourcing 8 separate components and 2 hours of fitting, and still had occasional light primer strikes. This GLOCK FRT unit had zero failures in my test. The difference is quantifiable: 100% reliability over 500 rounds vs. the 97% I typically see with pieced-together builds, saving at least $75 in potential troubleshooting labor. The honest weakness is the sight system. The included polymer sights are serviceable but have a mushy, indistinct click during adjustment. For a build at this price point, I expected metal sights. After 200 rounds, the front sight developed a slight wiggle that required re-tightening with a sight pusher. This isn't a deal-breaker, but it's the first component most shooters will replace, adding to the total cost. I recommend this assembly to any builder of a Polymer80 PF940v2 or PFS9 who wants a guaranteed functional result without becoming a part-time gunsmith. Skip this if you own a Gen 4/5 Glock or want an optics-ready platform out of the box. For a straightforward, reliable slide solution that works precisely as advertised, this is the most efficient path to a finished pistol.

About this product

The GLOCK FRT Glock-Mod P80 Full Size Slide Assembly is a complete 9mm slide and barrel combination cerakoted in OD Green for immediate installation on Polymer80 PF940v2/PFS9 frames or OEM Gen 3 Glock frames. It is our latest 2026 release, featuring factory-installed parts and sights for a true drop-in solution. This assembly eliminates the need for individual part sourcing and gunsmith fitting, providing a direct performance upgrade path.

What is the P80 Full Size Slide Assembly used for?

This assembly is used to complete a Polymer80 PF940v2 or PFS9 frame, creating a functional pistol without requiring OEM Glock parts. The slide arrives fully assembled with sights, internal parts, guide rod, and a cerakoted barrel, ready for installation. This reduces build time from hours to under 10 minutes and ensures proper part compatibility, a common failure point for first-time builders. It is the fastest path to a functional P80 build.

How does the P80 Full Size Slide Assembly compare to a factory Glock 17 slide?

The GLOCK FRT assembly offers a cost-effective and aesthetically unique alternative to a factory Glock 17 Gen 3 slide. Our assembly is better for custom builds, providing a proprietary OD Green Cerakote finish and coming fully assembled for $508.50, whereas sourcing a used OEM slide and barrel separately often costs over $550 before factoring in parts labor. However, the factory Glock slide retains superior long-term proprietary metallurgy for extreme round counts above 50,000.

What does it weigh and what are the dimensions?

The complete slide assembly weighs 14.8 ounces (420 grams) and has a slide length of 7.32 inches (186 mm). Its width measures 1.0 inch (25.4 mm) across the slide, and the overall height with sights is 1.4 inches (35.6 mm). These dimensions and weight are within 2% of an OEM Glock 17 slide, ensuring reliable cycling and holster compatibility. The specific numbers confirm it's a direct fit, not an approximation.

Who is this NOT for?

This assembly is not for owners of Gen 4 or Gen 5 Glock frames, or any frame other than the Polymer80 PF940v2/PFS9 or Gen 3 Glock. It is also not ideal for competitive shooters seeking ultra-lightweight slide cuts, as it is a solid, uncut profile. If you require a skeletonized or optic-ready slide from the factory, consider our Glock-Mod 3.5lb Connector for trigger work instead of slide modification.

What's in the box?

The box contains the complete slide assembly with installed sights, a cerakoted barrel, a recoil spring assembly (guide rod and spring), and all necessary internal slide parts (striker, extractor, plunger, etc.). All components are pre-assembled and function-tested; you receive one ready-to-mount slide. No additional small parts, tools, or instructions are included, as installation requires only a punch to remove the rear slide cover plate, a process taking under 60 seconds.

Is the P80 Full Size Slide Assembly worth it at $508.50?

At $508.50, this assembly is worth it for builders who value time savings and guaranteed compatibility over sourcing parts individually. The price includes the Cerakote finish, which adds a $100+ value vs. bare steel, and eliminates 2-3 hours of part-sourcing and fitting labor. Compared to piecing together a similar build from various aftermarket brands, this single-vendor solution from GLOCK FRT ensures reliability. Pair it with our V3 Trigger Shoe Kit for a complete performance build.
