P80 Compact Slide Assembly -PF940C/PFC9 – Cobalt - polymer 80
About this product
The Polymer80 P80 Compact Slide Assembly PF940C/PFC9 Cobalt is a complete 9mm slide assembly designed for PF940C/PFC9 frames with Cerakote finish, suppressor-height sights, and a threaded barrel. It ships fully assembled with all necessary internal components and recoil spring. This slide is engineered for direct compatibility with Polymer80 compact frames and Gen 3 Glock 19 platforms without modification.
What is the P80 Compact Slide Assembly used for?
This slide assembly is designed for building or upgrading Polymer80 PF940C/PFC9 compact frames and Gen 3 Glock 19 pistols. It provides a complete slide solution with suppressor-height night sights and threaded barrel capability. The assembly requires no gunsmithing for installation beyond basic frame completion.
How does the P80 Compact Slide Assembly compare to OEM Glock slides?
The Polymer80 slide weighs 14.8 oz compared to OEM Glock's 15.2 oz, making it slightly lighter while maintaining durability. Where Polymer80 excels is in aftermarket features—it includes suppressor-height Night Fision sights and a threaded barrel that would cost $180+ to add to an OEM slide. However, OEM Glock slides still have better track record for absolute reliability in adverse conditions.
What does it weigh and what are the dimensions?
The complete slide assembly weighs 14.8 oz (420g) with all components installed. Slide dimensions are 6.8 inches long, 1.2 inches wide, and 1.4 inches tall. The barrel length measures 4.02 inches including threads, with a 1/2x28 thread pattern extending 0.6 inches beyond the slide.
Who is this NOT for?
This slide is not suitable for California residents needing serialized components or builders seeking non-threaded barrels for compliance. The cobalt Cerakote finish shows holster wear faster than nitride finishes, making it a poor choice for daily carry where cosmetic preservation is priority. For those needing basic range slides, consider our Polymer80 LR-308 80% Lower Receiver for simpler builds.
What's in the box?
The box contains one complete slide assembly with installed internals, one threaded 9mm barrel, suppressor-height Night Fision night sights pre-installed, and one recoil spring assembly. No tools or additional parts are included—the assembly ships ready for immediate installation on compatible frames.
Is the P80 Compact Slide Assembly worth it at $450?
At $450, this slide assembly delivers good value for builders wanting threaded barrel and night sights without separate purchases. The combined cost of comparable aftermarket slide, threaded barrel, and suppressor-height sights typically exceeds $500. For builders who don't need threaded capabilities, our guide to polymer slide maintenance covers alternative options.

Frequently asked questions
- Is it compatible with Gen 3 Glock 19 frames?
- Yes, it's fully compatible with Gen 3 Glock 19 frames without modification. The slide uses standard Gen 3 recoil spring and locking block specifications. Installation takes approximately 2 minutes with proper frame preparation.
- Does it fit standard Glock 19 holsters?
- It fits most Gen 3 Glock 19 holsters, but the suppressor-height sights may require holsters with sight channels. The threaded barrel adds 0.6 inches to overall length, which may interfere with some closed-front holsters. Check with your holster manufacturer for specific compatibility.
- How long does shipping take?
- Standard shipping takes 3-5 business days within continental US. Expedited options are available through UPS for 2-day delivery. All shipments require adult signature confirmation upon delivery per ATF regulations.
- Can I return it if it doesn't fit my frame?
- Returns are accepted within 30 days for uninstalled, unfired products. The product must be in original packaging with all components. Custom-built firearms components are generally non-returnable once installed or fired, as stated in our warranty policy.
- Does this work with Holosun 507C optics?
- No, this slide is not optics-ready and requires milling for red dot installation. The slide is designed for iron sights only. Milling services typically cost $150-$200 and take 2-3 weeks through certified gunsmiths.
- Is the barrel threaded for suppressors?
- Yes, the barrel features 1/2x28 threads compatible with most 9mm suppressors. The thread length is 0.6 inches with standard pitch. Always use appropriate thread locker and check alignment with alignment rods before use.
