About this product
The Polymer80 PF-Series Complete 9mm Slide Assembly is a factory-assembled slide and barrel combination for PF940C/PFC9 frames, featuring Cerakote finish, suppressor-height night sights, and threaded barrel. This ready-to-install assembly eliminates parts sourcing and fitting time for builders seeking immediate functionality. It ships complete with all internal components pre-installed and properly torqued.
What is the P80 Compact Slide Assembly used for?
This assembly enables rapid completion of Polymer80 PF940C/PFC9 or OEM Gen 3 Glock 19 builds without separate parts acquisition. The compensators, while suppressor-height Night Fision sights provide immediate suppressor sight picture alignment. Installation requires only slide installation onto frame rails and function testing.
How does the P80 Compact Slide Assembly compare to Brownells Slide?
The Polymer80 assembly includes fully installed internals and suppressor-height night sights, whereas Brownells slides ship as bare components requiring separate parts kits and sight installation. Brownells slides offer more custom finish options but require additional $120-180 in parts and 45-60 minutes gunsmithing time to reach equivalent functionality.
What does it weigh and what are the dimensions?
The complete assembly weighs 14.2 oz (402 grams) with dimensions inches long, 1.18 inches wide, and 1.26 inches tall. The 4.02-inch threaded barrel adds 0.5 inches compared to standard Glock 19 barrels, maintaining proper cycling with standard 115-g standard 1.8 inches.
Who is this NOT for?
This assembly is unsuitable for builders seeking custom slide cuts or non-standard finishes, as the Cerakote cobalt finish is fixed and machining would void warranty. It's also incompatible with Gen 4/5 Gl for approximately $75-100 savings despite increased assembly time.
What's in the box?
The package contains one complete slide assembly with installed internals, one threaded barrel, suppressor-height Night Fision night sights pre-installed, and one recoil spring assembly. No additional tools or components are included—installation requires only existing frame and minimal lubrication. All components arrive packaged in anti-corrosion paper with factory torque specifications verified.
Is the P80 Compact Slide Assembly worth it at $450?
At $450, this assembly justifies its premium for builders valuing time savings and guaranteed compatibility over component sourcing. Compared to the Polymer80 LR-308 80% Lower Receiver, this represents a complete upper solution rather than a raw component. Builders should reference lubrication data for optimal performance.

Frequently asked questions
- Is it compatible with Gen 4 Glock frames?
- No, this assembly only fits Gen 3 Glock frames and Polymer80 PF940C/PFC9 frames. Gen 4 and Gen 5 frames require different recoil spring assemblies and rail dimensions that this slide doesn't accommodate.
- Does it work with Holosun 507C?
- No, this slide isn't optic-cut—it requires additional milling by a gunsmith costing $150-250. Direct mounting isn't possible without modification to the slide's top surface.
- How long does shipping take?
- Returns are accepted within 30 days if product is unused and original packaging intact, but require a 15% restocking fee. Fitting issues typically indicate frame out-of-spec rather than slide malfunction.
