About this product
The P80 Full Size Slide Assembly – PF940v2/PFS9 – OD Green is a complete, drop-ready slide assembly designed for installation on polymer 80% frames. It is built specifically for the PF940v2 and PFS9 platform, which accept Gen 3 Glock 19-style upper components. The assembly includes factory-installed sights, a barrel, and a recoil spring, requiring no additional gunsmithing for basic function.
What is the P80 Full Size Slide Assembly used for?
The P80 Full Size Slide Assembly is used to complete a functional pistol from a polymer 80% lower receiver or ReadyMod frame. This assembly converts the PF940v2 or PFS9 frame from a non-firing platform to a complete firearm after serialization and compliance steps are completed. It eliminates the need to source and fit a barrel, recoil spring assembly, and sights separately, saving approximately 45-60 minutes of build time for experienced assemblers.
How does the P80 Slide Assembly compare to the generic Zaffiri Precision G19 slide?
The P80 Slide Assembly provides better out-of-the-box compatibility with PF940v2 rails than many aftermarket G19 slides, eliminating the need for rail channel fitting. Where a Zaffiri Precision G19 slide may require sanding or filing of the polymer rail channels on a PF940v2 frame due to tighter tolerances, this assembly is machined to specific rail geometry that matches the P80 frame's dimensions. However, the Zaffiri slide offers more aesthetic milling options, while the P80 assembly is a utilitarian, functional component.
What does it weigh and what are the dimensions?
The complete slide assembly weighs 14.7 ounces and measures 6.85 inches in length. The width across the slide is 1.0 inch, which matches the standard G19 profile for holster compatibility. The included threaded barrel has a thread pitch of 1/2x28 TPI, accepting common 9mm muzzle devices.
Who is this NOT for?
This assembly is not for users seeking a custom-milled, lightweight competition slide or those building on compatible frames like the Polymer80 LR-308 80% Lower Receiver. The finish is a standard, durable OD green Cerakote, not a premium nitride or DLC coating that offers higher lubricity. Builders wanting a completely bespoke look or enhanced slide serrations should consider a bare slide and custom barrel combination instead.
What's in the box?
The box contains the complete slide assembly, the Ameriglo GL-429 suppressor-height night sights, a stainless steel threaded barrel, and a captive recoil spring assembly rated for 115-147 grain ammunition. It does not include installation tools, a channel liner installation tool, or thread protectors for the barrel, which must be purchased separately if needed.
Is the P80 Full Size Slide Assembly worth it at $415?
At $415, this assembly is worth it for builders prioritizing guaranteed compatibility and time savings over customization. Sourcing a comparable slide, quality barrel, and night sights separately typically costs $380-$460 before shipping, plus additional hours for fitting and sight installation. The value is in the pre-assembled, test-fitted package that reduces build complexity, especially for those following technical procedures like those in The Complete Guide to Adjusting Slide Stop Tension in Spectre Kits.

Pros & cons
What works
- Weighs 14.7 oz – balanced for the PF940v2 platform
- Includes Ameriglo GL-429 night sights, a $90 value if purchased separately
- No rail fitting required on PF940v2 frames – saves ~45 minutes of gunsmithing
- Threaded 1/2x28 barrel included for suppressor or compensator mounting
Trade-offs
- No optic cut – adding an RMR cut costs $150+ and takes 4-6 weeks
- Finish is Cerakote, not a more durable nitride or DLC coating
- Recoil spring assembly is standard weight, may need swapping for heavy competition loads
- Does not include a thread protector for the barrel

Frequently asked questions
- Is it compatible with standard Gen 3 Glock 19 holsters?
- Yes. The external slide dimensions match a standard Gen 3 Glock 19, measuring 1.0 inch in width and 6.85 inches in length. It will fit most Kydex and polymer holsters designed for the G19, though holsters with extremely tight sight channels may require slight modification for the suppressor-height Ameriglo sights.
- Does this work with aftermarket RMR plates?
- No. This specific slide is not cut for an optical sight. It uses the standard Glock dovetail footprint only. To mount a red dot, you would need to have the slide milled by a service like Jagerwerks or buy a slide that is pre-cut for an RMR/Holosun footprint.
- How long does shipping take?
- Standard processing time is 1-2 business days before shipment. Ground shipping typically adds 5-7 business days for delivery to most continental US addresses. Expedited options are available at checkout for an additional fee.
- Can I return it if it doesn't fit my frame?
- Returns are accepted within 14 days of delivery if the product is unused, uninstalled, and in original packaging. Because this assembly is intended for use with the PF940v2/PFS9 frames specifically, compatibility issues with other platforms do not qualify for return unless the product is defective. We recommend verifying your frame model before purchase.
- Does this include a channel liner?
- Yes, the firing pin channel liner is pre-installed. This is a critical component often forgotten by first-time builders. The liner is a polymer insert that prevents metal-on-metal wear between the firing pin and the slide.
