About this product
The Polymer80 PFS9 Compliant Pistol 9mm is an 80% polymer frame kit requiring user completion for a functional handgun. Production has been temporarily halted, making remaining inventory final sale. Cryptocurrency payment is strongly recommended for privacy protection.
What is the Polymer80 PFS9 used for?
The PFS9 serves as a build platform for a custom 9mm pistol requiring user completion of the 80% frame. It appeals to enthusiasts seeking hands-on firearm assembly experience without serialization. The completed frame accepts Glock 19 generation 3 slides and components.
How does the Polymer80 PFS9 compare to the Polymer80 PF940V2?
The PFS9 offers a more compact profile than the PF940V2, measuring 1.2 inches shorter in overall length. It better suits concealed carry applications but sacrifices rail space for accessories. The PF940V2 maintains superior aftermarket compatibility for tactical upgrades.
What does it weigh and what are the dimensions?
The unfinished PFS9 frame weighs 8.3 ounces with dimensions of 6.7 inches long, 4.9 inches tall, and 1.2 inches wide. Completed with a standard slide and barrel, total weight averages 22 ounces. These metrics place it squarely in the compact pistol category.
Who is this NOT for?
This kit is unsuitable for beginners lacking machining tools or gunsmithing experience. The frame requires approximately 3 hours of milling, drilling, and finishing work. Individuals seeking a ready-to-fire firearm should consider our completed LR-308 lower instead.
What's in the box?
The kit includes one 80% polymer frame, one locking block rail system, and one rear rail module. All necessary jig components and drill bits are provided for completion. No slide, barrel, or fire control group is included—these must be sourced separately.
Is the Polymer80 PFS9 worth it at $479.99?
At $479.99, the PFS9 commands a 35% premium over standard Polymer80 frames due to its discontinued status. This price reflects collector value rather than functional superiority. Budget-conscious builders should consider the 80% Lower Patriot Pack for higher volume efficiency.

Frequently asked questions
