About this product
A Polymer80 handgun is a customizable 80% polymer pistol frame designed for enthusiasts and builders seeking a personalized sidearm platform. Its front and rear angled slide serrations, thumb/accelerator cut, and double-undercut trigger guard facilitate enhanced handling and modification. This frame serves as a foundational component for constructing a functional firearm through user-completed machining steps.
What is the Polymer80 handgun used for?
It is used for building custom pistols from an unfinished frame that requires user milling to legal completion. The frame accommodates standard Glock-compatible slides and parts, allowing for tailored ergonomics and performance. Ideal for DIY gunsmiths and hobbyists who value customization over off-the-shelf options.
How does the Polymer80 handgun compare to the Polymer80 PF940V2?
The Polymer80 handgun features a more aggressive serration pattern and double-undercut guard, whereas the PF940V2 has simpler serrations and a standard guard. This model provides better grip traction and comfort but requires 20% more milling time due to its design complexity. For detailed modification tips, see the Best Drill Bits for Polymer Frame Modifications.
What does it weigh and what are the dimensions?
It weighs 12.8 ounces and measures 190 mm long by 140 mm high by 32 mm wide. The lightweight polymer construction reduces overall pistol weight when assembled, typically resulting in a finished build under 24 ounces. These dimensions align with compact pistol standards, ensuring compatibility with most holsters and accessories.
Who is this NOT for?
It is not for beginners or those seeking a ready-to-fire firearm without tools or expertise. The frame requires precise drilling and milling with a drill press or jig, taking approximately 2-3 hours for completion. Individuals in restricted states like California should consult compliance guides, such as more on Calculating Polymer Frame Warranty Coverage Limits, before purchase.
What's in the box?
The box contains one 80% polymer frame, a set of four rail guide pins, and a small parts kit including springs and detents. No jig or drill bits are included, unlike the see Polymer80 80% Lower Receiver and Jig Kit, which bundles those essentials. Expect to source additional tools separately for completion.
Is the Polymer80 handgun worth it at $469?
At $469, it is competitively priced for a high-modification frame with premium features, though it excludes a jig. Compared to finished pistols costing $500-$700, it offers customization savings if you own tools. The investment pays off for builders aiming for a unique, performance-tuned sidearm without factory limitations.
