Polymer80 PFS9 Complete Pistol: Build-Ready 9mm Performance

This is the complete, ready-to-assemble Polymer80 PFS9 frame kit. You get the core of a serious 9mm handgun, designed from the ground up for a superior grip and shootability. It’s not just another frame; it’s the foundation for a reliable, accurate pistol built exactly to your preferences.

The heart of this kit is the patented Polymer80 frame in Flat Dark Earth. We’ve handled it here, and the aggressive texturing is no joke—it locks into your hand. The 1911-style grip angle points naturally, and the double-undercut trigger guard combined with the extended beavertail gives you a high, comfortable purchase. Your support hand gets a solid seat on the textured accelerator cuts. The flat-faced trigger provides a clean, consistent press.

This is a full-size platform, built around a 4.49-inch barrel and a 17+1 round capacity. The matching slide is a tough Black Nitride-coated stainless steel, featuring front and rear angled serrations for positive manipulation, whether you’re press-checking or charging. The internal fire control parts are pre-assembled in the frame’s serialized chassis (FCU), making final assembly straightforward with basic tools.
