Started building custom P80 frames as a side project while working in precision machining, eventually turning it into a full-time career focused on fitment and reliability. My practical approach comes from 6 years as a bench technician at a regional FFL where I handled hundreds of Glock-style platforms and encountered every tolerance stacking problem imaginable. Now I focus exclusively on demystifying the P80 build process through clear measurement data and repeatable techniques. I maintain that the difference between a range toy and a duty-ready pistol is often just 0.003 inches and the patience to verify it.
Areas of focus
- Polymer80 frame rail seating and hole alignment
- Slide-to-frame fitting for aftermarket assemblies
- LPK installation and connector tuning for reliable ignition
- Jig use and drilling technique for minimizing tolerance shifts
- Support-hand-only slide manipulation drills for verifying function
- Frame finishing techniques that preserve critical geometry
