3D Printed FNS40 Prototype “Le Gros Chungus” First Test Shots
This guide details the initial test firing of the 'Le Gros Chungus' prototype, a 3D printed frame for the FN Herstal FNS-40 pistol. The process involves visual inspection, assembly, and controlled firing into a specialized trap at an indoor range to assess structural integrity and cycling reliability. The test was deemed successful as the slide locked back after the final round, demonstrating the functional viability of the 3D printed component.
