Custom Polymer 80 Improved Mag Release (G17/G19 compatible)

thingiverse

My p80 PFS9 pistol was dropping mags because the mag notch was worn, the p80 magwell is loose, the mag release spring was weak, and the spring was so long it pushed the release into the frame, adding friction/stickiness to movement. I got a new spring and designed a mag release based on the glock 17 extended model, but added an extra 1.4mm of lip on the mag catch, and shortened the pocket in which the spring sits to increase its applied force. You can go into the step file and modify the lip offset for your own purposes, just remember that the two dimensions at either end of the offset must be deleted before changing the offset, then must be redefined to accomodate your new offset. Print @ 0.15mm layer height. No support needed, but I always reccomend brim of 10 lines or more. Sand the top/flat surface and make sure there is no brim left before installation.
