9mm safety training ammo

thingiverse

Safe 9mm training ammo made easy. Simply take used cartridge cases, push the plastic, and a bit of sanding later, you're ready to go. Printing with 100% infill and 0.1 mm layer thickness without supports is also a breeze. Sanding is crucial so it won't get stuck in the barrel. A little extra effort upfront ensures smooth operation. For added safety, use a bold color to distinguish it from real bullets and make it easier to spot on the floor for re-use.
