About this model

A printable small and large rifle or pistol primer. These are good for safe firearm function testing, they allow the gun to be dry fired against the plastic primer. After snipping these apart, I used a Lee hand primer to load these into my 9MM dummy rounds. I used eSun PLA+ ( in orange so they could easily be identified from live rounds.
