Gun Firing Pin Fit: GunTech #14 - In the Classroom - YouTube
The speaker says that if the firing pin fits sloppy, is too long, or is too pointed, the primer can spring a leak, and gasses from the cartridge case can flow backwards.
When this happens, he says that if you are not wearing glasses and you don't have a modern gun that has some kind of gas deflection system in it, the gases can go in face and burn/blind you.
What gas deflection system does Ruger use in the Mini?
