What are the attributes for the Hi-Point firing pin springs. I have read in another website about a cartridge firing while cycling live ammo due to the firing pin being use to eject a live round. This seems probable but unlikely since pressure and penetration is based on the speed and psi of the firing pin hitting the primer. A typical firing pin spring has the following attributes. - Protrusion should be about 0.055" (.040 to .060 acceptable) - Firing-pin spring pressure about 20-25 pounds. - Firing-pin penetration should be about 0.020". I have cycled live cartridges through my Hi-Point pistols and not had any discharges during extraction. Has anyone experienced this premature discharge during manual extraction?
