    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?

    I have not experienced it (premature discharge) with my Hi point that I use for plinking at the range, but I have noticed some light pin marks that is maybe a couple of thou deep in my live rounds that I have ejected before. That and a few other reasons is why I use it for cheep plinking and not a carry weapon.

    I hope it doesn't result in a paternity suit.

    I never experienced that problem.
    Premature discharge during cartridge insertion I could see, but never extraction.

    The OP is talking about when you pull a live round out of the chamber in the unloading process. When you do that with a Hi point the firing pin sticks out to push the round out of the extractor claws.

    This is something I haven't seen mentioned about Hi Points & may change my mind about owning one. That sounds like a design that is almost as bad as having to pull the trigger to field strip a pistol! ;)

    Sorry, couldn't help my self.:eek:

    Actually, the only time I eject a live round is when I unload the SD ammo in one of my pistols to take it to the range for practice & since my Hi Point would strictly be a range pistol, it'd not be loaded with SD ammo.

    As you say, the Hi-Point is designed so that the firing pin is the ejector. So if you rack the slide manually to eject a live round, you have the firing pin striking a live primer. But unless you are superman and rack that slide extremely hard, I can't see it hitting the primer hard enough to detonate it. Which would be all the more difficult due to the very heavy slide and recoil spring on those guns. I have seen ejected live rounds with a very slide ding in the primer, but no where near what it would take to fire it.

    Yep. Like I stated in my earler post The marks I have seen in the rounds are only a few thou deep.
    I agree with you Paladin, was just stating the fact for the OP
