    With the scarcity of standard pistol primers, I've talked to some long time reloaders that have used Magnum small pistol primers, and just make sure they start with the minimum load and work up if needed.


    Anyone here done this with success on their P3??

    Thanks, Ned.

    You can do it safely if you work up from a starting load, watching for any sign of case bulging at the feed ramp cut.

    The only possible problem you might encounter is if the mag primer has a harder cup.

    In that case, you might run into miss-fire problems with the light primer strike of a P3AT.

    Only way to know is to try it.

    Devil's advocate: What about cutting a few coils from the FP spring to get a firmer strike on the magnum primers?

    NO, don't do that.
    That increases to risk of a ND from dropping the gun.

    Better yet, just keep searching till you find some Sm Pistol primers somewhere and use what you are supposed to use.

    I thought so but I just had to ask. You never learn anything if you're afraid to ask. And yes, that also includes "stupid" questions. ;)
