    Slam Fire In Rim Fire Pistols

    I recently bought a .22 conversion kit for my pf9 and it just came in the mail today so I have not fired it yet. They mention slam fire and list a precaution that states:

    Be aware that .22LR ammunition is prone to possible slam fire (unintentional fire on forward slide movement) due to differences in brand. Always point the barrel toward the target and let the slide forward gently to reduce the possibility of slam fire occurrences.

    I can see how this could possibly occur, but it also seems that it is a normal function of the battery to have it slam forward to a firing position. So what's to stop it from slam firing during normal cycling? Or is this just a CYA from the manufacturer ? I only have experienced rifle and revolvers in .22 caliber so I am not familiar with semi-auto in that caliber.

    Thought's ??

    The only way that I could see a slamfire, was if the hammer was not being held back by the sear. And then, maybe....

    No such warning with my SR22. Probably a CYA deal. Is it a factory kit or aftermarket?


    Edit: Shouldn't the warning be...

    Due to variations in ammo production, this could instantly go full auto. Hold on tight!

    I had my Buckmark go full auto due being extremely dirty. My nephew was shooting it at the time and wanted to hand it back to me while it was still emptying the mag. I was glad it wasn't hi-cap.

    Think I will stop cleaning my Buckmark. Never had it happen in pistol (2) or rifle (4) and we shoot a lot of 22lr on the farm.

    I've seen a couple of .22 rifles slam fire. There are probably many ways it can happen, but one way is if the the gun is so dirty that a sub-minimum headspace condition arises.

    Me I be very very leary of a gun that is watned could slame fire esp guns that are easy to convet to full auto.. Way too much attation if oyu know what I mean

    Anyhow my guess a issue with the firing pin and disc/springs be over powerder by hot hot rounds and not locking after firing .. Course this can lead to a out of battery issue

    My Advantage Arms .22 conversion for my Glock has never done it, but in truth, it needs to be cleaned after @100 rounds or it starts misfeeding.

    Anytime you cycle "ANY" auto loader there is a possibility of a slam fire, it is a small possibility but it is always there.
