firing pin stop
Please indulge my skepticism,the firing pin strikes the primer and it's immediately
pushed back and cannot lose inertia since the slide is going back as well.In addition to that the primer depression is about +-1/32 so it doesn't seem possible that the firing pin can be unsecured to the slide long enough to cause that failure.A mechanical defect eg. broken or tampered with spring would of course but even a +P is too far fetched.I go to the basics when in doubt and
my Rand's firing pin stop is loose and I suspect that all those pistols soldiers
carried to war had the same fit,so the way I see it this is an issue that sells
a $20 tool to free a part that is not designed to be pried lose.
