Well, just got back from the range and my test fire with the sear bar removed, toggle slammed shut, produced NO slamfires!!! out of 10 attempts,
and I think with 99% certainty, that it will not go off with a separated firing pin, as long as the front part isn't lodged in the breechblock for some un-known reason?? I also tried it a few times with a cartridge in the chamber and a direct impingement of the pin on primer in a slam fire condition, same results.. no bang.. BUT, it did mark the primer in every instance, just as I surmised with AR type firearms... So, there you have it boys! Can't go off unless the firing pin drops from a sear release.....
...Best to all, til...lat'r....GT
