I've been strongly considering carrying in condition 0 as a matter of course. Why? Well, why not?
My other guns are an XD and an M&P. Marketing buzzwords aside, these two pieces of tupperware appear to be single action, striker fired weapons with firing pin block safties, some kind of trigger widget, and in the case of the XD, a grip safety.
It seems to me that my series 80 1911 in condition 0 is about the same thing as either one. I don't stake much on the trigger widget, much less so the hinged trigger on the M&P.
When safely holstered in a trigger-covering holster, the trigger can't be pulled. In the very unlikely case of a sear malfunction, there is BOTH the series 80 FPB and the half-cock shelf to stop the hammer, so nothing will happen. EVEN IF the holster is somehow punctured in the trigger area, or the gun falls out and tragically something gets caught in the trigger gaurd, nothing will still happen because of the grip safety. If I pull it out of the holster and pull the trigger, it will go bang.
Tell me, how is a condition 0, series 80 1911 substantially different than my M&P? You can see that scary exposed hammer? The M&P doesn't even have a grip safety.
