Condition 0 is not dangerous, if in a good holster and carried by an experienced person - there's at least 3 safeties still engaged at that point - the grip safety, the holster covering the trigger guard & trigger, and my brain. Less than no chance of ND in that circumstance. Zero or 1 are the only ways to fly. IMO.
Doc,
Please tell me that theres no reason to carry a 1911 in your holster with the thumb safety disengaged?
also please tell me that youve never carried it this way?
