i found what it says about the MEU(SOC) 1911a1:
"the m1911 was much liked for it's reliability and lethality, but it's single action required it's users to be thought familiar with it. As a result accidents did happen and orders were given for it to be carried without a round in the camber, bur even so unintentional dischargers were frequent occurrences."
i sum up what it said. If the United States Marine Corps, MEU(SOC) and reconnaissance units (they said there the best of the best)that all carred these guns were haveing problem like that with a gun then i would carry a DA just to be safe.
