This seems to suggest carrying with a chambered round. Is this prudent without an external threat? They can drop the thing, or some kind of impact can yield a “design problem”. Can’t they just chamber when there’s a need?
I had to carry one in my vest in case of emergencies, and I never felt comfortable being one trigger pull from bang, while it's pointed at my waist for extended periods. Also, the double-action pull sucks, and it's harder to aim straight when putting so much muscle into the pull IMO. Had to have the finger on it in a certain way to get leverage. (The single-action pull after doesn't have this issue)
So, I would accept the weapon from the equipment guys, insert the mag, send the slide forward, put it on fire since that's what you're supposed to do... then put it back on safe.
