There are policies that vary by branch. The USAF, for example, carries the Beretta M9 pistol (Not sure when they switched to Sig? Must be recent) with the safety off, and in double-action mode. So, round chambered, and a single (hard) trigger pull (Or a manual cock + light pull) will fire the round. Dropping it should not fire it.

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.
