Armed Services
Howdy Bill,
The answer is...probably not. Most military personnel who are issued a pistol are held to Condition 3 carry unless "Action is Iminent." That allows
for a pretty loose interpretation of the word, depending on the AO. If you're in a war zone, action is always iminent, or at least arguably so...but the carrying of a cocked and locked single-action autopistol would be heavily frowned upon at Camp Lejeune or Ft. Hood unless specifically directed or authorized, and only then under an alert or "Stand By" status.
The guys who were unauthorized to have a pistol, but lucky enough to scrounge one when I was in Vietnam varied in their preferred carry mode...
but most opted for Con-2 with the pistol tucked away out of sight. Open
display of a pistol was often a sniper magnet. I had one, and carried it in Con-1 in either a cobbled-up rig that was slung almost horizontally across my chest, or tucked into my waistband "Mexican-Style" under a shirttail with a length of parachute cord that was tied to make a sort of slide holster...again, depending on where I was and what I was doing. (Different story) I knew enough about the gun to feel confident in that mode, but very often returned it to 2 as soon as I was far enough from certain areas...mainly to keep from upsetting anybody that might catch sight of it. When night fell, back to 1 it went...no matter where I was.
EDIT:
Whoops! Just noticed a typo in the initial paragraph. Should have been:
"...Held to Condition 3 carry." (Hammer down/Empty chamber)
