Extremely common, Glenn.
Either by office or agency policy (not sure), we're prohibited from using those combo cuff/single mag pouches. I guess the idea behind it is that they're very convenient and if they were allowed then people would be more inclined to only carry 1 reload, instead of two. The real effect is that when doing office days, the "target population" simply carries the gun and badge instead of at least having a reload. Counterproductive, IMO.
It's not uncommon for local/state guys* to join us on medium and high threat protective details carrying nothing but a badge and gun. This, on a mission where a good portion of even our not-tacticool/not-gun-guys bring extra mags in their bail-out bag, a full IFAK in addition to the med gear on their person (most carry at least a TQ), etc.
*Except for the NJ State Troopers. Those guys are pretty much always ready to party whenever, wherever.....
