Back in the day: 210 rounds issued, or 120, depending on posting (USAF Security Forces).
Now, LE patrol, city but with mixed rural due to zoning... G21, 2 spares on the belt. BUG and a spare in pocket. AR, 30 in the gun, 60 more on PC in front seat. Bought PC, rifle and ammo myself. Slowly adding more ammo, eventual plan is 90 on the PC plus 1 pistol mag. Transition to a 17 this yr or I'd have done it already.
