If it helps :
A large number of Indian police, paramilitary and industrial and railway security force are equipped with Lee Enfield 0.303 bolt action rifles, 9 mm Sten Mk 1 sub-machine guns, and M1911 .45 Pistols. Go to an Indian bank or mall and the security guards are carrying 12 gauge double or single barrel shotguns, with paper cartridges with bird shot. They carry their ammunition in over the shoulder bandoliers with about 6 rounds. So an assailant can easily count how much ammunition the guard is carrying.
There is also an attempt to "AKfy " the single barrel shotguns by sawing the stock off and putting a fake pistol grip and fake magazine and brazing a fake gas tube on the top. This is to frighten an adversary into thinking the guard is armed with an assault rifle. The latch and the hammer of course are clearly visible.
