Limit the max ammunition in weapons is not necessarry if criminals spend half of the time getting arrested, unless you want to limit ever ygun to 1000 ammo, then that would make more sense.
Still, unless you have more ways to obtain weapons/ammo other than supply drops then maybe.
Nobody can escape their sins, everyone gets punished whether it takes a day or an eternity.
