Nowadays, the profession of Ranger mercenaries is illegal within the scope of the Great Tang Group's power, and carrying weapons is a serious crime, as the gun ban is very strictly enforced.
To carry firearms into core areas, such as Wolf City and Brunas, is even more difficult. Under normal circumstances, bodyguards and the like must declare their firearms, and many key locations even prohibit bodyguards from entering...
However, despite the strictness, there are still those who carry weapons, such as swords, flintlock guns, and some who carry Left-Wheel Handguns.
The world is in chaos these days, so there are many who carry weapons, and indeed managing this is quite troublesome for the Great Tang Group. Therefore, it's unrealistic to expect checkpoints to detect every weapon being carried by an individual.
