Stealing from PD's armoury
There can be an Armoury in each PD interior which people can rob, like the bank and deliver to hideouts. The payment can be higher, the cooldown can be longer, and it can be challenging a bit to not cause more inflation, for instance needing to put the weapon items in your trunk or something? Or like when two cops are online atleast? IDK
The hideout can be divided from bank hideouts, it can be a ped standing somewhere that buys your stolen weaps from you. Or whatever.
Any suggestions?
