Sharing my dumb build (Far Cry 6)

Karoche chose such a weapon setup, the Flare Gun (in this slot it changes to a bow or a rifle if stealth), a Machine Gun with a box of cartridges, a Shotgun with 15 rounds and single loading.
This is quite a lot of firepower, the problem is that if you shoot from all this arsenal, then reloading will take 30 seconds (like a ship in the ward of warships).
We just put a light SMG-11 type item in the fourth slot and stick into it the perk for reloading all weapons after reloading this item.
Well, we shoot our entire arsenal, and then we take out the sub, we make a short burst, a quick reload and voila, everything is ready to fire again.
I realize this is unrealistic, but I have died too many times painfully reloading my shotgun as enemies keep spawning.
