With the introduction of several SMG’s, as well as nerfs to Shotguns in the past, most players end up being frustrated with shotguns and would rather use an SMG is close-quarter combat, especially when there’s a equip time delay.
Regarding shotgun equip times: current thinking is to reduce Pump Shotgun equip time slightly in update 5.30 next week. Other shotguns will remain unchanged for now
