If you have a Shotgun and a handgun equipped as your weapons, Lead Storm will always fire with the pistol.

To clarify, I had:

Corvis Cannon as weapon
Quickdraw as hand slot

I used leadstorm and it shot with the quickdraw. I swapped the gun order (Quickdraw weapon slot, Corvis Cannon hand slot) and it shot with the quickdraw. I used ambidexterity and it only shoots with the quickdraw. If I take the quickdraw OFF and have no hand slot, it finally shoots the shotgun.
