You can use intelligence instead of dexterity/ strength for determining attack and damage rolls. As an action you can switch from one firearm to another. You can use your firearm as a spellcasting focus.

Reload. The weapon can be fired a number of times equal to its Reload score before you must spend 1 attack or 1 action to reload. You must have one free hand to reload a firearm.
