You are fully ambidextrous (at least while shooting) and can use both hands simultaneously with amazing coordination. You amaze even yourself with your ability to coordinate your moves so that you can keep ut a staccato beat of gunfire against multiple opponents at once.
You can fire at two separate opponents in one action with no penalty by using two different weapons, one in each hand. Make a separate attack roll for each. You may not attack the same target twice with one action; use BothGunsBlazing for that.
