Nicholas, can you let me know if I'm handling the "Well-Aimed Shot" combat action correctly
For purposes of determining if you hit, there is a -20 to the OB. So in Gribbles case he ends up with a 14 after all modifiers are taken into account.
For purposes of determining damage, I wouldn't have the -20 applied, so the damage roll would become 34, plus I would add another +10 to the modifier for weapon size, giving a total of 44. Is that correct? (Plus if he rolled higher he could actually exceed the maximum damage cap by 10)
Also, the text for Two Gun Combo says that the penalty for the weapon in the off hand is -20, but the example seems to indicate that it is -25. Since Robots have the Ambidexterity Talent, they ignore the penalty anyway, so it didn't affect the combat.
