Paladin (Holy Gun)

A holy gun can spend 1 grit point to make a smiting shot with a firearm attack as a standard action. If the target is evil, the holy gun adds her Charisma bonus and her paladin level to the damage of the firearm attack. If the target of the smiting shot is an outsider with the evil subtype, an evil-aligned dragon, or an undead creature, the bonus to damage increases to the Charisma modifier plus 2 points of damage per level the paladin possess. Regardless of the target, smiting shot automatically bypasses any DR the creature might have. This ability replaces smite evil.

At 11th level, a holy gun gains a number of grit points equal to her Charisma modifier (minimum 1) and gains the use of a single gunslinger deed. She can select any deed that a gunslinger of her paladin level –4 could use. At 14th level, and every three levels beyond 14th, the holy gun gains another point of grit and another gunslinger deed that a gunslinger of her level –4 could use. If she already has levels in gunslinger, she gains a bonus to the maximum amount of grit she can have each day, equal to her Charisma bonus (if any) but gains no extra grit as the start of each day.

This ability function like the holy champion paladin class feature, but the banishment occurs when she hits an evil outsider with the smiting shot deed.
