Pistol-Whip

At 3rd level, the gunslinger can make a surprise melee attack with the butt or handle of her firearm as a standard action. When she does, she is considered to be proficient with the firearm as a melee weapon and gains a bonus on the attack and damage rolls equal to the enhancement bonus of the firearm. The damage dealt by the pistol-whip is of the bludgeoning type, and is determined by the size of the firearm. One-handed firearms deal 1d6 points of damage (1d4 if wielded by Small creatures) and two-handed firearms deal 1d10 points of damage (1d8 if wielded by Small creatures). Regardless of the gunslinger's size, the critical multiplier of this attack is 20/×2. If the attack hits, the gunslinger can make a combat maneuver check to knock the target prone as a free action. Performing this deed costs 1 grit point.
