Firearm's Expert

Prerequisite: Dexterity 14, Firearm’s Specialist and/or levels in Gunslinger archetype

Thanks to extensive practice with firearms, you gain the following benefits:

• Increase your Dexterity or Wisdom Score by 1. 
• When you use the attack action with a one-handed weapon, you can use a bonus action to attack with a one-handed firearm you are holding. 
• You learn one trick shot of your choice from among those available to the Gunslinger archetype in the fighter class. If a trick shot you use requires your target to make a saving throw to resist the maneuver’s effects, the saving throw DC equals 8 + your proficiency bonus + your Wisdom or Dexterity modifier. If you already have grit points, you gain one more; otherwise, you have one grit point. A grit point is expended when you use it for a trick shot. You regain your expended grit point when you finish a short or long rest.
