Close-Range Gunner

Your experience with using firearms in melee combat has made you an expert in close-range firing.
Being 5 feet of a hostile creature doesnt impose disadvantage on your ranged attack rolls.
Your firearms become an improvised melee weapon that you are proficient with. On a hit, it deals bludgeoning damage equal to 1d6 + your Dexterity modifier. If you make this melee attack as part of your action, you can fire with your firearm as a bonus action.
You have a +1 bonus to firearm attack rolls against creatures within 15 feet of you.
