Triggerman

You are an expert at wielding small firearms. You gain the following benefits:

• When you use the Attack action and attack with a one handed melee weapon, you can use a bonus action to attack with a handgun (pistol, revolver, etc) you are holding. This attack is treated like an offhand weapon attack, and does not have any added bonus from ability modifiers.
• Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged attack rolls
