If you cause a misfire, you can instead choose to take 1d4 lightning damage and unjam the weapon with a bonus action instead of an action.

When you roll an attack roll and the dice roll, before modifiers, is equal to or lower than the weapon’s misfire score, the weapon jams. A jammed weapon cannot be used until you use your action to fix the weapon’s malfunction.   Firearm Ammunition. The ammunition used from a firearm is destroyed upon use. All firearm unless stated otherwise use bullets.
