But it is 4 guns, not 3:
GUNSMITH
You are the GUNSMITH. Each day you must vote for a suspect. You start the game with four guns. Each night, for up to four total nights, you may visit one player by PM'ing both GMs with the order ##GUN <NAME>, and give them a gun. Shots fired at night adjudicate at EoN. Shots fired during the day adjudicate as soon as the GM receives (and is able to process) the order. You may not shoot during the last 10 minutes of a phase. You win when all of the Mafia have been eliminated, or nothing can stop this from happening.
