Handguns

There was, in the 19th century, an Italian Monk named Gabriel Possenti. According to a legend, Saint Possenti saved a village from a marauding gang of soldiers by scaring them off with his hand gun prowess. So that was enough for a group of handgun enthusiasts to form the St. Gabriel Possenti Society to lobby to get the Pope to designate St. Possenti as the Patron Saint of handgun enthusiasts.
