William F. Cody named his Springfield .50 caliber trapdoor “Lucretia Borgia.”
I've seen names of rifles like "ole Betsy, Marge, Widow Maker and Buckworth to name a few.
As for me I christened my High Wall Quartrefoil, the ancient meaning for good luck.
How about you?
BTW my pickup truck is named Maggie M'gill. LOL
