I consider them females. I think PWN375 over on AR said it best when responding to a question posted about what to name a new rifle.
He said He'd name it for his ex-wife. She was beautiful, almost impossible to control and killed everything she came in contact with!

As for me. I am tempted to name mine after an executive producer who knew everything, and couldn't do shit. However I don't want to insult the rifle like that!
