If you read Joe Perry’s autobiography, he talks about growing up hunting small game. He also mentions I believe, a custom flint lock rifle and hunting with it later in life.
Didn't the band get in trouble several years ago for having a bus full of cool guns in a jurisdiction where such things are frowned upon? I can't find the article at the moment, so maybe I'm hallucinating.
I also believe that Perry and Tyler got wrapped in some sort of controversy around NYC gun permits.
