Westerns and Such
I grew up watching westerns on TV. I don't really care about horses but I do like guns and tough guys. I like reading articles by Sheriff Jim Wilson, who is my favorite gun writer. He was a Sheriff in Texas and is a guy who likes revolvers too.
This is my western outfit with my RCMP duty holster and S&W M19 "Combat Masterpiece."
I would guess that the vast majority of guys my age have been influenced greatly by the cowboy movies and TV shows they watched while growing up.
