Hmm, I chose my name after an old British made revolver and the calibre it used. I collect firearms and have a federal collectors license. It sounds impressive, but it is easy to get one if you're a responsible citizen. First got into forums about guns so used it among them kinda kept it cause haven't seen any others using anything similar (have seen people use the Webley part- everyone always goes for the modern models for names).
The cool thing about collecting guns is that the wife won't complain if I buy lights instead, it's LOTS cheaper of a hobby.
