I would say to use something with your name in it, but it's freakishly long and no one would ever type it in correctly.Hmm, hard to believe that "customfirearms" isn't taken yet. Too generic for my liking though.
I do have an issue with people using too cute of names for their web address. While it's funny at first, it becomes less funny each time you use it.
