Have you shot a .357 Magnum? Big fun and big power without big kick. Easy trigger either cocked or double action. Flames shooting out and around the barrel. But that's not why you're here.
You're here because this six letter domain name representing a famous firearm is priced to move fast at . You can build a website about .357 Magnum revolvers, or firearms in general, or pretty much anything that appeals to the macho crowd. Or, you can treat it as an investment, wait a year or two to get your price, and make 10x or even up to 100x what you paid for it. But good .com domain prices do nothing but go up, so if you're interested, get it now, or you'll be buying it from the guy who bought it from me.
