Before I get into my question, I just thought I would do the standard "Hello, I'm a noob" thing. My name is Mike, I live in Columbus, OH. All that I own right now is an old ruger 10/22 and a Savage Arms over under single shot breakaction. Top barrel is a .22 mag and the bottom is a 20 guage. Now for my question - I'm looking to buy a 12 guage pump, but I'm a poor college student. Would there be anything bad about buying a gun at a pawn shop? I've been seeing tv commercials for one lately that actually looks to be fairly nice. I've never been in one before, so I'm not totally sure what to expect.
