I recently came across a gun on Armslist that is priced to perfection - maybe too good. How would one best identify whether the seller is legit? I know the usual caveats about buying sight unseen over the 'net. Have yet to have a bad experience on the 'Hide here - but that doesn't mean that there aren't crooks out there willing to take my money and run - but sometimes good deals do arise. Anyone ever gone thru with a little more due diligence in this type of circumstance?
