Hoffman's has been having some good deals lately. I've never been there but on another forum I frequent we have a New Englander's section with a lot of Connecticans who post stuff about Hoffman's.
With that said, sounds like a great deal. Last year I found a bunch of pristine, I mean not even holster wear, police-trade in Gen 3 Glock 22s with three mags and cases for $250 at Manchester Firing Line in Manchester, New Hampshire. If it wasn't for me living in New York at the time (wasn't an LEO at the time either, so no 15rd'ers) and having to pay almost $100 to get it into my hands, I wouldn't have been able to get my wallet out fast enough.
