yea, its a good deal. Just depends on whether or not you want the gun, but you're not likely to find better pricing (in fact, I think that's cheaper than LEO pricing).
That said, I passed on a Like New Gen 4 27, 4 mags, and night sights for $450 all in yesterday. As good of a deal as that was, $450 is still a lot of money, especially for a gun you don't "need". I did want the gun, but couldn't justify owning it with what I already have.
