I was in Wally World this evening picking up some ear plugs. I remembered reading in another post that Walmart had the 390 for sale way cheap, so I looked over the revolving gun rack and there was a 12 gauge 390 for 498. The fine print on the sales tag indicated that this gun went on sale in 2003. I got a hankerin' to get an autoloader, but I'd like to know a little more about the 390, like what a 391 got that a 390 ain't (other than the 1).

Any info. on the 390 is appreciated. I've never bought a gun from Sam before, not sure if I want to start.
