If you've been thinking of getting one of these, now's the time to do it. I just talked to Mr Vang; he's purchased a large quantity of the 18.5in. 6-shot Mil-spec 590A1 and they're priced to move.

BTW, I took mine to an indoor range the other day; I didn't even notice any extra flash from the porting.
