I bought this used from a local store and it came with a tac light (grip activated), and a longer tube for 8 or 9 rounds I believe. Cosmetically it's in great shape (like new), and from what I know it sat in the previous owners safe most of the time.... I picked it up for a little over $800.00 Did I do good? Also I know that HK, and Benelli are in cahoots with one another but this particular gun had Benelli markings on the barrels and the left side if the frame (receiver) but on the right side it says Heckler and Koch??? Is this an early model? What gives???
