Yes it is. The tube on the 590 is 8 shots.is the 590 what the military use? I keep getting the 500 and 590 mixed up? The one I am looking at only holds 4 shots and I am looking to extend it to 7 or more since it has a 28 inches barrel.
I remember my 870 was extremely easy to add the extension to the magazine tube; just unscrew the cap and add the much longer one. I didn't and still don't like the safety position of the 870 and the folding stock was long for me so I sold. It would cost me money to get a stock I want and I'd end up having an extra stock I may not be able to sell. It would be wiser to get a complete gun of a setup I like so now I am looking.
The 500 holds five in the tube and one in the chamber. It's a 5+1 gun. If the one you saw was four, it's got a plug in it. It can't be extended beyond 5+1 as it is, though. To do that, you'd need to switch the barrel and mag tube for a 7+1 Persuader barrel and tube or an 8+1 590 or an 835 barrel and tube which allows extension tubes or a 5+1 590 that allows extensions etc.is the 590 what the military use?

Suggestion... Go for the 590; the barrels are thicker and the gun is made to mil-spec. Indestructable, will last 3 lifetimes & has the "feels great" quality...
that's nice but that's more than I paid for my 500 hahaThese will turn your 500 into the security or higher cap model 500
