I love mine as well. Added a pistol grip stock and a shell holder on the stock. It runs through 3" magnum shells, slugs, 00 buck ... no issues at all. I actually like the safety position on it better than the 500's also.
Any of the normal Mossberg 500 accessories fit (stocks, barrels, etc..) except for the forearm, so you have a wide array of stuff available for it.
