My maverick is pretty much the only shotgun I've used so I don't know how it compares to other pump guns but...

I've had mine for over ten years now and it still operates without a problem. This gun has seen a lot of use and abuse (ie. it's me ands Dads winter saltwater hunting gun: saltwater, freezing temps and banging around in an open boat).

It's reliable and cheap enuf that I never feel the need to baby it in the woods or the boat.
