Got to pick the Mav, again, for parts concerns. I like the Pardner Pump, have been suggesting folks buy them for more than a year, but if you're in *this* forum, repairability and parts replacement is a key concern. If it's a second gun, go for the Pardner, but basic gun? It's a fool's choice.
The Pardner, based on the 870, has the same probs with certain key parts wearing and breaking....and the #1 part broken is the ejector spring, followed by the rivets holding the spring and ejector. None of which you can repair or replace yourself. As I just finished telling a guy in another forum, replacing those parts is a $75-100 gunsmith charge. Riveted parts are the bane of the 870 and all the 870 clones.
The Mav, on the other hand, the ejector is a $7 part and can be changed by you inside of two minutes by candlelight if need be.
The Mav shares all functioning parts with the Mossy 500 and parts are cheap and incredibly easy to replace. The Mav can be used for hunting or defense etc with the 30 second switch of a barrel.
