I use a handed down Pump 870 from the early fifties. I never saw any reason to upgrade. It kills turkey as well now as it did for my grandfather. LOL. I did finally trade my old .270 in for an mostly aluminum BLR .243 for deer and love it! At just under 8 Lbs. it never wears you down in the forest.
I love the 870s just as much as I love the Mossberg'*. Never had one handed down to me though, or I would just use them Ha.
The Mossberg Revelation is not a pistol grip shotgun. And looking back at your pic it isn't a custom grip but just a hacked OEM one. Either way in Michigan custom or hack, it is now considered a pistol in MI and you now are in possession of an unregistered one.
i dont know what it is lately with shotguns.. ive always liked guns (in a countryboy/redneck kinda way, not a thug/gangster way) i want a few rifles and maybe a nice hangun or two too but i dont wanna go threw the hastle of registering em, so ill get my fill of shotguns first, then start getting into rifles and handguns
