I don't turkey hunt so my experience is with deer shotguns only. I have a Remington 1187 and a 870, both with field barrels and slug barrels. I also own a older Mossberg 500 with the same set up. I just added a 50 cal muzzle loader into the mix too to try this year deer hunting........Who the hell needs 4 different guns to hunt deer with?? Me I guess

. Either the 870 or the Mossberg model would work fine. I don't know much about the newer Mossbergs but my 500 shoots good. If I had to pick a "go to" gun it would certainly be the 870. A little higher priced than the Mossberg but it will last you a lifetime. Let us know what you end up getting.
