Id take the mossberg with a normal stock because I prefer their safety. The 870 with a pistol grip, because the Mossberg safety sucks for a pistol grip. The 37 is a fine hunting shotgun but would be a good ways down my list. Benelli, Browning, winchester (12) , maybe even HI standard flight kings would be before the 37 in my book.
Im a shotgun collector. But like others said, I wouldn't carry a shotgun on a stroll unless I'm hunting for fowl or rabbit or squirrel.
