I love them all, but if I had to pick just 1 favorite, I would have to say my old Mossy 500 12ga. Have carried in in the field for over 30 years, in all weather condition, put 1000's of all types of rounds through it, and put lots of meat from pheasant to deer in the freezer. It has even embarrassed a few shooters at the skeet range. It's almost like it has become an extension of my arms. While it is a bit beat up, with many dings and scratches I wouldn't trade it for anything.
