I've had a 31, an Ithaca 37, some 870s and some 12s. I still have two 870s and five 12s. I shoot the M12 and 870 interchangablyI have kept a fifties vintage 7 diamond forend 870 and 1915 solid rib M12 because they shoot better than anything.I don't think it gets any better though than a full dress M12 with high grade walnut and a nice blue job. You can't touch the function or the looks.
