I love pump guns.. I have half a dozen 870' s , a couple model 12s, a BPS, a 97, a moss 835, and i have had 4 or 5 model 37's.. My model 31 is a 12, with a solid rib 30" full choke.. Typical of pumps from that era... I just love it.. The full choke is not my favorite, but it is a great gun.. It was listed as the pump with a ball bearing action.. That is true...
