So I decided to cruise the used gun racks at my local Cabela's after I got off duty today and came across what looks to be an older police variant of the M37 (18.5 in barrel/8 round mag with standard stock) in pretty good condition for about 350 bucks. Anyone here got any info on if this is a good deal and how well an M37 shapes up along side a Mossberg 500 or Remington 870 in terms of function?
