No doubt you're talking about the M37, my 500 may be less pretty and from the wrong side of the tracks but she "puts out". She's also not the only girl in town who can be had for $125. This 37R has a 30 inch barrel with a solid rib and 40 line per inch checkering that runs over the top of the receiver to the front of the trigger guard. They don't make 'em like that anymore.
Actually I bought both from a friend who gave up murdering deer and birds. I have no use for either of them as I don't hunt (don't mind if you do though) but I can't pass up a good deal. Especially where 12ga pumps are concerned.
