Have a chance to buy a K-38 Masterpiece Stainless Revolver Model No. 67. Just copied that off the paper work that's how I know. What sort of quality is this particular model? The serial number reads AHW2427. I am thinking about buying the revolver just to have around the house for a little defense backup for my Mossburg 20 gauge. My friend is asking $325 , is it worth it?
