I have a chance to buy a Model 10-4 which is in probably 90-95% shape and it has a 2" barrel (VERY short, I don't think it even makes 2.5"). It looks a LOT like a Chief's Spl., except for the 6-shot cylinder. It is pre-lock, pre-MIM. Serial number starts with BPB (I presume the late 90s?). He wants $325 for it. Should I pick this one up?
