I recently saw a Monson Model 15-2 in my local gun/sporting goods/pawn shop. It was a 98% specimen with the non-ventilated, half-underlug 6-inch barrel, blued, with original, wood stocks. This would be considered the standard, entry level Model 15-2. It had been sitting in the case for about 6 months with a $600 tag on it. I did examine it and it was tight, so used very little. I opened the negotiation at $450 cash, but was turned down. I would have certainly gone $475 and perhaps $500, given that it was in such great shape. Sadly, it was a consignment piece and I was told that it had a rock bottom price of $550 plus tax and background check, no further negotiations. I passed, but a couple of weeks ago either someone bought it or the owner took it back. These can be nice revolvers, but there is little factory support, especially when it comes to blued carbon steel parts. I am always wary, though, as some DW revovlers exhibit all the signs of having been made on milling machines that had cutters that were beyond their replacement interval.
Oh, and rubber stocks can "weld" themselves to the grip post. Rubber stocks can also allow moisture to accumulate and form rust under the rubber.
