I have a very nice 686, 4 in barrel. CS1 stamped gun for sale. it has the 2M stamp which from my research shows that it was most likely an issued gun that was carried by a customs officer. The gun has a set of refinished combats that had a crack down the middle. The crack was fixed and will hold up nicely also included is a set of conversion pachmyers, round to square butt. shipping 25$. 1300 obo on the entire package.
