Buddy found a Smith and Wesson holster by Bianchi and brought it to me. It has no indication of what models it fits. It has S1306 and #34 on the back. My 3inch 686+ fits in it with only an inch extra room for the barrel, but it is not made for a full underlug 4 inch barrel. I will attach pics soon as I can get them from phone to tablet. Any idea what models it was made for?
