I've got two for you. Try TT Gunleathers OWB Elite DDO Snap Holster. Have one on order for my 3" 686 CS-1. This will be the 4th holster I've purchased from Tim and they are well worth the money and 6 week or so wait.
Great quality, great guy and a great holster. He is the ONLY holster maker I know of to offer a 10% discount to Military, LEO's and EMS workers.
If you want a good holster and want to save a little money, Lobo Holsters make a very nice holster for your 686. Have an IWB from Ken for my 3" 60-10 and for the money it's hard to beat.
Both gentleman are fantastic to deal with and I highly recommend both of them for a rig that 686 would love to reside in.
