FIST holsters makes their kydex holsters for 686 in all barrel lengths.
Here is a picture of one I had for a Ruger LCR. Very thin, very light,
but also very tough. This particular model was IWB model 1K.
Check out MK-Tek. They list the 686 2 1/2" on their mold list and they make excellent holsters. The owner and I served in the 3rd Ranger Bn. together back in the day.
OP, you didn't specify OWB or IWB, but if IWB, go JM Custom Kydex. One of the best in the business, and their IWB 3 for L-Frame 2.5" is available for quick ship.
