I'm not sure about a 2 1/2" model 66LS but I own a model 65-5ls, seen here with Hogue rubbers.
I took the rosewood combats off and put them on my model 66-2.
The model 65LS is a great CCW piece and I often wondered why they only made this configuration in the LadySmith version. I like the shrouded ejector rod better than the exposed.
