Not answering the question, but a comment on customer service. The Ruger CS for revolvers had been outstanding (until they told me they had no more parts for my 1985 Security Six). Their semi-auto service is less than commendable (different location & staff).

At the same time Smith has treated me well in all cases.

So if it is a comparison of Ruger vs. Smith revolvers, I see no issue at the CS level.
