Like some other S&Ws, when the 58s (and 57s) were in production, they were far from popular. I don't know about the stainless guns but would guess they weren't big sellers either.

I recall putting a friend's 57 with accessories on my gun show table thirty or so years ago. I don't know if anyone even looked at it over the course of a weekend.

I haven't checked to see how many .41s were made, but sounds like these would be good guns to hang onto nowadays.
