By coincidence just tonight I was looking at my SCSW & noticed that there was a 28-3. It had never occurred to me that there was such a thing but since they made them up to '86 it's only reasonable. I'm still quite a S&W n00b but I was kind of surprised that I had never even heard of one before, nor ever heard them being discussed. I've certainly never seen one in the wild and I spend a LOT of time at the used/consignment cases.
Are these things uber rare? Desirable?
I'll be keeping an eye on this to see what the experts have to say.
