I have a skinny-barrelled Model 10 that was made, I believe, in late 1994. The 1994 S&W catalog was the last to show the standard-barrel as an option, the 95 catalog showing only the heavy barrel. Not sure when the heavy barrel was first offered, but I think I have one of the last new, skinny barrels that was offered. Bought it at Sports Authority, new, for just a little over two hundred dollars. It had been marked down several times and was languishing amidst the latest toys, including H&K and Sig autos, Glocks, etc., etc. I just had to rescue it from obscurity and oblivion. At the time I had them check their computers to see if they had any more in the system but mine was apparently the last one they had in any store. I wanted a second one. I also have an older heavy barrel but like the skinny the best. Seems to me to be an absolute classic, lightweight, graceful. Looks like a Humphrey Bogart movie. Will never get rid of it. Laz
