I have a bunch of S&W revolvers and a bunch of other pistols, but never had a S&W auto. I've looked at a few, model 39, 59, and some modern stainless ones, but none really stood out. OK the nickel 39s are pretty cool. Anyway I found this 469 and thought it was neat. I don't know much about it/them, but supposedly this one is unfired. I can't find the TBU serial number in the catalog but I'm guessing it's from the mid 80s. Anything I should know before I take it to the range?
