Many have suggested S&W revolvers and I can agree with that. If you look at the really old Smiths, the most valuable are the big ones, the Model 3 Americans and the Russians, and the .44 hand ejectors when you get into the 20th century. Therefore, my advice for the future is N-frame S&Ws of 1950s to 1970s vintage (some of later vintage are also OK, and these, by the way, are also fun to shoot). Colt Match Targets, Pythons and 1911 Gold Cups would also be good, but everything of course depends on what you can afford to spend. Therefore, I won't be passing on any first- or second-generation Colt SAAs.
