Kingcobra, - Any good condition S&W 4" .357 is a good one. Personally my favorite is either a M27 or M28, both N frames and out of production but widely available. The M28 is the less fancy version of the M27. Both are blued finish carbon steel.

M 19/66(s) (M66 is the stainless version of the 19) K frames are really nice as well. The fixed sight K frames (M13 / 65 stainless) are also nice.

For simply a really good shooter, M586 / 686 (stainless) are also hard to beat. They aren't as collectible yet as the N or K frame revolvers, are extremely durable, and nicely bridge the size gap between the N frames and the smaller K frame guns.

You will not go wrong with any good condition S&W 4" 357 as a general purpose revolver. There a few warning caveats though. Once you buy the first one, you will want another one. Shooting .357s also makes you want to burn powder in S&W .44s and .45s. In severe cases, you also have to have .41s as well. If you are married, try to get your wife infected with this condition as well. That way when you feed the addiction, you can share it with her rather than POing her off so that she goes out and buys expensive shoes as payback.

Good luck. Pardon the humor.
