I've got a little 3-inch 65-5 that's the apple of my eye. I've owned and shot hundreds of Smiths, and done trigger jobs on several dozen, but this one is my best yet. Shooting anything else after getting used to this one is a real eye-opener. I personally think the three-inch barrel is the perfect length for an "all-around" gun, it carries well, shoots soda cans at 50 yards like a target gun, and it looks and feels great. If you're into blued guns, the 13 is a great choice, I just happen to love stainless.
