Here's my criteria for "elegance":
1. Functional. Practical for its intended purpose.
2. Well-engineered and executed well in manufacture.
3. Esthetics. It's gotta be pretty.
4. When others see it, they wanta have one also!
5. Pristine. Gotta be in excellent or better shape.
For me, one of my Smiths stands out above all the others. It gets the Academy Award for Elegance for me. This is a Model 27-2, with a 3 1/2" barrel, blued, shipped in September, 1978. Target hammer and trigger, white outline rear sight, red ramp front, target stocks. I think it meets all of the above criteria.
You probably have a favorite for "most elegant Smith & Wesson" in your collection. What would it be?
