Welcome to the forum from the great state of West Virginia. That's a nice looking 686 that you have there. The problem with Smith and Wessons is that they are addictive. You seem to be displaying some of the common symptoms already. You just picked up your first one and already you want another. Trust me, as soon as you get that one you will want another. The good news is, that as long as you are careful, you will never lose money. I don't think that I own a smith that I couldn't sell for more than I paid for it. Mostly, they are as good an investment as gold, and a lot more fun!!
Personally, I like the older models before the "internal lock" was added, and "MIM" hammers, triggers and other parts replaced the older forged steel parts. This is mostly a matter of esthetics, as I have no personal knowledge that those parts are not as good as the older ones. Anyway, yours does not have the lock, and has the forged hammer and trigger. By the way, these parts are carbon steel, not stainless, and are chrome plated.
You have a beautiful gun there, and many feel that the 686 is one of the most practical guns that you can own: not to bulky or heavy, and yet sufficiently powerful for most purposes. Great find.
