I also went the Ruger GP100 route after shooting both, spent the $300 difference on ammo. The Ruger is more 'rugged', perhaps not as slim and refined, but actually weighs a couple ounces less (40 oz vs 42 oz according to their specs)....S&W has the reputation for the better trigger, maybe I'm not refined enough, but I didn't notice a lot of difference, the Ruger trigger seemed pretty nice to me. Whichever you choose, they are both great pistols, and a 686 is in my future plans as well, but I'm keeping my Ruger.
