I've decided it's time to purchase my very first wheel gun, and based on my research I've narrowed my selection to either the 686 or the GP100. I intend to use it primarily for shooting 38's as a range gun (not a carry weapon) or possibly for home defense with the 357 mag. Unfortunately, I don't have the luxury of trying them out side-by-side beforehand, so I thought I'd toss it out there for some input from the more experienced shooters. My lgs has the GP100 available in 3", 4", and 6" (I'm leaning toward the 4"), but the 686's are still hard to come by in this neck of the woods (even though the S&W factory is only a 20 minute drive from my house!). I realize the 686's are a bit more expensive than the Rugers, but I don't mind spending the extra $$ if it's a better value. Thanks in advance for your help!
