The 686 is an great revolver, well respected by all S&W aficionados, and the -5 Mountain Gun is one of the best of the best.
Next you'll have to look for a M625 MG in .45 Colt. Then you'll have a trifecta.
When you do post pics of you M686 please post one of the end label. My hobby's a little less expensive. I like to collect the info on the labels. I've got about 1,000 and so far I've spent $0.
