My husband and I both occasionally carry a 2 1/2 and 3" 686+, mostly for woods walks or when bears are sighted in the area. In a Sourdough Pancake and Galco Combat master. The stock grip on the 3" is good and a Hogue Bantam is a good alternate that's a bit smaller.
Grips L to R: Stock 3", Hogue Bantam, Stock 4"
