Well, as for a 6"er I love my 686. I prefer the extra weight the full length under lug provides. I bought it used and the finish was great, the trigger job on it breaks like glass and I added a set of Kim Ahrends Maple Tactical Square butt Finger Groove grips. Shes a fine shooter. As far as versatility goes though, I love carrying my 4" GP100. Last but not least my 2.25" S&W 60-9 .357 is my beloved pocket gun for when ever/where ever CCW.
