I am going to be purchasing a .357 (686) next month when I get back home from the holidays and I'm at a loss about what barrel length to buy first (yes I will end up with 4" and 6"). I currently have a 4" 629 which I love so I lean towards a 6" 686 for a little variety right now. Will be using this gun a lot as a sidearm during predator hunting (in the rotation of sidearms anyways) target shooting etc...not a defense weapon or a carry weapon.
