My local shop has a 686 that I've been looking at. It's in real nice shape and the price is decent. It has a 6 inch barrel installed and also has a 4 inch barrel with it. I think I'd be more comfortable with the 4. What kind of a job is it to change barrels? I didn't talk to their smith, but the salseman thought it would be best left to him.Haven't yet negociated the swap into the purchase if I decide to bring it home. Also what are you 686 owners opinion of this gun. It is a .357. Thanks
