Well, I sold the 66-2 and got a 686-3. Nor unhappy in the deal at all. The 686 feels like it was made for my hand. I've been spensing time polishing it with Mother's Mag Polish and it sure is a looker. I thought I'd miss the 66, but I don't (at least not yet)> My reasoning was I don't know what I'm gonna be shooting in 10 years. I don't like being limited in what I shoot or how much of it I shoot. If it says ".357 Magnum" on the gun, it should be able to shoot .357 magnum if that's what I want to feed it.
