I carry the 686 because:
I CAN carry it comfortably, in shoulder holster, while fishing in bibs.
I CAN re-set on target, for multiple shots,
There is no consensus on where to place that one shot on a charging Griz.
In your hiking buddy's knee.
I like the ruger Redhawks Alaskan in 454 for all the same reasons, except, center mass aim point with a handloaded, 410 grain wide flatness gas check at 1400 feet per sec. Should only need one shot. Alas, in Michigan we have black bear, no grizzly.
