I love the Ruger revolvers, but I'm not very found of the barrel's underlug. I wish Ruger had taken the Security-Six, gave it a little more meat in the forcing come and then left it alone! I'm also a bit unhappy with the balance. The GP-100 is a fine gun, but it's a bit heavy for camping, hiking, hunting and fishing. For range shooting and home defense it's fine. Again, I love the Security-Six; also, the S&W 66. I have two 686s (an -0 version and a -6 Model (both 6-inch)), and several of the Security-Sixes, and the 6-inch models are wonderful. And though I also have some 4-inchers as well, I wish I'd picked up a stainless Service-Six.
For outdoors, I wish the manufacturers would ljust eave off the underlugs. Others may disagree. The one thing I love a about Rugers is that anyone can do action jobs on them. Just rent a couple of cowboy movies end dry fire the daylights out of them! I'd love Ruger to add removable underlugs. That way if you don't have guides to carry your guns in the wilderness, you would be able to lighten the weight.
The.357 magnum is a perfect outdoors gun. It can take all sorts of critters, including the two-legged variety. Back when the Security-Six was in production, I never once heard anyone complain of recoil or difficulty controlling it in the outdoors. The SP-101 is bit of a lightweight, and the Service-/Security-Six was just about right.
