S&W 686 4" is not perfect for everything but will get the job done in and out of the woods.
X2 I have owned two of those (80's Models) over the years and they have served me well. However I would not hesitate to take a look at a GP100 Ruger with a 4 inch barrel. I might be wrong, but I think the GP100 has a thicker top strap on it.
I have noticed some slight erosion (a groove) of the top strap above the cylinder, on the 686 that I currently have.
