:cb2: The choice is between:
A) the Ruger SRH in .454, or
B) the S&W 629 in .44.
Since you like double actions, you like the strength of the Ruger, and a .44 will kill anything in North America that you are hunting, with a great variety of bullets, I'd go with Hclif's suggestion and get
C) the Ruger SRH in .44.
You've got the best of both worlds there. Strong double action, much cheaper ammo, and you can shoot a lot longer without wearing yourself out. The recoil will be about the same as you .45 Colt, so you already know what to expect, and you can get the long barrel you want. You can scope it later if you want to, but with eyes as young as yours, with the ability to see . . . I mean, hit a milk jug every time at 100 yards with a Vaquero, you probably have another 30 years before you need to worry about that!
If you are worried about bears in Alaska, you're probably better off with a pepper spray designed for bears
www.udap.com/ rather than a handgun anyway. Bear hunting, and a bear coming after you are two different situations. It is very difficult to hit a fast moving, charging bear in a spot that will actually drop him before it's on top of you. Sure, some people have done it, but they'll tell you--they were very lucky. (I believe our Founding Fathers refered to it as Divine Providence.) By the time you clear leather with a 9" barrel it might just be too late! (Hope you're tall with really long arms!)
