My Taurus M66, thanks, with a supply of .38 wadcutter for small game and 158 magnum for big cats and such. It's 1" at 25 yards accurate with either. You don't list the number one gun to carry, a K frame .357 no matter who made it, if it's accurate with .38 and .357. That's MY choice. Light on the hip, powerful, accurate. It cannot be beat. I didn't vote, but if I had to, the mountain gun with a supply of specials for small game and magnums would be the choice from those you list. I like .38/.357, though, because I can carry a bit more ammo in the same space and it'll get the job done just fine. My 4" Taurus 66 is my go do back packing/outdoor gun now days, though I like my .45 Colt 4 5/8" stainless Blackhawk if there are to be BIG critters to encounter. The .357 is lighter, easier to tote, and carries more ammo, though, so I usually take it. The Blackhawk would be the obvious choice in Griz country, but I never go there. I actually bought it for back up when chasing hogs at night with dogs, something I haven't done in a while, either. It's an awesome gun, but breaks a little over 40 ounces on the hip and when you're hiking, every ounce counts.
If I had the money, I'd be lookin' for a used Taurus .41 mag titanium tracker (they dropped it) or a new .357 Mag titanium Tracker. I think that's the only way to improve my gun, make it lighter yet. No autos for me. Capacity means squat compared to accuracy when making a 75 or 100 yard shot on game or man. I can easily hit a man at 100 yards with my field carry guns. If I'm on my own, I really see no need for suppressive fire and you're going to have limited ammo on you at any rate. We're talkin' survival here, not war. Most autos would be next to worthless in this situation if they can't hold 1" groups at 25 yards, 4 MOA. I have one gun that can do that, a Ruger P90, and the .45 is just too wimpy and I doubt I could hold over enough with it at 100 yards to hit anything, never tried.
BTW, this is sorta a useless, but fun thread. Thanks.
