Well, I took the OP's meaning, based off John Taffin's writings, to mean a perfect packin' pistol for out in the woods. That said, I'd say it still depends on what woods we're talking about. The pine forests of the Carolinas are gonna be different than the scrub of Texas, and Idaho mountains are going to be different from both of them!
To me, for anything East of the Great Divide, a Glock 20 is ideal. With a 4.6" barrel, it's already more compact than a 1911 (length-wise, I'll grant you it's a lot thicker, and the heighths are about the same), but it carries 15 rounds of 10mm power (if loaded properly). And, the eastern parts of the US seem to have a bigger chance of bumping into someone in the woods who may be up to no good, like 'shiners, tweakers, or just plain badguys.
Now, if I were going up in the mountains out West, I'd leave my 10mms at home. And, while my ultimate, dream-gun is a custom 696, I have to consider what John Taffin (and the Orig. Poster) was talking about with emphasis on the word "PACKIN'." My thinking, in that case, is something that you pack along, but it's not your reason for being in the woods. You're out there camping, hiking, working -- whatever, but you're not there hunting or shooting as your main point of being there. In that case you want something powerful enough for the job, but light enough to stay out of the way. I have to go with John Taffin's choice for that type of pistol, which I believe was the 329 w/ CTC lasergrips. That pistol makes a whole lotta sense.
If'n a gun is anywhere near too heavy, it will eventually get left behind, and then it's doing you no good. That's why the Glock and a 329 are my two choices.
