I'd recomend a S&W Governor. I own ALOT of handguns and I love the versatility of the Governor in and out of the woods.
Mine is a tack driver with 45lc(even by full size hunting revolver standards). It's light and gives you the option to shoot 000buck, 45acp or 4 shot for easily killing small game for survival situations. I have put down some big hogs on the farm with a Federal 000buck in the back of the head. Devastating. The 45LC isn't nearly as violent as a 44mag to shoot but still uses a big heavy bullet with good penetration. I find it a good compromise between, weight, versatility, follow up shots, and accuracy.
A little review I did....
I've carried it all day in the woods and forgot I was wearing it.
