Smith 329 would seem ideal for your intended purpose. Unless you want/need more than 6 rds.
That's what I carry most of the time backpacking. It's not fun to shoot .. but I don't go backpacking into wilderness areas to plink. If I shoot something, it's to kill it. The 329PD teaches you to make the first shot count .. if only so you don't have to shoot it again. Not joking, not exaggerating. Surprising how accurate it is though.
