Light, compact, rugged, accurate, dependable, effective backpocket/holster clipped-to-your-backpack weapon for snakes/trail obstacles. 50 rounds of hollowpoints fit in a shirt pocket. If you spend some time on the trail,your questions should be answered.
Hmm. Chainmail I am afraid I side with the original author, who said it was"small and light, but... a bit too small"
I tell ya what if I DID spend much time on a trail I'd want something a bit "larger" too. I like numbers like .44, .45 or even .50. Of course no one said those were "light" numbers, and you'd be hard-pressed to fit 50 rounds in a shirt pocket.
YMMV
... but it needs a longer barrel.
If we’re talking survival weapons, I’d rather not have something in aluminum.
A Taurus Tracker in stainless steel cost half as much, though would be much heavier, and a S&W 617 will give you 10 shots.
