a good, lightweight .22. A tacsol buckmark/ruger or something more compact like a browning 1911-22 or ruger sr-22.....
This. For a few reasons.
A: Everyone needs a good 22 pistol.
B: Meat for the pot can be quietly taken with a 22 without alerting everyone and everything.
C: A 22 is great fun for casual plinking during a backpacking trip to pass the time.
D: A very shootable 22 capable of good field accuracy can be had in a very packable weight. The additional benefit is the weight of extra ammo; a lot of extra ammo can be carried for little weight penalty.
E: A lightweight 22 is easier to shoot than most comparable weight centerfire pistols or revolvers, which makes practice easier and more fun, which makes for a better shooter!
F: A 22 LR will handily take down any of the threats you mentioned. If defense against enraged AK toting methed-out Somali pirates or man eating tigers was an issue, perhaps your Glock 19 would be in order....but a 22 will work fine on random varmints.
Since you already own the Glock 19, the other guns mentioned won’t be of any real advantage, unless you’re simply looking to buy a new gun. Another option is a 22 LR upper for your Glock.
