I usually carry a Glock 19 with a G17 Mag or two in reserve.
That way if I lose it (haven't lost one yet, but) I can replace it quickly.
Also in a Hill People Gear chest pack, but I carry mine in the back compartment.
If I'm in coyote country (the four legged kind) taking the dogs for a 5 mile or so hike, a PMR30 or a SIG322 (when I get it).
