Caliber for the woods!
Here in rural Missouri in the woods you could encounter feral dogs, feral hogs, and very rarely cougars. Nothing much bigger than those critter roam these parts. I hear how 9mm is better than it used to be with modern HP's. I also recently had a run it with a dog which had been abandoned and became very aggressive. I now understand when people say dogs have a very thick skull which bullets just slide off of. Suffice to say I have lost a little confidence in my favorite Glock 22 (with Gold Dot 165 grain) for woods walking. I really want to carry my Glock 19 since its a little more light weight and its the handgun I shoot the most accurately. I have a Glock 23, but with all the practice in the world I can't get the accuracy out of it I want.
I am also looking for an excuse to buy a Glock 21 or 30 for my big 'ol farm hands. Now I am leaning towards a Glock 30 since you speak highly of it.
If you were to come for a hike or to go fishing at the river with me, and you were limited to a Glock, what would you bring?
