Carrying a G17 would be a PITA. Too big so it will just get in the way. You really want to lug a full size Glock 17, with your bow and gear, while dragging a dead deer out of the woods?
.40S&W is a better caliber for woods walking and hunting. Personally I have a G27 and a Walther PPS in .40 that I use when out in the woods. The G23 should do you just fine.
