If I could only own 1 hand gun it would be the Glock 23....If you load up with the 180 grain GoldDots or the Golden Sabres you have a formidable round for ANY thing you would come accross in the woods, 4 legs or two. This is the only gun I carry in the woods....
The 23 is perfect for light weight and ease of carrying. Plus the .40 has every bit as much energy as a .357 without the recoil.
The FBI has determined that the .40 has more "One shot stops" on people than any other round for the last 10+ years. If it's good enough for that, its good enough for Black bears, cougars and wolves. I would want something a bit bigger if I were to venture into Grizzly country..... I would not hesitate to shoot a Grizz with a 10mm.
Plus in the Glock 23, when I carry it in the woods I have it loaded with a mag from a Glock 22 giving me 16 rounds before I have to reload, plus as the others have stated shot placement is paramount.
