Came accross a 200 pound black bear while I was walking my dog. Will my Glock 21 drop one? How much more penetration will a Glock 20 give my on a Bear? I decided to stick with the 21 for daily carry bit the 20 might be better for the woods? Do you think a Glock 20 would make a difference on a bear? THe largest thing I have is a 4 inch .357 mag... Guess I should of not sold my .480 Ruger... I need to get money together to buy a .500 smith.
