I am going outside of the box on your request for information. What I am going to say is based on actual experience with cougars, wild hogs, and black bear....use a 44Mag. Ruger makes a great revolver as does S&W as does Colt and others. If you do not like revolvers then get a Desert Eagle in 44Mag. The handgun is only for "oh shit" moments to get to your slug loaded shotgun or large caliber rifle. Be cautious these critters view us as food......creamy and smooth on the outside with a crunchy interior. Hunted and killed all of them with handguns and rifles.
