Glock 20 has become to go-to pistol for bear defense in Alaska. The only debate now is ammo...Buffalo Bore 220 gr or Xtreme Penetrator 140 gr. As the article pointed out, one of the cases was the only known successful reloading of a handgun during a bear attack, and they were firing semi-autos. Forget about reloading if you have some ancient relic wheel gun that only holds five or six rounds.
Kind of funny... but I remembered that Thomas Jefferson's matched flintlock pistols were state of the art... at the time he owned them...
