Conventional wisdom would have us believe that they are not effective. The Dec issue of American Hunter there is a brief blurb about two separate Grizzly attacks that both took place in Yellowstone on 6 October.
Both attacks were successfully thwarted by handgun carrying bowhunters.
One Grizzly was scared away by a hunter who fired a ".45 caliber pistol" after it had it had "tossed about" a second hunter who played dead.
The other Grizzly was "doused with bear spray" which deterred it only briefly giving the bear spray wielder's buddy time to draw his ".44 caliber handgun" and dispatch the bear with two shots when it charged a second time. The dead Grizzly is thought to have been involved in another attack in September on another bowhunter.
In spite of this, I fully expect to hear the same platitudes about handguns and bears the next time the question is asked on TFL.
