All I know of recent Defense of Life & Property shootings is this one:
http://www.adn.com/news/alaska/story/897940.html
but the story does not say what kind of gun it was, other than "Ruger .454 Casull revolver". Ruger makes the Super Redhawk in 2.5", 7.5" and 9.5" and I know of at least one gunsmith customizing the SRH to about 5", and a few people have made other barrel lengths and even fitted SRH .454 cyinders into Redhawks. I am not at all sure Blackhawks have not been converted to .454 Casull.
Does anyone know what specific configuration the gun was?
EDIT: I found a more extensive posting (where this shooting was referenced in an earlier thread, ("Very Lucky to Be Alive!"......Thanx to his Ruger) thread # 62699, with pictures that show the gun. It is definitely a very short barrel, thus very probably an Alaskan.
Now, reasons for my vote:
I know of one guy who was involved in a DLP shooting when surprized by a sow with two cubs and there is no doubt that the short barrel made the difference. The first and only shot was straight down through the top of the bear's skull and was immediate upon clearing leather.
I know I am faster with a double-action revolver than single action in point shooting, especially one-handed. I suspect strongly that, unless the killing shot was the first one, that this was a double action revolver and that the action type did save this guy a mauling. Though, being a guide (and therefore, presumably more invested in training), he may be more well-practised than most.
My vote is the DA made a difference to the outcome.
