I carry my 454 as a hunting weapon and a self defense tool. I am so damn close to 60, I can rub up against it, thus my eyes aren't what they used to be. These days, I need the scope for a humane 15 yard kill. I always figured that if an attack comes, it will be quick and close. My revolver is in a cross draw holster and sits loose in it. If I do get it out, I could hope to get to aim, but as fast as these animals are, I figure it will probably be a one shot deal before it goes to claws and steel. (Yeah, like I have a chance)
I have trained for thirty years on the point and shoot method. It's not as inaccurate as most people think if it is done correctly.
As an aside, During our yearly Jr. Rendezvous, I tell the kids the story of Hugh Glass.
