Dee, Bob Riebe, All I can sat at this point is "What ever trips your trigger."
For me, based on my experience where I had, in some cases, as many as several hundred "dangerous animals" attacking me at one time, all armed, intending to take my life, or leave me wounded, I stand by my position on the laser sights, as the combat troops in Iraq do. During my two tours in Viet Nam, laser sight were unheard of, but had they been available, knowing what I do today, my weapon would have been equipped with them.
If you go back and read my post, I never said replace the gun's sights with a laser, but as a supplemental sighting system they can't be beat. I still prefer a good set of white outlined night sights on my gun, and the opportunity to choose the site according to the situation.
As for protection from a "charging dangerous animal," what is the probability of this occurring, and how often are you exposed to such a situation? Over a sixty year period, I have hunted almost everything in North American, with the exception of Musk Ox and Polar Bear, and never been in a situation where I was attacked. I had several close calls with pigs, one with a Polar Bear in Greenland, but was never injured by one. In my opinion, the thought of being attack by a dangerous animal (other that man) is so remote that there is really no cause to be alarmed. It does happen, but most often when it does, the individual has put themselves in a situation to cause it. In most cases a "dangerous animal" will retreat as quickly as you do, given the opportunity.
