I am one of those who have actually used a gun to stop a threat. Both night time and day time. I can tell you this, aiming is rarely accomplished. Speed of draw was necessary, hip shooting is necessary and probably should be trained. At night you notice the flash, but the sound is non existent....Everything is in slow motion but happening at the speed of light and to understand that you have to be there. For the average CCW person, familarity with his weapon, practice taking it from its hiding spot, pointing at a target and dry firing are good techniques to practice.....beyond that, going to the range and killing paper targets is good.....A "Hogans Ally" training facility would be nice but suits law enforcement better than the average citizen....being prepared to shoot and shooting when necessary complete the picture. My humble opinion only....
