Handguns and Self-defense
Hell in a Handbasket has an interesting discussion going with Spoons in the comments to this post. He makes one point that deserves serious reflection.
In my handgun course I have the student take part in three lessons. 1,000 rounds are fired by the student over those three lessons, and it's only then that I figure that they have a reasonable chance to defend themselves when they're going through the worst few seconds of their lives. This is good enough if the student goes to the range at least once a month and fires 100 rounds to maintain the minimum level of skill.
