The point MB makes about practice and your skills defaulting to your level of practice in a crisis can't be overstated. I recently took my first tactical pistol course and it was eye-opening to say the least. I am not new to guns and pride myself on my competence and safety. But...I found out real quick that anyone with an inclination to defend themselves with a gun needs instruction and practice. When we do things at the range, everything works fine, we change mags like rock stars, we shoot tiny groups and think everything is rosy. Try that when an instructor is shouting a target sequence and has filled half your mags with snap-caps and 15 people are watching you and you are being timed. Point is, when we are at the range or sitting on our couch thinking about self-defense, we are in control of the situation. In a crisis we are not initially in control, we are trying to gain control of the situation. In my class I saw just how quickly "the wheels come off", but also how effectively you can train and learn deal with it. There is certainly some good info on the internet and forums, but I didn't realize until I took the course just how much you gain from legit, hands-on instruction. The tuition and ammo cost is peanuts compared to what you learn. My wife is taking a course in a couple of weeks and I will definitely be getting further instruction. (Tactical, practical, defensive firearms training. Not just ccw class). I urge everyone to do the same.
