Two Cents is all your gonna get here. Practical training, notice I said practical not "Tactical"!!
Arms distance to 7yds I practice one getting off the "X", and point shooting from a modified crouch. At arms distance the last thing you want to do is go into a full twohand hold on your weapon(You just gave Mr. BG something to hold onto), and lost precious seconds getting shots off. Do this strong and weak handed. If your holster is properly postitioned you should be able toget to it with either hand(3:30 to 4:00 right handed, 8:30 to 8:00 left handed). At seven yards you can go to a twohanded hold aimed or point shooting(Remember to keep moving). Once you get back to 10 to 15yds sighted fire should be the norm, not saying point shooting can be done at those ranges, but it takes lots and lots of practice!!! Now from there practice at 25yds, standing, kneeling, or even prone. Use a baracade if possible, one it gives you a steady platform, second it gives you some cover from possible incoming fire.
Now if you've got the range find out where your gun hits at 50yds, those of us who've shot the old PPC course know what I'm talking about. You'll never be able to decide what type of encounter you'll be envolved in. Those of us who've had to practice the Tueller drill can tell you, it doesn't matter if Mr. BG has a knife, gun, or stick, from 21ft aka 7yds, he'll usually be on you before you break leather, thats the reason for getting off the "X", don't get caught with "Deer in the headlights look". If you've got a partner, get yourself a training gun, airsoft, watergun roughly the same as your carry gun, and practice this.
Next, dryfiring is your friend, use him every chance you get. Start slow, put a penny right behind the front sight, and practice squeezing the trigger(works best with revolvers, but can be done with semi-auto's) slowly till you can do it without the penny moving or falling off, and build up speed from there. Got a full length mirror, Please make sure your gun is unloaded, and practice your draw, from point shooting to aimed fire. When doing the point shooting look where the muzzle is pointing, it should be in straight alignment with your forearm pointing at the target. When doing aimed fire, practice looking under your weapon, or over, thats where the vital areas are. If you continue to point at your weapon, you'll probably hit Mr.BG's gun or hands.
