It is designed to get your heart rate up and maybe some adrenaline going which will give you a mild tunnel vision effect. Before you do a drill, with your firearm securely holstered, do 20 or more push ups. Go until you have a bit of a burn and you are getting out of breath. Jump up and do your drill as soon after as possible.  You will find that acute aiming is much more difficult, though general flash sight aiming shouldn't be too much different; this is why it is so important. This becomes a problem if your pistol is resting against something or the front of the gun is pressed into something soft. A simple drill to keep the bad guy off of your gun in a close quarter situation is to put your support arm straight in front of your chest bent at a 90-degree angle. This keeps the bad guy off you, while your firing arm is lowered near your hip. For practice: a tall target you can lean up against your arm and fire into it is good (make sure the target is soft, so the bullets don't ricochet and it doesn't splinter — make sure you shoot straight forward so you don't hit your arm). A couple times is all you need with this drill, just to give you the feel. Have a center-chest-sized target (10+ inches) setup 15–20 yards (13.7–18.3 m) away. Start your sprint at it, when you feel you are close enough to hit the target while moving, slow down to a crouched walk with your knees slightly bent (to keep your upper body smooth) and shoot the target.   Add different things while running: have a friend tell you when to start shooting (at random times). Or start running at the same time a friend starts reloading. Have the friend yell when he is done to let you know to start shooting. It can become a reloading vs. sprinting contest (it will also give you an idea of how long a reload feels like if you need to rush someone). If your location allows, stand 15–20 yards (13.7–18.3 m) away from your target. Have another person stand well off to the side pointing at a different target. The person standing to the side will have one round in the chamber and an empty magazine, with a loaded magazine in easy access (i.e. magazine pouch). You should have your gun out at and the ready. The other person will fire; you start running at your target. When you are close enough to get good hits, you shoot; if the other person is able to reload and fire at his target before you shoot, he wins. It is best (for safety reasons) for the other person to be aimed and shooting at a target which is different direction than yours, so at no time will one person be in front of someone else's muzzle. Additionally, you can try reloading while running at the target, then shoot the target when you are done (this is the most advanced version of this drill).

One-sentence summary -- This drill can be added prior to any other drill. Most semi-automatic pistols will not fire if the slide on the gun is not in battery (full-forward) position. Charging a bad guy seems like a stupid idea in most cases, but if the bad guy is reloading, or otherwise distracted, it can be of great benefit (you may be able to catch them by surprise or disarm them).


A good method when you're first sneaking out is to hit up the bathroom and use it as you normally would. Flush the toilet, run the water, and shuffle back and forth to the bathroom as if you were just doing your thing. Then make a break for it, slowly.  If someone hears something, they'll next hear your bathroom routine and drift slowly back to sleep. It's a familiar sound. Then they'll be comfortably sleeping by the time you're at the back door. Just don't overdo this step. If a parent heard the toilet flush and you walking back and forth every 5 seconds, they might come to check up on you. Take your shoes off and get your sneak on. In general, you'll want to move extremely slowly through your house, especially if you have to sneak past your parents for any reason, or deal with any excitable pets who'll make a big commotion. In general, leave the lights off. If you've got to negotiate a particularly cluttered room, or one with lots of edgy furniture, you might consider flipping it on for a second to get your bearings. As long as it isn't visible from your parents' room, you'll be fine. Get the layout, then shut them back off. For floorboards, pause as soon as you hear a significant squeak. They're hard to avoid, but a single squeak every thirty seconds won't rouse anyone.  As for the door, it's usually best to do more like ripping off a Band-Aid. Don't let it squeak eternally, open it only as far as needed to squeeze out and close it almost all the way. Turn it to pull back the lock and push it slowly and gently into place. Then release the handle. Continue being quiet as you walk around the outside, being especially wary of gravel.  If you're driving, you need to be extra cautious. Back your car out of the driveway in neutral and wait to start it until you're somewhere up or down the street. Leave your door open a crack until you get your car started. In the middle of the night, car sounds carry. The easiest way to get back in will be by leaving the door unlocked and slipping back in without having to use keys. If, by some chance, one of your parents gets up in the middle of the night to get a drink of water and checks the doors, you might find yourself locked out if you don't have a key. Leaving windows open can be somewhat sticky, as the noise is conspicuous. You might consider unlocking one as an emergency, if you don't have access to a key. Crawling in through a window without making any noise is a difficult proposition, though. It's very unlikely you will get caught sneaking out in the first place, however, sneaking IN is a whole different story. Use extreme caution when you're returning to your house, especially if you have a dog.  Survey the house before you enter. Are any lights on? Do people seem to be up? If the answer is yes, start getting an airtight alibi together, or booking a trip to Mexico. Slip back into your pajamas to give any possible alibis more credibility. If you try to say that you just went out for a walk, it'll be more believable. If you make it as far as the kitchen before your dad comes bounding in demanding to know what you're doing, it's probably best to take your loss and give it up. Make an easy excuse, like: "Just getting water. I'm tired. Goodnight." It might be tempting to try to out-wait him, but you're asking for more trouble that way. Save it for another night.

Try the bathroom fake-out. Step lightly and be as quiet as possible. Be extra cautious around squeaky floorboards and doors. Leave the door unlocked and take an extra key. Have your fun and then sneak back in. If you arouse suspicion, give it up.
