When I conduct CQB training with pistols, regardless of the platform, I always adhere to the following schools of thought:

1. You should always have two weapons and two holsters on your person.

2. You should always have one of your weapons with a very bright, mounted tactical light on the weak hand weapon. You must identify targets before releasing a round.

3. If you require to manipulate doors or breach objects, always holster your weak hand weapon. Use your weak hand to manipulate objects.

4. Your two holsters should be easily accessible with a minimum of one extra magazine each, no flaps.

5. The two weapons of your choice should both have the exact same ambidextrous controls and be the exact same model which utilize the exact same magazines and ammunition type. No exceptions.

6. At a minimum, your weak hand weapon should be mounted with a tactical light, but it is ideal to have both mounted with a light. It simply requires more training. You want to confuse your enemy, not yourself!

7. Both of your tactical handguns should be out of your holsters whenever possible, and ready for engagement.

8. Your strong hand weapon is what you aim and fire with, using the weak hand weapon (specifically the tactical light), for misdirection purposes. If you have two lights, you may reverse this depending upon your position. For example, no matter your set or position, the light should be as far away as possible to your actual center of mass position. If on knees, the light should be held as high and away from your actual center of mass as possible. (this is what the bad guys will be drawn to, aim for, and assume your center of mass is located when firing)

9. If fired upon and in a very weak defensive or offensive position, it is tactically sound to drop your light-locked on weapon light firearm after being fired upon, in the direction of your attacker, for the sake of misdirection. This will give you a clean shot in relative safety, away from where the bad guy will believe you have have been injured.

Misdirection is key in a situation at home and against multiple intruders Your only advantages will be this type of misdirection (example: moan loudly when dropping your lit-locked firearm to feign an injury while also making sure the light is directed straight down the hallway for which the attack is coming from) and your superior knowledge of your homes layout.

Much more, but good basics for anyone.
