I've got another shooting drill for you... It's called Switch Hitting shooting drille.because you need to... yep, switch the pistol from hand to hand. This drill works on several things:
First, You need to learn how to pass a loaded firearm from one hand to the other without fumbling with it. Easier said than done. However, with just a few runs of this drill, you brain picks up the ease of this technique, which in turn will make you safer when you brain is in "Fight or Flight."
Second, most of us do not shoot one-handed enough. This drill makes you do just that, while also automatically making you train more with the hand that you suck more with. No picking to just shoot with your "good side."
Boring? Yes. Looks easy? Yes. Harder than it looks? Definitely. Great Training? You be the judge.
