I would have to agree with some of the earlier. Dont worry about the little things. Go shoot more. Shot placement is always key. You could have the super duper mac daddy blue light bought after 10 pm on the harvest moon in October baddest a$$ hollow point on the planet in your home defense platform (notice I refuse to say weapon) and it really wont amount to spit if you dont hit your target. Just shoot have fun and God forbid the time ever come when you have to actually be in the situation where it is a matter of you or ?....Your life will be changed for ever.
