Take a level 1 tactical carbine class from Clint Smith at thunder ranch. I think you will find there is a world of difference between the "game" and training for the street.
And no I do not think you can get the full effect from some one who took the class once and is now ready to revile all. You will get your moneys worth.
Good Luck & Be Safe
First, with the most, WINS!
