thats the militarys answer, toss enought ammo around your bound to hit something. =) I dont like the 9mm personaly and i try to get myself to buy one just to to CC with. But then i look at the 45 -v- the 9mm when its time to carry and i always grab the 45. I like to KNOW your not coming after one shot. Then 9mm is great if you wanna blast 4-5+ rounds at someone to stop them. But i take the 45.
