100% agree BigLew.
Another thing to think about....and I mean REALLY think about it... Is how are you going to react when and of you have to use the firearm? Are you really prepared to shoot someone else, even if it's self defense? If you're going to shoot someone, are you aiming for the knee, or critical mass? In my humble opinion, if you're not prepared to shoot for critcal mass, without hesitation, then, you better not pull it out, and it might be better if you didn't even have it.
I've never had to pull a gun on someone. I hope and pray I never have to. But, I have given it serious thought to how I'll react. Be prepared. It's not a game nor a toy.
