There are a lot here I have used, and a lot more that I've never seen before, but really like.
A few of my favorites
"Its hard to argue with a half ouce of copper coated lead traveling at 600 miles an hour" - Me (230grain jhp at about 880fps)
"You never want to be the one who brought a knife to a gunfight, and you never know if its going to be a knife fight or a gun fight. The best solution to this problem is to always bring a gun. That way the other guy may well be the one to bring a knife to the gunfight"
and a few general gun safety ones.
"The two loudest sounds in the world are a click when you expect a bang, and a bang when you expect a click"
(when teaching gun safety to a few friends before we left to go shooting clays)"Ok guys, its fine to have a little fun, but its time to get serious now and listen to the guy holding the gun"
