Don't buy a Kel-Tec.
Think about the other things you need to do with that money.
Think about the fact that eternity is only a heartbeat away and how you're going to explain your "need" to buy a Kel-Tec pistol to the man on the great white throne as opposed to the many other things you could have done with that money. Remember the closing scenes in Schindler's List where he realizes what the proceeds from his car might have meant. The choice confronting you is no less stark.
And before someone accuses me of being a left-wing liberal, I am not saying that buying a gun is wrong. I have no problem ensuring that every member of my family has the means to defend themselves as a "need". What I am saying is that once you have the guns and appurtenances you "need", you must then think about the effect of satisifying your "wants".
