Well, I have comments for both sides of the argument here.

First, 20,000 dollars is a ridiculous price for a pistol. You'd pay half that for an Arctic Warfare Super Magnum Sniper Rifle for instance, and those things have an effective range of over a mile. It'd have to be one impressive pistol to match that.
On the other hand, the argument that gun owners are a responsible bunch is too broad a statement for me to accept until I see figures for the number of lives saved by a gun in America stacked up against those lawlessly taken by a gun.
On the other hand:
"I'm sure you (or someone *like* you) COULD do all sorts of incredibly evil things too. Do you have access to a baseball bat?"
So why don't gun owners keep baseball bats instead? And no, I don't consider that (my afore mentioned point, not yours) as stupid as it initially seems.
