I too have never understood the whole -- I don't carry an expensive gun because the police will seize it as evidence if I ever have to use it argument.
What? Losing a $900, or $1000, or $2,500 gun is the least of my worries if I have to pull or fire a gun in self-defense. I don't mean to be condescending, but its almost moronic. The odds of you losing the gun by leaving it in a public toilet by accident is a hell of a lot higher.
If the gun has to give its life in defense of mine... so be it. I will eventually get it back unless something goes horribly wrong with my (legal) defense strategy...
