I let a lot of nice guns go when I was younger and have really regretted it, so I would really hesitate to let one go now. However, if it were absolutely necessary it would probably be my GLOCK G20 in 10mm.

A major source of objection to a free economy is precisely that it ... gives people what they want instead of what a particular group thinks they ought to want. Underlying most arguments against the free market is a lack of belief in freedom itself.
