Auction fever is the likely culprit for the overpriced auction results. Or the seller is shill bidding to drive the price up.
What is amazing is the number of people who seem to want the weapon. Just like the S&W airweights over the last 2 years. S&W sold a ton of them and you can now buy "used" ones (with few rounds through them) for cheap, cheap, cheap. Why? Because .357 in a sub 12 oz gun is hard to control and stupid gun buyers who believe the "lighter is better & easier to conceal" theory bought one, test fired it with half-a-box of ammo, and now want to get rid of the thing and get some of their money back because they can't hit the target with it (or it kills their hand from recoil).
2 years from now, the LCP will be filling the dealer's consignment cases. Just like the Airweights are doing now.
