I'll just throw out the other side of the coin. I just sold some G20 mags I don't use at a pretty elevated price, but I did so not just to make a buck, but because there are some things I need/want to buy in case some legislation is passed, and I will be buying those at elevated prices.
Right now, I put the odds of Feinstein's bill passing at less than 50/50, but the odds of something passing at 50/50 or worse. The more time that passes and the more polls that are released that show most Americans don't support an AWB and even more Americans are opposed to a handgun ban, the less likely I think Congressman are to cave under the pressure of Sandy Hook.
However, anyone that doesn't think that stricter gun control of some kind isn't a VERY real possibility, simply have their heads buried in the sand.
