I have racked my brain trying to think of firearm regulations I believe would actually work. I am not talking about tougher consequences for illegal actions, but bans or restrictions that might slow down the flow of illegal guns.
The problem with a floor on gun prices is that it would increase, rather than decrease, the flow of illegal
guns. Pick a number - $250, $500, $1,000 - as a floor price and it will limit legal sales of new guns percieved as not being worth that amount. But there are plenty of Lorcins, Ravens, and other inexpensive guns already in the marketplace that will simply be sold illegally. Even without the existing supply of inexpensive guns, there are plenty of cheap guns around the world that could, and would, be illegally imported to meet the demand.
