Doesn't affect the criminals in the slightest of course.. Pre-firearms ban, prices were significantly cheaper.
no matter what kinda of "control" you put on firearms themselves, this quote from Telgriff, will always prove to be true. they are called criminals for a reason, they break the law. a minimum price will only serve to fuel the illegal gun market, IMHO. criminals will always have their ways of getting guns, be it through gun runners, b&e or whatever means necessary. a minimum price they will never have to deal with.
