No, I haven't seen any differance in gun prices.
A little off topic, but something I have noticed in casual conversation since the war started is the number of people you normally wouldn't consider as being the type to have firearms for personel protection - do in fact have such firearms. Not target guns, not plinking guns, not hunting guns - but actual honest to goodness guns for the sole purpose of personel protection.
I heard somewhere that a Japanies officer involved in planning the Pearl Harbor attack was asked after the war if there was ever a consideration to actually invade the American mainland. The answer was "of course not - too many private American citizens with guns". Somehow it's reassuring to think that "real people's" attitude towards the right to "keep and bear arms" hasn't changed much in 60 years - dispite what the PC crowd would have us believe.
