I have been out of pocket for a few months, and would like some feedback on pricing. At the local gun shows in Dallas less than a year ago, prices for base non-nightsight guns 17, 19, 22, 23, 31, 32, etc, were $439, with typically higher prices for porting, night sights and other upgrades. Prior to Christmas of 2009, those same prices at the same shows jumped to over $500, but at the last show those same comparable guns were $445 (plus tax). Any market forces that caused that swing? Political, financial, Euro vs/US$?
