I have been looking around the internet at the .40S&W Sig P250 Compact in two-tone finish. I am seeing some really large variations in pricing on the gun. Some places have it as low as $399 and some as high as $529. I ordered one at Brightwater the other day and they wanted the higher end of these numbers. Even Bud's website has some of the guns at a low price and other ones at the higher price. Does anyone know why the prices are varying so wildly on this gun?
