Looking to buy my son the Springfield XDS .45. While shopping around prices, I went to Springfield's web site just to do a little fact checking. On the spec page was a purchase now tab. This link takes me to the Gallery of Guns site, and then uses Gun Genie to find places in my area that use this service. Turns out that I can get this gun for around $40 cheaper at one place than what I've seen or been quoted at the places I have checked. Anyone have any experience with these services, good or bad?
