couldn't of said it betterI do carry a Springfield XD45. I have a CrossBreed SuperTuck for IWB, and a Serpa Sporster for OWB.
You're asking for a comparison between a .40 cal Glock and a .45 cal XD?
Other than that, the G22 gets my nod. It's has a longer barrel in the same overall length, is half a pound lighter, and has greater ammunition capacity.
