The three you're considering vary quite a bit in weight. PPQ - 25 oz, P226 - 34 oz, SP-01 - 40 oz. Think about that before you buy. As far as where to get an SP-01, Guns & Ammo in Memphis TN (Summer Avenue) has one in stock. They aren't online but you might give them a call. You will love the SP-01 if you get it, I promise!
