Type: Air Pistol. Manufacturer: Sig Sauer ASP Model: Sig Sauer ASP P320. Materials: Metal and plastic build. Weight: 1.81 pounds (821 Grams). Barrel: 4.75 inches - Rifled steel. Propulsion: 12 gram CO2. Action: Blowback single and double action. Ammunition Type: .177 caliber pellets and 4.5mm Steel BB's. Ammunition Capacity: 30 round belt fed stick magazine. Max FPS: 430 I was happy when Sig Sauer released their ASP Sig P250 and P226 CO2 Blowback Pellet Pistols with their 16 round double sided stick magazines like we have seen in several otters CO2 Pellet Pistols. But I love the introduction of the 30 round belt fed magazine. I am hoping the belt fed magazine performs while actually shooting pellets as good as it feels when dry firing it, I guess we will have to wait and see when I do my Field Test Shooting Video :) Overall the new Sig Sauer ASP P320 Pellet Pistol looks to be an upgrade of sure to the P250 in terms of improved weight and a higher capacity magazine.
