Sig Sauer introduces another in their line of the Advanced Sport Pellet Air Pistols, the new P320 Air Pistol. This semi-automatic .177 caliber ASP pistol is the first air pistol in the world to feature a 30-round belt magazine and is designed to look and feel like the highly-acclaimed SIG SAUER P320 centerfire pistol. The P320 ASP air pistol features a metal slide with realistic blowback action and polymer frame in addition to a smooth slide safety. The air pistol also features a double-action, has a front blade sight, fixed rear sight and an accessory rail. Powered by a 12 gram C02 cartridge, you can expect velocities up to 450 fps but this may vary depending on pellet weight, temperature and altitude.
