Type: BB air pistol. Manufacturer: Cybergun. Model: Sig Sauer SP2022. Materials: Metal and polymer build. Weight: 1.7 pounds. Barrel: 4 inches, brass, non-rifled. Propulsion: CO2 x1. Action: Semi auto non-blowback, double action only. Ammunition Type: Steel BBs 4.5mm. Ammunition Capacity: 23 rounds FPS: 328 (Tested way higher!) I ordered my Cybergun Sig Sauer SP2022 Sig Pro with two other Cybergun pistols (The Jericho 941 and Sigarms GSR), all of them in the lower and more affordable price point, out of all three of them so far I am really liking the SP2022 for a lot of reasons: It just looks really good, it has good weight and feel, for an air pistol in this price range to have a metal slide and full metal drop out magazine is also a welcome change. But most of all mine shot so much harder then expected that I was almost afraid to publish my test results! Even if it shot closer to the claimed fps this gun is well worth it and I would still be very happy and quick to recommend the Cybergun Sig Sauer SP2022 Sig Pro.
