What I really like about the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol is that like all the other APS airguns from Sig, it is a product that Sig has decided to invest a lot of their time and effort to develop rather then simply grab an existing arigun product from a manufacturer and slap their license on it. Sigs product ingenuity is what will help to improve the airgun industry overall. Getting back to the Sig Sauer ASP P226 CO2 Blowback .177 Caliber Pellet Pistol, it's a really solid CO2 Pellet pistol that is a lot of fun to shoot and for Sig Sauer P226 owners, the pellet shooting airgun version offers a super economical and safe way to get some practice in using a product that looks, feels and shoots similarly to their real steel counterpart.
