I really like what Sig Sauer is doing for airgun community. What I mean by this is that rather than simply slapping their License on an already existing airgun like many other companies tend to do, Sig instead has decided to create something new and fresh. Sig Sauer has in brought new advancements and deigns to their APS Airgun line that nobody els so far has been able to do and with each new ASP Airgun Sig Sauer has improved upon their designs always staving to be better than the previous version. That’s exactly what the Sig Sauer M17 ASP CO2 Blowback Pellet Pistol is to me, Sigs best ASP Air Pistol to date!
