dvanced Sport Pellet (ASP) brings to mind a small specialized operation devoted to performance, not unlike the local “speed” shops in many towns back in the muscle car era that helped the owners of Barracudas, Camaros, and GTOs go faster. Until recently it was the name of the air gun division of SIG Sauer. No more. When SIG committed itself to be a major player in this arena, and mapped out a strategic plan to get there, the manufacturer realized the division’s name didn’t reflect that commitment. So, it rebranded ASP as SIG Air.
