Loaded in Nosler head-stamped brass with quality components throughout, ASP is built to perform across a wide variety of applications and engagement ranges, giving law enforcement professionals and civilians alike confidence that it will perform when needed. For 9mm and .40-caliber shooters who carry for duty or defense, this handgun ammunition from Nosler is built for exactly that.
