Year after year, ProMag has increasingly become one of the leading manufacturers of firearms magazines in the world. Gun enthusiasts and law enforcement personnel have agreed, be it for recreational "plinking", competition shooting, or law enforcement, ProMag is the source you can count on. ProMag has done it again making a drum magazine that fits Glock .45 ACP pistol models and this drum also fits Glock magazine compatible 45 caliber AR-15 carbines. It features the same patented follower system as the ProMag 5.56mm AR-15 drums for ultra-reliable feeding. Over molded heat-treated carbon steel magazine upper housing combined with an impact resistant polymer drum housing and stainless-steel magazine spring for rugged use. Heavily field tested by ProMag's USPSA shooting team for use in Pistol caliber carbine competition this drum magazine sets a new standard for .45 ACP firepower and reliability.
