ProMag has done it again making a drum magazine that fits GLOCK 9mm pistol models 17, 19, 26, 34 and this drum also fits GLOCK magazine compatible 9mm AR-15 carbines.
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 9mm firepower and reliability.
This is not a factory GLOCK magazine. This magazine is manufactured by ProMag and fits GLOCK handguns.
