Umarex Magazine for Glock 17 Gen4 Features This Umarex magazine is purpose built for the Glock 17 Gen4 CO2 airsoft pistol matching the drop-free release and profile of the host platform. A 23-round capacity keeps shooters engaged longer between reloads useful for training repetitions or extended backyard sessions. The magazine houses a standard 12-gram CO2 cartridge which powers the pistol s blowback and firing cycle in a simple field-serviceable format. Its metal and polymer construction is built to withstand repeated loading seating and drop-free ejection cycles. Compatibility with the Glock 17 Gen4 CO2 pistol makes this magazine a practical addition for anyone running that platform for practice or casual plinking. Keeping a spare magazine or two on hand cuts down on reload downtime during range sessions or backyard drills. The drop-free design speeds up magazine changes letting shooters focus on fundamentals like grip and sight picture rather than fumbling with a stuck magazine. This magazine is available for sale at GrabAGun as an easy way to keep a Glock 17 Gen4 airsoft pistol running through longer training sessions.
