RWB Drum Magazine Features The RWB drum magazine holds 50 rounds of .40 SW dramatically extending the capacity of any compatible double stack Glock pistol beyond what a standard magazine offers. The polymer housing keeps the drum lightweight relative to its capacity making it manageable to carry and load. For range shooters who want fewer reloads during extended sessions this drum magazine cuts down on downtime between strings. Built specifically to fit double stack Glock .40 caliber pistols the drum drops in without modification to the host firearm. Its black finish matches most factory Glock finishes for a clean uniform appearance. For shooters who want extended capacity on the range without carrying multiple spare magazines the RWB Drum Magazine is available now for sale at GrabAGun.
