RWB Drum Magazine Features Black polymer construction keeps the drum lightweight relative to its capacity while resisting the wear that comes from repeated loading and unloading at the range. As new production rather than surplus the magazine avoids the wear corrosion or feeding inconsistencies that can plague older military surplus drums giving shooters a more predictable feeding experience straight out of the box. The 40-round capacity gives a Glock .45 ACP pistol dramatically more rounds on tap than a standard magazine reducing the frequency of reloads during extended range sessions or training drills. This makes the drum a practical choice for shooters who want to spend more time shooting and less time reloading between strings. Because RWB builds this magazine specifically for the Glock .45 ACP platform rather than as a universal fit shooters benefit from a magazine engineered for reliable feeding in the pistol it s designed to run in rather than a generic adapter-based solution. The drum s grey polymer body and mechanism are built to withstand the stress of a spring-driven feeding system cycling a high round count repeatedly. For shooters who want to reduce reload frequency without switching to a different firearm platform the RWB Drum Magazine is available for sale at GrabAGun as a straightforward capacity upgrade for Glock .45 ACP owners.
