Recently Magpul came to market with the PMAG 17 GL9 17-round Glock 9mm handgun magazine featuring a new proprietary all-polymer construction for flawless reliability and durability for thousands of rounds. ZEV Technologies decided that the magazine wouldn?t feel complete without having an aggressively styled ZEV basepad. They immediately went to work designing the first basepad for the new magazine. After many drafting table conversations and rigorous testing they have come up with the definitive option for an extended capacity basepad. Factory parts come off Zev parts go on and then reassemble the unit using the same easily removable floor-plate that comes with the PMAG. Color variances in shades of black are a possibility and do not effect performance of the component.
