Magwell for Gen 4 G20-G21

SKU:GL-MW-20-G4
USE A 2mm Wrench to secure screw

Due to the G20/40 frame variances year to year it is recommended to use the SLR Glock 10mm Floor plate (Link Below)

Some frames will not allow easy mag retention in frame when using magwell. Frame to frame this can vary.

Our Glock 10mm Floor plates solve this issue.
