Spawned from engineering talks during the Magpul modeled Glock(R) magazine basepad development, we decided to round out the ZEV Technologies catalog of innovative products with an extended base pad for the standard capacity Glock magazine.Our 3-piece design is easy to reassemble onto the magazine, and can be easily disassembled for cleaning without losing any partsZev Technologies(C) will not ship any of these items to individuals living within the states of California, Oregon, or Washington.NOTE: GLOCK magazine not included. Not compatible with restricted capacity GLOCK magazines.
