This VG2 Advanced Upgrade Kit allows you to convert a VG2 holster shell into the full Advanced VG2 holster. Please note that the VG2 holster shell is not included in the kit. Also note that the CLAW is only compatible with the pistol model of VG2 selected. For example a Glock VG2 CLAW will NOT fit the M&P VG2 holster shell. Also, the VG2 Advanced kit is not compatible with the Basic Kit Strut or the Lanyard option.
