Springfield Armory XD MOD.2 45 series grip extension replaces the factory magazine base plate. They will add approximately 5/8" additional gripping surface while incorporating a similar texture to the factory grip. This extension will not alter the capacity of the magazine. *Note- This extension will fit the XDM 45, however the texture pattern across the front of the extension will not match the checkering pattern on this frame. This unit will NOT fit the single stack Springfield XDS 45.
