I recently purchased a 9000s, one pf the mags has the snap grip plate which I really like, the other is the flat plate. I'm not fond of the flat plate. I've been searching for days now and can not find base plates for the mags.

Does anyone know if the base plates from the PX4 subcompact will fit the 9000s mags? Or does anyone know where I could find the correct plates? I would settle for the standard extended mags as well.

Thanks in advance for any thoughts, comments or leads!
