Hello,
I had a problem resizing 9mm Glock shot brass to fit my Kimber Custom II chamber. I solved it by running the ammo through the Lee Bulge BUster using a Makarov die. You can read a discussion of this here:

I solved my problem so I canuse my reloads in any 9mm I choose without fear of failure.
That being said, the PM9 is on my wish list.
