I just got my new baby; a lightly used, well worn KWA M9 PTP, and I am infatuated.
Since I bought it used, I have the newer magazine with the metal baseplate and 2 little screws on that baseplate. I will be purchasing new magazines, but was fervently warned away from the "standard" magazines with the plastic bases.

I then saw these, and they say that they will fit in my M9.

If anyone has had problems with the crappy plastic ones, let me know.
If anyone has used the extended magazines, let me know.
If anyone wants to sell me M9 magazines, check the classified ads, and let me know.
Thank You.
