wow6599,
It sounds like the correct question is do YOU have real-world experience with both?
I own a CM9. My father owns a PM9. I have shot both pistols back-to-back on numerous occasions. I am well aware of the differences and similarities between the two models.
You seem to be a bit ignorant of the actual extent of the extent of the differences between the slide of the CM9 and PM9. While the CM9 has a more angular slide (especially at the front, which is still nicely beveled), there are no sharp edges anywhere on the slide except for the front edge of the ejection port opening and the slide serrations. The PM9 shares these same edges.
Therefore, I can stand my my initial comments.
