I've owned both at one time or another. To me, the M2 felt bigger than it was (it seem especially wide in the pocket), while the PM2 seemed slimmer than it was. I don't really have a preference when it comes to the locks. Overall, I preferred the PM2, but, in the interest of full disclosure, I don't have either any more.
