1. The magazines for the 2nd and 3rd gen will definately exchange on the PT140 and PT145.
2. The PT111 Millenium and the PT111 Millenium Pro do not interchane. Not sure about the PT111-10 vs PT111-12.
The reason for the PT111 standard pistol not being able to use PT111 Millenium Pro mags and vice versa is simple. The Millenium Pro guns are third generation guns and had frame, internal demension changes, and parts redesign. If the 12 round Mil/ Pro magazine fits into a Mil/ pro pistol, so will the 10 round Mil/pro magazine. However the 10 round standard PT111 mag for the standard PT111 will not fit Mil/pros. Have to clarify and verify this when ordering mags from a source.
