-P-01 14 rounds of 9mm, the P-06 (40S&W) holds 10
-CZ 75 compact can be had with either decocker or manual safety
Functionally, the CZ 75 (compact) BD and the P-01 are pretty much the same (size, mechanisms, slide). Cosmetically, the 75 BD frame is a little shorter and exposes the bottom part of the slide a bit when the slide is forward, where as on the P-01 the slide bottom is covered by the frame entirely, and as you mentioned the P-01's frame is aluminum. I'd be happy with either but I think the P-01's frame is a little sharper looking so I went with it.
