To me, the P01 will always be the aluminum framed decocker model you are describing. I'm not a fan of the times when CZ gets muddled in it's model names to cover an excess of parts one way or another. Just seems wrong to have called the 99041 steel framed safety equipped compact a P01. Realistically, this should be called the SP01 Compact, not P01. But, that's just me.
Having muddled the naming, we will now have to be more specific when describing a pistol. Can't just say that I'm selling a P01 (I'm not BTW) but will instead have to say that I'm selling my aluminum framed decocker P01 (No, I'm still not selling it).
