Clean it and the mags and go shoot it. I bet you will be pleasantly surprised at how it handles.
The 40P is the only gun I recommend a steel guide rod since it has the buffer (make sure it has the plastic buffer installed around the recoil spring).
The frame is a standard 75 design and has all the same internals as any decocker CZ (non Omega). The firing pin is a standard CZ design too so any of the CZ extended firing pins can be installed.
I run a heavier Wolf 20lb recoil spring and it still sends the brass flying.
Cheers,
