The P-01 is a compact, and the SP-01 is a full-size gun. They have the same dovetails, but you might find that sight heights for the front sights change slightly between the two models.
(I've used CZ full-size gun sights on a CZ compact without problem, but most sight makers make separate sights for the compacts, so they seem to think there's something different.)
You can also do what a number of us do -- recolor the factory white dots with flourescent model paint. That makes them MUCH more visible. You can make them larger, in the process, if you want.
