Joistman,
I have the SP-01 and the standard CZ-75. There is little real difference between the 2. The SP has a longer beavertail, the picatinny rail, re-curved trigger, and full length dust cover out front. If you ever think you might add a tactical light or lazer, then you would have the get the SP.
Otherwise, the 75 is an excellent pistol. If you want to shoot any which way you want to, I can tell you from first hand experience, a CZ is hard to beat (I've had a bunch of 9mm's through the years). My SP, with it's pet hand loads, can deliver 1.100" rested groups from 25 yards. That's impressive for a "service" grade pistol. The SP mag holds 19 rounds, and with one up the spout, that's 20 rounds.
Quite a few custom items are now available and can make a significant difference in how your CZ handles and feels.
