The Sp01 has a lot of improvements over the 75, including a better grip, ambi safety (left handed) and just a lot of small things that make it feel better. I'll still have the standard slide for carry, and doing it this way comes pretty close to what I'd pay for the factory custom long slide with the 75 frame (factory custom uses the guide rod, hammer, springs, about a $120).
