It all depends. For instance, Dave Sevigny is going to beat you with his Glock, regardless of what pistol you are using.
Anyways, the Shadow has few features that are making it easier to shoot, especially for the beginner:
* heavier frame with a rail, with more weight on the front help to recover from recoil faster
* a bit bigger beaver tail, comparing to 75b
*
no firing ping, comparing to SP01 Tactical, reducing trigger pull
* fiber optic front sight and thick competition rear sight,
* nicer and more comfortable trigger (though you have to watch for it, I saw Shadows with some old triggers installed at the factory)
