Here is a 10 shot group from the CZ-97B"E" with a red dot and another 10 shot group from my P-10C with open sights, 100 yards, from a wrist rest.  

I struggle with vision at 100 yards with open sights, so the P-10C group is larger than the 97B"E" group.  I got all the shots on the B-8C target with the 97, pretty close with the P-10C.  Atlanta Arms 185 and 115 JHP ammo.  I'm happy.

97BE and P-10C at 100 yards 7-21-17

The P-10C is excellent mechanically, just harder to aim consistently than the 97.
