No problem Carlos.
They are actually pretty close in size. The CZ is 1/10" thinner if you don't include the slide stop and safety. If you include all the levers on both, the CZ is slightly wider than the Glock but still less than 1/4" difference in width... excluding grips. The CZ grips are just over 1/4" thicker than the G19 at it's widest point.
The CZ measures 5.20" in height as opposed to the G19 at 5.00, both being measured from tip of rear sight to lowest point of mag. (ten rounder with plastic floor plate in 75) Again, less than 1/4" difference.
I ligned them up side by side with the barrell tips against a straight line for length comparison (see pic below). The longest point on the G19 is the bottom of the grip just below the lanyard hole. The 75's longest point with the barrell squared against a flat surface appears to be the grip tang at the top of the grip frame. The G19 appears to be just a tad longer using these points. Yet again, less than 1/4".
Pic for comparison...

Capacity is 13 rounds with a CZ high cap and 15 rounds with a Glock high cap. The CZ is noticeably heavier but I have no way of measuring the difference in ounces. Shootability is subjective and since I have put far more rounds through Glocks I feel more comfortable shooting the G19 at this point. Reliability has been absolute with both to this point, but again, I haven't put as many rounds through the 75 as I have the 19. As for accuracy, they are both more accurate than I am most days!
Hope this helps...
