Just got home with my CZ

It's very nice, I'm impressed with how smooth it is. For example, when you let the slide forward it slides smoothly into place, on my GLOCK 17 it slams into place so hard it makes my ears ring
Now to take it apart and clean it
A few questions:
1. Any way to make the mags drop free?
2. On the two rear sights, there is a dot of white in each little indentation, is there supposed to be on the front sight also? I think they may have forgotten to paint my front sight, no big deal though, I can fix that in 2 seconds with some paint. Plus I think I would want to make the front sight a different color for some contrast anyway.
3. Will dry firing damage the gun?
