I installed the 92050 Dawson Precision Fiber Optic Sight Set CZ P-07 P-09 tonight. For my interests, these are way more useful, although I still like the extra height of the suppressor-style heights quite a bit.
I also put on the largest backstrap to better fit my size XL hands. Both changes made me happier - stronger grip + sights I am familiar with a much faster with.
I re-measured with the trigger gauge - 7 lb 15 oz DA, 3 lb 6 oz SA, pretty consistent. Some quick dry fire was promising.
I need a window of time for some research on P-07 polishing, then another disassembly / polish and reassembly session. I think this is goign well enough to invest in an AIWB and maybe OWB holster.
