Does dry firing a semi auto in DA improve SA trigger as well?

Dry firing isn't the way to improve the trigger pull. It's a good training technique for sight picture and trigger control, though. Have a ttrigger job done by a smithy.
 
I think he is refering to breaking in the gun. Not related to dry firing practice in sight alignment & trigger control

This helped on my CZ85C. I think it tends to polish & burnish where the hammer & sear interface. That said, this is not a cure all for heavy & rough triggers. If it is really bad I suggest you follow Sunrays advice & get a good gunsmith to fix the problem.

Please do not practice this on rimfire guns, you could damage the chamber & or the firing pin.

Ok, nevermind. I kind of answered my own question.

My new sig had an ok trigger. SA had a bit of creep and DA was kind of gritty. I dry fired about 600 times. I had to stop after a while b/c my fingers would get tired with the 10lb trigger pull.

I came up with a great idea though. I saw a sharpie on my desk, and took one end in my left had, put it through the trigger guard and rested the other end on my desk. Then I moved the gun up and down to pull the trigger. After about a half hour I counted just over 4000 trigger pulls. The trigger was now sqeaky so I oiled up the moving parts and tested it out.

SA was very clean and broke like glass no matter how slow and gentle I pulled the trigger. DA was still heavy, but was now very smooth, much better than before.

All you did was naturally polish the sear , and ease the spring tension - You can speed up the process with a little bit of polishing compound (not valve grinding paste) but plastic polishing compound like the Tamiya stuff for models or maybe dvd cleaning paste - Memorex Optifix or similar
