I just recently did that very convrrsion on my SP01 Shadow.
Cz USA will not ship overseas. You will have to order from czcustom.com, choose the shape you prefer. I selected factory Custom SA trigger, it has pre and post travel adjustments.
I did not remove disconnector, as it does not engage if the SAO trigger is installed. Removing it is no harm either.
A competition hammer by czcustom or CGW will definitely enhance looks, and performance. If you plan to change hammer, also order pin no.9, as the one removed might not be reusable.
Then, you have to post some pics..
