I have the CZ 75 B sa bug aswell, Pretty sure its going to be the 40cal. With a price point of less than $600, I cant see how that could be beat. She comes stock with the flat trigger that most S/A shooters enjoy, So when ya figure the upgrades a person may want to see on that beast, A S/A comp hammer is said to improve felt trigger pull as well as look real cool. Then a CZ FAO elevation adj. rear sight, A fiber-optic front site to meet your fancy. Should throw a 13lb main spring in there and maybe down the road some new grips would be nice. All tallied up the extras are under $300 bucks. Say under $900 dollars and you have a sweet pistola In my book.
