I purchased a cz75b from Angus Hobdell's CZCustom website. I had them install the single action trigger mechanism, fiber optic front, and competition rear sights, while I chose to add the competition hammer.
This gun shoots far better than I ever will! Despite a healthy 33 oz weight, I have no trouble carrying it OWB concealed. If you are a -10 lb vegetarian, it might be problematic, but as a Clydesdale (>200 lb) I have no problem.
