I have used CZC Cajun and CJ Maven on some of my CZ's and clones
All 3 do excellent work.
CZC does great work, gun runs great the cost a bunch but are worth it , long wait
Cajun does great work has good Customer service once you make to the top of their list and buddy does your gun shoot nice when you get it back. As a bonus you get to say you are in the Cajunized gun club
CJ Mavens has the best lead time, has superb customer service and can make a good gun great for a real fair price. He is a nice guy. you will be happy and you will be shooting your gun about 2 months sooner then with the other 2 guys. I suggest giving CJ a try. CJ Mavens does great work and you probably get your gun back in 10 days.
you will love your trigger when he sends it back
