Hiya Czechbikr and thanks for your thread. And I shall apologize early for digressions,and tangents. If you browse the old posts on your platform you will find many do it yourselfers and the great advice they share with each other. Altho I'm impressed with the technical knowlege they display,I'm more comfortable with just knowing how to do a proper field strip,clean and lube,and leave other issues,breakages,projects to Stu ,Rob,and Angus over at CZC as they are just down the street. But to entertain your question I'd like to offer some possibilities. Consider a toll free call to cz-usa and ask the service person to speak to a gunsmith,if that is a dead end, just their websites on line form to ask the question as you did here. I would think that any certified cz armorer had to begin with one course, and then the next etc.I imagine that not every person that wants to take such a course for the 75 is military or law, so they might could offer practical solution. One business called teaming network offers courses and looks like you would be looking at a one day course and 300-400 investment to pass a class on the 75. Perhaps another option is to see about shopping for a smith already certified and work out a deal. Even a possibility a forum member here has the equivalent of said certif. and might be interested in a pupil for a day or two.
At least now ya have an idea of a reasonable value for the lesson. It was several you tube vids that I picked and chose from to put together my own gun cleaning habit.And imagine maybe several of those are floating around for the work you are considering undertaking. And I hear that you are interested in learning,thats a proper starting point. I'm the guy that would forget to put on my goggles and be visiting urgent care, or looking in my shag carpeting for a pin or screw for a week,before giving up. Another concern I'd have is my safety, I'd worry an adj might still function,but my adj done incorrectly causing another issue,or worse. I'd wonder what role not being certified to work on said platform might affect my warrenty,and hate a scenario where I expected cz-usa to fix my FUBAR. Thats my best effort to entertain your question and hope it helped more than hurt. Be well.
