I had a student bring a gun to the range recently that I had never seen or shot before, an EAA witness. It was a SA/DA semi-auto with a safety, but to my surprise, no de-cocking lever!
I had to teach him how to load and charge the gun then carefully lower the hammer by pulling the trigger. Needless to say I think this is a risky design, especially for beginners.
Couple that with the fact that it was a very large and heavy gun, but only chambered for 9mm and I was left thinking that there are so many better choices out there. It seemed reasonably well made and functioned and shot well though.
