Interesting. The 1911 and the M9 both have safety levers. If they go with one without it, it will be the first time in modern history.
The CZ has a safety lever. I don’t know about any of the others.
But Beretta put their safety/decocking lever on the slide. A bad placement. Taurus fixed that, so like the 1911 the lever is on the frame ... and their copy is superior to the Beretta M9.
