The carbines have been used mostly during public order operations, as a form of display.
I don’t think they have ever been used (shot) much, but they were certainly in common use.
My first memories of the M1carbines go back to summer 1990, during the soccer world champs. I saw them used by the Carabinieri on the heads of really “turbulent” English fans in the “Lotto” underground station in Milan. As clubs...
They worked very well.
I just took off, not being interested in trying them out.
I was coming back from university, and got into that mess...
