The (square) CL is the standard Italian date code, not a proof mark.
That is a new gun, CL is this year, 2014.
My source website on the subject of "Italian proof marks" indicated it was the proofing mark, which did indicate a year. However, I haven't been able to explain the M in the CM. It is not CL on the gun, but indeed CM. My source table ended at 2011. What source did you find?
