I would be very surprised if The US would be giving the Italians carbines in 1944. The US invaded Sicily in July 1943 and Italy surrendered in Sept 1943. Italy was in complete chaos after the surrender. Most of the larger cities were left with no water, sewer or food by the Germans. The Germans wrecked the water systems on purpose to leave the US with one gigantic headache. If the Italian police were needed to help keep order, there were tons of Italian weapons available and plenty of ammunition and trained men to use it.
