Would the magazines during the war be considered a disposable item? If so, the nubs wouldn't really be a weak point if they were designed to be used once and thrown away but I don't know what the soldiers did with the magazines. Is it known, did the soldiers keep their empty magazines or did they just throw them on the ground for the most part and get resupplied later? I have to say after seeing thousands of used magazines on various auction sites, the nubs always seem to be in fairly good shape.
