Louisville Slugger MLB Prime Maple CG3-M110 Black Matte 34". Curtis Granderson took the M110, one of Louisville Slugger's top five most popular turning models at the Major League level, and personalized it with a black matte finish. The M110, developed in 1944, is one of Louisville Slugger's oldest turning models still being used today and featurings the lightest swing weight of Louisville Slugger's PRIME models. This model uses a denser starting billet to create a more consistently hard bat and a slightly thicker handle for a balanced feel, giving you maximum control when you bring the bat through the zone. All MLB PRIME bats -- made exclusively with the MLB grade wood, a standard met by only 3% of our wood -- now feature EXOARMOR, a revolutionary finish that is twice the hardness of a regular bat.
