Prime 919 Baseball Bat | Swing Weight | Louisville Slugger

Swing Weight

The Prime 919 has a mass index ranging from 740 on the 31” model to 1045 on the 34” model – these numbers equate to a specific swing weight “feel” when a hitter swings the bat. The lower the number is on the scale, the more balanced or lighter swinging “feel” the bat will have. Conversely, the higher the number the more “loaded” the swing will feel as the bat generates more momentum. Generally, an elite hitter will feel a difference in the swing weight for every 20 points on this scale. Compare and contrast the Mass Index scores across multiple bats to find your length, model and the bat the truly fits your game.
