PXG’s Battle Ready II Putters feature a thin-walled hollow body construction, injection molded core, and the thinnest face in putters. The result is a high moment of inertia (MOI) design, coupled with a remarkable sound and feel on every stroke. The Blackjack is a bold, high MOI mallet-style putter with exceptional stability, forgiveness and clean alignment features letting you double down your bets as you sink more putts.
