The Mizuno JPX923 Tour Irons are a compact player's cavity back that look and feel like a muscleback at impact. The irons are Grain Flow Forged HD at Mizuno's legendary facility in Japan and feature a thin layer of copper between the nickel and chrome to deliver unsurpassed soft feel. For added stability on off-center hits, Mizuno outfits the 923 with a reinforced V-Chassis with toe-bias. Mizuno elected to equip the 923 Tour with True Temper's Dynamic Gold 120, and for good reason. The shaft is easier-to-swing than the standard Dynamic Gold yet still provides tour-level accuracy. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard Mizuno warranty applies and satisfaction is guaranteed.
