A benchmark in iron design, Mizuno JPX 919 Hot Metal Irons strike a balance of launch, speed and control. The high-strength Chromoly 4140M construction combines with a seamless cup face to produce the highest ball speed ever found in a Mizuno iron. A Stability Frame design opens at the heel to enhance stability, launch and loft appropriate flight apex for soft landing on approach shots. Re-engineered sound ribs produce the unmistakable Mizuno feel at impact.

The most impressive thing about the JPX 919 Hot Metal is the launch control and flight apex – the extra ball speed and distance doesn’t come from low-flying bullets. We work the design backwards from the correct landing angles. These are irons for the golf course, not just the launch monitor.
