JPX919 Hot Metal

Combining an incredible balance of ball speed and launch angle, the JPX919 Hot Metal utilizes a high-strength Chromoly 4140M material with cup-face construction to produce what they say is the highest ball speed from anyMizuno iron.

But the real star of this show is the stability frame, again open at the heel portion, which helps players control launch and landing angles and ensure they’re able to land and hold greens. According to Chris Voshall, Senior Engineer, “We worked the design backwards from the correct landing angles. These are irons for the course, not just the launch monitor.”

For this set of irons, Mizuno also re-engineered the sound ribs to promote specific vibration patterns that give the irons a desired sound and sensation through impact – often described as that “Mizuno sensation.”

 

JPX919 Forged

For the JPX919 Forged, Mizuno added a trace amount of Boron to increase the steel billet’s strength by 30%, which allows for greater design capabilities. In essence, this makes the aforementioned iron Mizuno’s most versatile one yet.

In addition to the stability frame, the clubface is CNC milled from the sole up which in turn produces a larger minimum face thickness and increased ball speeds across the face on all strikes. Weight is also removed from the face which promotes a lower and deeper center of gravity, thus allowing players to flight their mid and long irons easier.

The folks at Mizuno know how serious you take your game, and the deliberate construction and painstaking research put into their irons reflect that. This new JPX919 line of irons is expertly crafted to provide you with shotmaking capability, forgiveness, and distance, and is, according to Mizuno, “Packed with your potential!”
