Mizuno JPX 919 Forged

The Mizuno muscle backs have always been aspiring clubs but many golfers who would love to play them don’t have the consistency that is needed to hit them. With the JPX 919 forged, this will be a different story. The new Mizuno JPX 919 forged is designed to be a longer, more forgiving option for golfers who want a classic looking club.  The JPX 919 Forged is Mizuno’s fastest ever forging in measured ball speed. Mizuno has designed this iron to appeal to a broader number of players that don’t have that consistency that you need for the other blades.

When Chris Voshall, Mizuno’s Engineer, was interviewed by many companies he said that the JPX 919 Forged irons are the most all-around, well-balanced club they make. The JPX 919 is good at everything! The feel, workability, distance, and launch are all good in this forged iron. But, this iron is not amazing in one particular category. That being said these irons have raised the stakes all around.

The JPX 919 are using the same HD Grain Flow forging process as the former JPX 900 Tour irons. When Voshall was interviewed, he noted that the forging process was difficult considering the stronger, boron-infused material used in these clubs compared to the soft 1025E Steel in the 900 Tour irons. Unlike the other two clubs, this small addition of Boron makes the steel billet 30% stronger. With the denser of the grains in the JPX 919, it allows them to thin the face and increase the bounce for more distance and ball speed.

Also, the Mizuno JPX 919 have a reverse milled face. With the new reverse-milled slot insert, it allowed Mizuno to move the weight deeper and more toward the toe. This helps the longer irons launch higher.  Another major change is that Mizuno redistributed some of the weight in the JPX 919 Forged irons, removing it from the heel and repositioning it in the toe. This shifts the center of gravity more into the center of the face and down slightly. The top line and the toe areas were reinforced to help enhance sound and vibrations created at impact. With removing the weight, it allows a deeper center of gravity for more easily flighted long and mid irons.

We recently conducted some testing on the Mizuno JPX 919 Forged. One of our Certified Custom Fitters compared the JPX 919 Forged to the JPX 900 Forged. They were both 7 irons with standard lie and loft. He used a True Temper Dyanimc Gold X100 shaft in both irons. Here are the results: 


While testing these two irons side by side, we noticed that the dispersion was a lot closer with the JPX 919. He was a lot more consistent and the numbers showed that as well. He said that he felt like he had more control over the new JPX 919 Forged irons rather than the older model. As you can tell in the charts the JPX 919, on average, carried about 2-3 yards farther and 4-5 yards total. We both were very pleased with that.  The thinner face helped the ball speed and distance as they said. With the JPX 900 the ball speed was 128.8, but with the JPX 919, it was a 130.3! The thinner face really works, it gave both; a faster ball speed and more forgiveness. We were very pleased with the results from the Mizuno JPX 919 Forged. This new forging process is worth trying for yourself! 

The Mizuno JPX 919 forged has the ultimate blend of ball speed, stability, and feedback within a more refined playing profile. With the combination of all the new elements and higher lofts have them going longer and are easier to hit especially with the long irons. 

These irons are available to demo at every location! There are 18 different shafts that you can custom order in the clubs and 16 different grips.
