New Mizuno JPX919 Irons Released

Everything you need to know about the NEW! Mizuno JPX919 irons.


Mizuno’s new JPX919 Irons have been highly anticipated since USGA pictures leaked in July.  A run of 3 JPX iron wins at majors over 15 months (by a non-contracted player) have only added fuel to the fire of Mizuno’s unveiling.  The JPX919s are a highly engineered series of irons, evolved alongside Mizuno’s custom fitting program.  The three different models are each manufactured from their own unique steel, each with the properties to enhance the results from a particular swing type.



“It’s an exciting time when we finally get to demonstrate the results of 2 years worth of tweaks and improvements – especially on the back of the JPX900 irons, which were universally accepted as a great performers. 


The media anticipation is rightly around the Tour model after its predecessors success at the majors – but our fitters are more excited about the new Hot Metal and Forged options.  They’ve been testing for the last 2 weeks and the results are better than we’d dared hoped for.  When you’ve irons that look as good as this – performing as we now know they do, the impact should be pretty spectacular.”

Chris Voshall, Senior Engineer / Brand Manager


A more compact, streamlined evolution of Mizuno’s standout Tour Iron of 2017/18, establishing Mizuno as the non contracted manufacturer of choice amongst professionals.  The JPX919 Tour is surprisingly stable for its size, demonstrated in its tight distance patterns from off centre strikes – the critical benchmark for elite level shotmakers.  Grain Flow Forged HD (High Density) from a single billet of 1025E Pure Select mild carbon steel in Hiroshima Japan – for the softest, purest Mizuno feel yet.

Balancing ball speed and launch angle


A benchmark in iron design – the JPX919 Hot Metal combines an incredible balance of launch speed and soft, controllable landing angles.  The use of a high strength Chromoly 4140M and seamless cup face construction produces the highest ball speed from any Mizuno iron.  Mizuno’s new stability frame ensures that each iron within the set produces the correct flight apex – with landing angles steep enough to control shots into the green.

“The most impressive thing about the JPX919 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.” 

Chris Voshall, Senior Engineer.

JPX919 Forged / Boron infused steel

Forged feedback with performance ball speeds

With a new reverse milled clubface, the JPX919 Forged is Mizuno’s fastest ever forging in measured ball speed.  Balanced with Mizuno’s trademark workability and elevated Grain Flow Forged HD feedback – the JPX919 Forged is also Mizuno’s most versatile iron.


In the hands of a tour player searching a distance equalizer, or an amateur wanting feedback to evolve their game – the streamlined JPX919 delivers on every level.

“A deeper, wider milling across the back of the face makes the JPX919 Forged able to transfer more energy to the ball than any previous Grain Flow Forged irons.  None of that would have been possible without that small addition of boron into our steel billets – which gives that additional strength needed to reinforce the face.” 

David Llewellyn, Director of Golf R&D.
