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.
