The JPX919 Hot Metal provides a
benchmark in iron design , engineered for
the perfect blend of ball speed and soft ,
controllable landing angles . High -
strength Chromoly 4140M has paved the
way to a new multi - thickness face that
promotes astonishing ball speeds , while
a seamless one - piece cup face
construction ensures surprising levels of
feedback even at such unprecedented
ball speeds .
It shares the JPX919 Tour ’ s new stability
frame , which is open at the heel portion
to enhance stability , launch and a loft -
appropriate flight apex for controlled ,
soft - landing approaches . Re - engineered
Sound Ribs have been developed to hit
specific vibration patterns that ensure a
satisfying sensation through impact , with
the JPX919 Hot Metal featuring the same
Pearl Brush finish as the JPX919 Tour .
The JPX919 Hot Metal offers a steeper
transition into more compact scoring irons
and wedges , with set - matching gap , sand
and lob wedges available engineered from a
softer X30 steel and blessed with precision -
milled grooves and faces for improved spin
and control around the greens .
“ The most impressive thing about the
JPX919 Hot Metal is the launch control and
flight apex ,” says Chris Voshall , Senior
Engineer at Mizuno . “ 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 !”
