Mizuno has extended its JPX919 Hot Metal Series with a Pro model, targeting better players seeking compact looks with the ball speeds of Chromoly 4140M.
Earlier this year, Mizuno unveiled the new JPX919 family of irons comprising JPX919 Tour, JPX919 Forged and JPX919 Hot Metal, with each model engineered from different base materials to help enhance performance for particular swing types.
The JPX919 Hot Metal, crafted from a new high-strength metal called Chromoly 4140M, known for its ball speeds, and now the brand is launching a new Hot Metal PRO version of this iron with a smaller profile in response to demands from better players.
The JPX919 Hot Metal Pro shares all the essential design characteristics and performance attributes of the original Hot Metal model, engineered from for a blend of ball speed and soft, controllable landing angles.
High-strength Chromoly 4140M allows a new multi-thickness face that promotes ball speed, while a seamless one-piece cup face construction offers enhanced levels of feedback.
The head’s stability frame is open at the heel portion to enhance stability, launch and a loft-appropriate flight apex for controlled, soft-landing approaches, while re-engineered Sound Ribs are used to generate specific vibration patterns to offer a satisfying sensation through impact. A new, more durable Pearl Brush finish helps soften the head’s lines in bright sunlight.
The new Hot Metal Pro model features a slimmed-down top line and sole, plus reduced offset.
The JPX919 Hot Metal Pro offers a transition into more compact scoring irons and wedges, with set-matching gap, sand and lob wedges available, engineered from a softer X30 steel, with precision-milled grooves and faces for improved spin and control.
“There has been a noticeable shift of better players towards the Hot Metal irons,” says Chris Voshall, senior engineer at Mizuno. “We realized we could do more in that category and push the technology a bit further. The big surprise was how the ball speed and stability stayed near indistinguishable from the standard version, once we’d made the size and offset adjustment”
