Mizuno has extended its renowned iron range with a Pro version of the JPX 919 Hot Metal released last year. Aimed at providing ball speed benefits to better players who still want a compact-looking head.
The JPX 919 Hot Metal irons, crafted from a new high-strength metal called Chromoly 4140M, gave ball speed increases to many golfers. After listening to the wishes of many better players, Mizuno is launching the Pro version of this iron with a smaller profile, but one that contains all of the features of the original iron.
Chris Voshall, Senior Engineer at Mizuno, explains more about the Hot Metal line:
There has been a noticeable shift of better players towards the Hot Metal irons. We realised 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.
The JPX 919 Hot Metal Pro shares all the essential design characteristics and performance attributes of the original Hot Metal model, and is engineered to produce a blend of ball speed and soft, controllable landing angles.
The aforementioned high-strength Chromoly 4140M allows a new multi-thickness face which promotes the ball speed increase, while a seamless one-piece cup face construction ensures greater levels of feel despite the extra distance and launch being achieved.
Re-engineered Sound Ribs generate 'specific vibration patterns' which are the keys to this blade-style feel through impact, whilst a new, more durable Pearl Brush finish helps to soften the head’s lines in bright sunlight for a sleeker look.
The smaller, more workable playing profile of the Pro mode features a slimmed-down top line and sole, plus reduced offset to bring Chromoly 4140M ball speed and performance benefits to players with an eye for a more traditional style.
The JPX919 Hot Metal Pro represents a more marked transition into smaller scoring irons and wedges, with matching gap, sand and lob wedges available. They are engineered from a softer X30 steel and complete with precision-milled grooves and faces for improved spin and control around the greens.
Available from February 2019 at £120 per club, these could be the perfect sticks for you if you want that combination of a sleek, player's look with a bit of extra help for that odd time you don't quite get all of it. They sound pretty good in theory, and there's no doubting that they look fantastic, so if they fit what you are looking for then get them on your test-list.
