Mizuno introduced a new material with so much additional ball speed that its engineers had to focus on feel and stopping power in developing the JPX923 Hot Metal – its fastest-flying and fastest-stopping irons.
Nickel chromoly is 35 percent stronger than Mizuno’s original Hot Metal material, enabling a high-energy clubface that is 8 percent thinner. The thinnest part of the sole has been extended 18 percent wider to create a broader high-energy area on the face for more consistent ball speeds.
Combined with Mizuno’s vibration controlling V-Chassis and deep center of gravity design, it allows for a high launch and controllable landing angle for increased stopping power.
There are three JPX923 HM fitting options – Hot Metal Pro, Hot Metal and Hot Metal HL (high launch) – retailing for $137.50 per club. Two additional JPX923 irons – Forged and Tour – will be available for $187.50 per club in February.
The HM Pro (available 4-iron through pitching wedge) is a player’s speed cavity that’s compact, with minimal offset for confident ball-strikers seeking maximum ball speed. It’s suitable for low-to-mid-handicap golfers.
The Hot Metal (4-iron through lob wedge) is a forgiving speed cavity suitable for mid-to-high-handicap golfers, featuring a full speed, high-stability cavity for straight flight and distance.
The HL (5-iron through sand wedge, right-handed only) is a higher-launching option for players with moderate swing speeds or aggressive shaft lean, also suitable for mid-to-high-handicap golfers.
“There are so many different kinds of players looking for increased ball speed from their irons, we needed more options for them at a fitting level, said Chris Voshall, the director of product at Mizuno. “The custom studios use shaft selection incredibly well to help with launch angle or slower swing speeds, but the JPX923 Hot Metal HL gives them a great new tool to work with.”
All JPX923 irons will be available through the Mizuno Custom program.
