Quick Questions

What is the difference between the JPX 921 and the all-new JPX 923?

The JPX 923 line from Mizuno features an all new V-Chasis with a Seamless cup face. These irons, the JPX 923, are made from a 35% stronger (435 Nickel Chromoly) steel that feels better coming off the club face and creates more ball speed. The new Seamless Cup Face on the JPX 923 also improves vibration patterns at impact for a more satisfying feel when compared to the JPX 921. Finally the JPX 923 feature slightly longer club heads in the more forgiving models to enhance ball speed on mishits.

Which irons should I play?

JPX 923 Hot Metal HL- The JPX 923 Hot Metal HL is perfect for the mid to high handicapper (10-20+) who needs a forgiving iron that will launch high and help improve distance. The JPX 923 Hot Metal HL is a higher launching model for players with moderate swing speeds or aggressive shaft lean. These irons feature modern strong lofts and will be geared towards maximum distance and forgiveness.

JPX 923 Hot Metal - The JPX 923 Hot Metal is perfect for the mid to low handicapper (7-15) who is looking for a combination of high launch, high ball speed, and high forgiveness. The JPX 923's deliver solid, consistent performance on each and every shot. They will be more forgiving then the Hot Metal Pro and more workable then the Hot Metal HL. The Hot Metal is the most popular choice in the new Mizuno JPX 923 product line.

JPX 923 Hot Metal Pro - The JPX 923 Hot Metal Pro is perfect for the low handicapper (0-6) which is looking for more traditional lofted irons, with a thinner topline, and a more workable profile. The Hot Metal Pro Irons, while still forgiving, will be much more responsive on mis-hits. This is great for shot-shapers who want a little bit of forgiveness from their iron head
