NEW 2023 Mizuno JPX 923 Hot Metal Pro Irons

**Custom ordered, ships within 7-10 days** The new Mizuno JPX 923 Hot Metal Pro Irons are crafted from Chromoly 4335, which is 35% stronger than the Chromoly 4140M used in the previous generation, JPX921 Irons.  Chromoly 4335 is so durable that it's used in landing gear, transmission gears, and military aircrafts.  This new, extremely tough material allowed Mizuno's engineers to reduce face thickness by 8%, resulting in the thinnest face in JPX history.  The thinner, hotter face generates explosive ball speeds that toe the boundary of what the USGA legally allows.  Additionally, the previously mentioned speed and distance are available across a much larger area of the face.  The 923's more prominent sweet spot works harmoniously with the iron's revolutionary perimeter-weighted design, giving rise to prodigious forgiveness. In terms of the 923 Hot Metal family, the Pro Irons have more of a player's look with a shorter blade length and a thinner topline. Mizuno JPX 923 Hot Metal Pro Iron
