The new Mizuno JPX923 Hot Metal 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. Regarding the 923 Hot Metal family, the standard Hot Metal Irons have a longer head length and thicker topline than the Pro. Compared to the new HL, Hot Metal has the same size topline and a fractionally shorter head length. If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard Mizuno warranty applies and satisfaction is guaranteed.
