About the Mizuno JPX-923 Tour
The Tour is the compact end of the JPX 923 family, a Grain Flow Forged cavity back for single-figure players rather than the game-improvement Hot Metal that carries the same number. Lofts are traditional — 34 degrees at the 7-iron, six weaker than the JPX 925 Hot Metal — and offset is uniform and tight, moving only 0.025 inches across the whole set. Mizuno announced the JPX 923 family in 2022 and the Tour and Forged models reached retail in February 2023.
