Checking a used set? These are published factory specifications, not measurements of the clubs you own. Loft, lie and length may have changed through custom ordering or later work.
How to identify this generation
- The Pro suffix matters: check the head shape and cavity against Mizuno's side-by-side visuals.
- A matching loft chart cannot identify Pro versus standard Hot Metal.
What to notice in the specifications
- The Pro 7-iron is 28° and 37.25 inches in the standard row.
- The manufacturer lists the Pro range through GW, while standard Hot Metal adds a SW.
- Mizuno's comparison gives the Pro a smaller head length; identical angles do not mean identical construction.
What the chart cannot tell you
A loft figure alone does not predict carry distance or determine a suitable fit. Head design, shaft, strike, swing speed and delivery also matter. Check actual loft and lie with a qualified fitter when a used set's history is uncertain.
