Compare original iron specifications.
Choose two exact model generations to view their published stock loft, lie and length side by side. The comparison uses the manufacturer sources linked below; it does not measure used clubs or predict ball flight.
Read the differences in context
A lower loft figure is a stronger static loft, but a loft gap alone does not establish carry distance, trajectory or fit. Head design, shaft, delivery and strike matter. Read our loft guide before interpreting a difference.
Published lengths and lie angles refer to specific original builds. A used set may have been bent, reshafted or shortened. Confirm the actual head and its history with our used iron checklist, and use a qualified fitter for current measurements.
For a worked generation example, read how the 2016 and 2017 M2 irons differ. You can also browse every available iron generation before choosing two sets.
