How to identify this generation
- A large red insert carrying the W/S shield fills the middle of a chrome cavity, with D100 lettering low near the toe.
What to notice in the specifications
- Wilson lists the sand wedge as a custom option. Gap and sand wedge share the pitching wedge’s 36 in length in this table.
- The D100 ES hybrid-iron set on the same site is a different product with its own heads.
Checking a club you own? These are the maker's published figures for an original build, not measurements of your club, and a source date is not the year it was made. Bending, reshafting or a hosel adjustment changes loft, lie and length, so identify the head by its own markings and have a fitter measure it when its history is unclear.
