About the Wilson Staff D300
The D300 was Wilson's distance game-improvement iron, announced on 10 January 2017 and on sale from 23 January. Its FLX Face technology used Power Holes filled with TE031 urethane running all the way around the perimeter of the face, which Wilson said left about three quarters of the face free to flex, and weight pods machined from 17-4 stainless steel sat in the heel and toe of a wide, relieved sole. Lofts step in a widening progression from a 20.5-degree 4-iron to a 43-degree pitching wedge, with a 29.5-degree 7-iron, about a degree stronger than the D200 through the middle irons. The stock set is 4-iron through pitching wedge with a 48-degree gap wedge, and a 54-degree sand wedge was sold to match. Figures below are the standard men's steel-shaft specification.

What are Power Holes on the Wilson Staff D300?
They are slots around the perimeter of the face, filled with TE031 urethane, that let most of the face flex independently of the body. Wilson called the system FLX Face.
How do the D300 lofts compare with the D7 that replaced it?
The D7 is roughly a degree stronger through the middle of the set. The D7 7-iron is 28 degrees against the D300's 29.5, and the pitching wedge is 43 degrees in both.
Finding a used set
The Wilson Staff D300 is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
- 2nd Swing Golf 'Wilson Staff D300 Iron Set' specification table (club, loft, length, lie, swing weight, 4-iron through SW) — retrieved July 2026. Retailer-published table, not a Wilson spec sheet. Lengths and lofts here are the ones used in this file.
- Qsponge 'What is loft angle of Wilson Staff D300 Irons?' — a second user-posted table that matches 2nd Swing on every loft except the 5-iron (23.5 against 23.0) and supplies the 63.0-degree 8-iron lie used here. Its length column is shifted by one club relative to every other source and was discarded; its millimetre offset column was discarded too, so offset is omitted.
- Golf Monthly 'Wilson Staff D300 Irons Review' (6 March 2017) and Golfalot 'Wilson Staff D300 Irons Review' — independently confirm the 29.5-degree 7-iron and the 26-degree 6-iron, and the FLX Face, urethane-filled Power Hole and 17-4 weight pod construction.
- The Golf News Net 'Wilson Staff D300 irons: preview, photos, specs, release date' (10 January 2017) — announcement date, 23 January 2017 release, the 4-9/PW/GW set composition and the KBS Tour 80 steel and Matrix Speed Rulz A-Type 54g graphite stock shafts.
- The 5-iron loft is given as 23.0 following 2nd Swing, which fits the model's regular 2.5/3.0/3.5/4.0/4.5/5.0-degree gap progression; Qsponge's 23.5 would break it. Bounce and offset are omitted for want of a corroborated source.
- year_discontinued 2019 is derived: it is the announcement year of the D7, per this project's convention, not a sourced end-of-production date.
