About the Srixon I-403 AD
The I-403 AD was the forgiving, cast half of Srixon's early-2000s iron range — AD standing for the Accuracy and Distance branding it shared with the W-403 AD woods. Lost-wax cast from soft 255 stainless steel, it packs tungsten-nickel sole weights that Srixon claimed moved the centre of gravity lower than any competing iron, with variable hosel lengths and back weighting tuned through the set so the long irons launch easily and the short irons flight down for scoring. Progressive offset and a satin finish rounded out a club Srixon aimed at players of all abilities. The factory chart ran 3-iron to sand wedge and published no lengths, so those are omitted here.

Frequently asked questions
What is the loft of a Srixon I-403 AD 7-iron?
The Srixon I-403 AD 7-iron has a loft of 33 degrees and a lie of 62 degrees per Srixon's factory chart.
What does AD stand for on the Srixon I-403 AD?
Accuracy and Distance — the branding Srixon used across its 2004 403 AD woods and irons.
Are the Srixon I-403 AD irons forgiving?
Yes — they are the cast game-improvement model of Srixon's early-2000s range, with tungsten-nickel sole weights for a very low centre of gravity and progressive offset, while the forged I-302 served the better-player end.
Finding a used set
The Srixon I-403 AD ran from 2004 to 2005 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
- Srixon's official I-403AD specification chart (srixon.com/club_iron_403.asp with images/irons/403chart.gif, 2004, recovered via archive.org) — supplied every loft and lie above plus the SV-3000 graphite (65g S / 62g R, mid flex point) and True Temper Dynalite steel (114g S / 111g R, high flex point) stock shafts, and the 255 soft stainless + tungsten-nickel weighting and lost-wax casting construction
- The same archived page's marketing copy — Digital Impact design, lowest-CG claim, variable hosel lengths, progressive offset, satin finish, available in left hand and ladies
- Club lengths were not printed on the factory chart and no corroborated length table survives, so lengths are omitted rather than inferred; offset and bounce likewise. The loft/lie numbers themselves are factory data, so confidence is high
