About the Callaway Apex Pro 21

Apex Pro 21 is the tour end of Callaway's Apex family: a 1025 carbon steel forging with tungsten energy cores, urethane microspheres filling the cavity to damp vibration, and a hollow construction through the long irons. Lofts are traditional for a players iron — the 7-iron is 33 degrees, four weaker than the Rogue ST Pro of the following year — and offset is tight, from 3.56 mm at the 3-iron to 1.65 mm at the approach wedge.

Finding a used set

The Callaway Apex Pro 21 ran from 2021 to 2023 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.

Data compiled from:

2nd Swing Golf specification table for the Callaway Apex Pro 21 iron set (2ndswing.com) — supplied every loft, lie, length, offset and swing weight above, both stock shafts and the Golf Pride Z Grip.
Note on offset: the source publishes offset in millimetres (3.56 mm down to 1.65 mm), converted to inches here.
prnewswire.com 'Callaway Golf Announces New Apex Irons And Hybrids' — the Apex 21 family, including the Apex Pro 21, was announced on 12 January 2021, with pre-orders from 26 January and retail from 11 February; body forged from 1025 mild carbon steel.
Note: bounce is omitted — the source table did not carry a bounce column. Confidence is medium because the figures come from a retailer spec table rather than a Callaway spec sheet.
Status check, 29 September 2026: year_discontinued is 2023. Callaway launched the 2024 Apex Pro, CB and MB in August 2023 (golfwrx.com).
