Specification comparison

Highlighted cells differ between the two sets. Lofts and lies are factory standard.

Lofts compared

What the differences mean

At the 7-iron, the Apex MB (2024) is 34° and the Apex Pro (2024) is 33°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Apex Pro (2024) should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the Apex MB (2024). Across the 8 clubs both sets share, the Apex Pro (2024) averages 1.1° stronger, with the largest gap at the 3-iron (20.5° vs 19°). The pitching wedges are 46° and 45°; the stronger one leaves a 5° jump to a 50° gap wedge, which matters when planning wedge gapping.

The sets are built differently: the Apex MB (2024) runs 3-iron to PW (8 clubs), the Apex Pro (2024) 3-iron to AW (9 clubs).

The Apex MB (2024) is a blade iron and the Apex Pro (2024) a players distance iron, so they sit 2 steps apart on the forgiveness scale. The Apex Pro (2024) is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 5 to 15 handicaps who want extra distance from a compact head. The Apex MB (2024) trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits low single-digit handicaps who strike the ball consistently.

The Apex MB (2024) is listed as one-piece forged muscle back and the Apex Pro (2024) as forged hollow body with a cup face. The Apex Pro (2024)'s hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the Apex MB (2024), at some cost in feel. The Apex Pro (2024) adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch. The Apex MB (2024)'s muscle-back shape keeps mass directly behind the strike for feedback and control, where a cavity spreads it to the perimeter for forgiveness.

Both sets were introduced in 2023, so this is a choice between two models from the same lineup rather than an upgrade: Callaway designed them to sit side by side for different players.

Which should you choose?

The Apex Pro (2024) is the stronger-lofted set — up to 1.5° stronger than the Apex MB (2024) on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
