What the differences mean
At the 7-iron, the Apex 21 is 30.5° and the Apex Pro 21 is 33°, a 2.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Apex 21 should carry roughly 8 to 10 yards further with that club, on a slightly lower, shallower flight than the Apex Pro 21. Across the 9 clubs both sets share, the Apex Pro 21 averages 2.2° weaker, with the largest gap at the 5-iron (23.5° vs 26°). The pitching wedges are 43° and 45°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping.
The Apex 21 is a players distance iron and the Apex Pro 21 a players iron, so they sit one step apart on the forgiveness scale. The Apex 21 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 Pro 21 trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The Apex 21 is listed as forged, multi-material and the Apex Pro 21 as forged body with a hollow long-iron construction and urethane microspheres. The Apex Pro 21'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 21, at some cost in feel. Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.
Both sets were introduced in 2021, 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 21 is the weaker-lofted set — up to 2.5° weaker than the Apex 21. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.

Yes. The Callaway Apex 21 7-iron is 30.5° against 33° for the Apex Pro 21, 2.5° stronger, which is worth roughly 8 to 10 yards of extra carry with the same swing.
What is the loft difference between the Callaway Apex 21 and Apex Pro 21?
At the 7-iron the difference is 2.5° (30.5° vs 33°). The largest gap on a shared club is 2.5° at the 5-iron, and all 9 shared clubs differ.
Which is better for higher handicap golfers, the Callaway Apex 21 or the Apex Pro 21?
The Callaway Apex 21. As a players distance iron it is the more forgiving design, suited to roughly 5 to 15 handicaps who want extra distance from a compact head. The Apex Pro 21 is a players iron, better suited to roughly scratch to 10 handicaps.
Do the Callaway Apex 21 and Apex Pro 21 have the same lie and length?
At the 7-iron, yes: both are 62° lie and 37 inches long.
