What the differences mean
At the 7-iron, the JPX-923 Forged is 30° and the Pro 245 is 30°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 8 clubs both sets share, the Pro 245 averages 0.3° stronger, with the largest gap at the 9-iron (39° vs 38°). The pitching wedges are 44° and 43°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the JPX-923 Forged runs 4-iron to GW (8 clubs), the Pro 245 2-iron to GW (10 clubs).
The JPX-923 Forged is a players iron and the Pro 245 a players distance iron, so they sit one step apart on the forgiveness scale. The Pro 245 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 JPX-923 Forged 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 JPX-923 Forged is listed as forged and the Pro 245 as Grain Flow Forged HD, hollow body multi-material. The Pro 245'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 JPX-923 Forged, at some cost in feel.
The Pro 245 arrived 1 year after the JPX-923 Forged, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The Pro 245 is the stronger-lofted set — up to 1° stronger than the JPX-923 Forged on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
