What the differences mean
At the 7-iron, the JPX-923 Tour is 34° and the Pro 243 is 32°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Pro 243 should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the JPX-923 Tour. Across the 8 clubs both sets share, the Pro 243 averages 2.1° stronger, with the largest gap at the GW (51° vs 48°). The pitching wedges are 46° and 44°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping.
Both are players irons, built for roughly scratch to 10 handicaps. Small-to-mid cavity backs with traditional lofts, modest offset and workable shaping for low-handicap players. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The JPX-923 Tour is listed as Grain Flow Forged HD cavity back and the Pro 243 as Grain Flow Forged HD, multi-material. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The Pro 243 came out 1 year after the JPX-923 Tour, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The Pro 243 is the stronger-lofted set — up to 3° stronger than the JPX-923 Tour on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
