What the differences mean
At the 7-iron, the MP-25 is 34° and the JPX-900 Forged is 31°, a 3° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the JPX-900 Forged should carry roughly 9 to 12 yards further with that club, on a slightly lower, shallower flight than the MP-25. Across the 7 clubs both sets share, the JPX-900 Forged averages 2.6° stronger, with the largest gap at the 4-iron (24° vs 21°). 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 MP-25 runs 3-iron to PW (8 clubs), the JPX-900 Forged 4-iron to GW (8 clubs).
Both are players distance irons, built for roughly 5 to 15 handicaps who want extra distance from a compact head. Forged or multi-material heads that keep a compact look while adding face technology and stronger lofts for distance. 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 MP-25 is listed as Grain Flow Forged with a micro-slot behind the face and the JPX-900 Forged as forged. 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 JPX-900 Forged came out 1 year after the MP-25, 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 JPX-900 Forged is the stronger-lofted set — up to 3° stronger than the MP-25 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
