Choose it if
- You often catch it thin or heavy and want the most help an iron gives.
- Your iron shots start right or fly low: 5.9 mm of offset gives the face more time to square.
- You want a higher flight: the 31° 7-iron is weaker than most.
Choose something else if
- You play left-handed: PING G740, sold left-handed, 5.0 of 5.

What changed in the JPX925 Hot Metal HL
Mizuno prints the same lofts for both, from a 25° 5-iron to the 55° sand wedge (a 31° 7-iron), and nearly the same sole (23.9 mm across the 7-iron against 23.7 mm). The JPX925 Hot Metal HL adds a 22° 4-iron, is a quarter inch longer from the 5-iron to the gap wedge, half a degree more upright from the 5-iron to the pitching wedge (a full degree in the gap and sand wedges), and has slightly less offset (5.7 mm at the 7-iron against 5.9 mm). Mizuno also rebuilt the face and put tungsten low in the 4- to 7-irons. Both are right-handed only.
New JPX923 HL sets are gone, so the choice is a used 923 or a new 925. Choose a used JPX923 HL for the same lofts for far less, if a set comes in your flex; choose the JPX925 HL for a new set in your shaft and flex, with a 4-iron if you carry one.

Build a whole bag around it, or check the lofts in the bag you carry.
Use the iron finder to compare sets for your usual miss, and check the set makeup and loft gaps before ordering. Between a game improvement and a super game improvement head, this is how to tell which one your strike needs.

How the 4.5 adds up
The forgiveness score is our reading of what Mizuno publishes about the head, from 1 to 5. It is not a test result. How every score works.
| Part | Points | Why |
|---|---|---|
| Head class | 4 | Super game improvement: the biggest, most forgiving iron head a maker sells. |
| Offset | +0.5 | 5.9 mm at the 7-iron, at or above our 4.5 mm mark. |
| Sole | +0 | Mizuno describes the sole ("23.7 mm across at the 7-iron") but not as wide. |
| Forgiveness score | 4.5 | of 5 |
The score rates the head only. Hand, flex and price decide which version you buy, not how forgiving it is. Its shafts and flexes are custom-order options, with no stock shaft named.
