The Hot Metal propels the ball very high and basically straight from almost everywhere; a very agreeable club—you don’t need to press to get out of sticky situations; heavyish head and wide sole blast through rough.

Distance Control

Above-average top-end power, perhaps a few yards past the JPX 900 Forged and a half-club beyond what most testers play; consistent distances across the entire face.


Not as maneuverable as many other irons in its class; feel doesn’t quite live up to the Mizuno benchmark but is still better than a lot of its peers; less comfortable around the greens than some guys expect.

Bottom Line

Longer and higher launching, the JPX 900 Hot Metal is a nice complement to the muchlauded JPX 900 Forged. If you like the sports car, here’s the hatchback: roomier, more comfortable, and a bit more practical for higher-handicaps. It’s a great choice for someone whose old MP’s are gathering dust.
