The Curated Take

The Mizuno JPX921 Hot Metal Irons are ideal for someone looking for a game improvement iron with a traditional look and enhances feel. These irons are very forgiving and easy to hit. They are very long and very easy to launch. The soles are designed for optimal turf interaction for most players. They are not the most workable clubs. One constant with these in fittings and in my own testing is they like to launch high and go straight. Optimal spin to hold greens.

The Hot Metal Irons are perfect for the 10-15 handicap player rapidly improving, but still wanting a higher launching ball flight and lots of forgiveness. This iron set has the look of a true performance iron with the thinner top line. It is very attractive at first glance and one will be hooked once they hit it. A great iron choice!

Pros
  • These irons are the total package
  • Higher launching with the lower COG
  • Explosive off the clubface
Cons
  • Higher launching than most Game improvement irons

The JPX921 irons are a great option for someone looking at Mizuno equipment. They have a center backing to them that truly allows for pure contact. Off-centered strikes carry almost as far as center contact strikes. Anyone looking to upgrade for a fair price (around $1000) for a whole set will find success translate to their iron game.

Pros
  • Sleek, sharp design
  • Off centered striking still carries quite a ways
  • Increased ball swing when measured
Cons
  • Distance was comparable to old irons, was hoping for more distance
