Mizuno Pro 243 Irons Specs & Design

The Pro243 irons are a high-performing cavity back option from Mizuno with this latest design combing power and feel from a new forging process.

Mizuno’s proprietary Grain Flow Forged technique has been honed in this latest release, so much so it now is a new patented method.

It features Chromium Molybdenum Steel (SCM420) Precision Forged and 4120 mild carbon steel in the long irons and Mild Steel S25CM Precision Forged and 1025E mild carbon steel from the 8-iron down.

The 243 irons also boast Mizuno’s revolutionary new Flow Micro-Slot Structure, which is designed to provide the perfect balance of speed, distance, forgiveness and trajectory.

Mizuno have also created the thinnest face yet to help deliver explosive ball speeds and “sensational” feel across the bag.

The combination delivers an iron that players and shot shapers will love, but with the added forgiveness that the 241 doesn’t have.

They are expected to be available in 4-iron (22 degrees) to Gap Wedge (51 degrees).

Verdict: Are Mizuno Pro 243 irons any good?

The Pro 243 irons are the mid-market option of the Pro Series, offering the ideal match for lower-handicap seeking the forgiveness of a cavity back.

They are equally suited to mid-handicap golfers who are seeking improved and more powerful ball striking and shot shaping possibilities.

This iron is a great all-rounded and much improved vs the Pro 223. Expect more consistency, distance and control with these in the bag.

What Mizuno says about the Pro 423 irons:

“Built upon the long-standing connection between Mizuno’s club engineers and its exclusive Grain Flow Forging plant in Hiroshima, Japan.

“A relationship which enables increasingly sophisticated designs to be crafted flawlessly into finished equipment.

“We’ve broken a lot of the boundaries that held back the ball speed of a forging. We’ve worked through it with materials and with processes to overcome a lot of the forging limitations.

“Every one of these irons is Grain Flow Forged, at least in the face and neck, if not more than that. We’re forging COR into the golf club as opposed to forging a part of a high-COR golf club.”
