Features
Mizuno created their JPX family of irons with one goal in mind – drawing in younger audiences who preferred not playing shiny musclebacks from other brands. Their efforts proved highly successful thanks to Brooks Koepka, who purchased one set when Nike pulled out, going on to win and defend his US Open, then claim both US PGA tournament titles in 2019. He single-handedly revived Mizuno’s iron business; furthermore, the JPX 921 Tour expands its market presence further as tour professionals prefer irons from another brand over competing products from one or another brand.
These irons are made with Grain Flow Forged HD for an exceptionally soft feel, featuring thinner clubfaces than previous JPX irons and featuring beveled trailing edges to increase ball speed while the GD-Stabilizer frame and wider CNC back milled slot increase stability; all this together brings faster ball speeds from Mizuno entire body forged irons than ever before.
As is typical with Mizuno players’ irons, the JPX 921 Tour boasts ample forgiveness and exceptional shot control, making them a solid option for players seeking an ideal balance of long iron forgiveness and scoring iron precision. Furthermore, its toe weight can be adjusted lower, making these irons even better for shaping shots.
As well as having a longer CG distance from their shaft axis, these irons also feature narrower soles in shorter irons to improve turf interaction and make them easier to use in rough or off-the-fairway conditions.
As with other models in its range, the JPX 921 Tour comes with both standard and Pro versions for players to select from. The standard offers more of a classic profile and lower offset, while the Pro offers more compactness with higher degrees of balance. Both options provide excellent players irons.
Design
The JPX 921 Tour irons are among the more forgiving irons on the market, providing plenty of forgiveness without being quite as forgiving as blade irons. While its forgiveness may not match that of blade irons, its popularity remains among golfers who like working the ball instead of hitting spinful shots that depend on spin. They’re also great options for those struggling with mishits due to their relatively large clubface, which features less mass towards their toe.
The new Mizuno JPX 921 Tour iron looks very different from its predecessor and was created to meet modern players’ needs. It boasts a highly compact appearance with a smaller head than many of its rivals to allow maximum control for players during shots. Plus, with thinner toplines and soles than other Mizuno irons, this model looks sporty!
Although the look of the JPX 921 Tour may be eye-catching, its feel may not live up to expectations. While centered hits yield soft impact sounds that produce small impact sounds when hit squarely on, shots outside the sweet spot tend to feel duller and less complete than comparable cavity back irons – this lack of softness and fullness could make the club appear less responsive when miscued and may take some golfers some time to adapt to.
Though it offers less appealing off-center strikes, the JPX 921 Tour does offer outstanding stability for scoring irons thanks to a broader back-milled slot and complex face geometry that combines Mizuno’s fastest peak and average ball speeds ever seen from fully Forged irons. Furthermore, these scoring irons utilize Grain Flow Forged 1025E Pure Select Mild Carbon steel technology, which gives golfers an unmistakable and unrivaled Mizuno feel.
Mizuno uses forged material, which is much more challenging than steel, to produce thin faces for greater impact tolerance and consistency across the clubface, helping it achieve excellent forgiveness for forged irons. Furthermore, their improved Stability Frame with toe bias weighting promotes longer, straighter ball flights when off-center strikes occur.
Performance
Mizuno’s JPX921 Tour irons are designed to fit a broader range of players than its previous iterations; available both left- and right-handed versions with lofts pre-adjusted for ideal distance gapping, it features left- and right-handed versions available as a combination set. Available with long irons (4-5) followed by mid and short irons (6-GW). Loft adjustments have also been pre-set so as to maximize distance gapping potential.
Mizuno’s Grain Flow Forged HD process uses 1025E pure select mild carbon steel and features their Stability Frame with toe bias weighting to promote longer, straighter, and more consistent ball flight even on off-center strikes. For enhanced feel, the area behind impact has thickened significantly, while narrower sole-scoring clubs ensure smooth turf interaction in areas where precision is most crucial.
Mizuno claims that their JPX921 Tour produces greater average distance than previous generations, which indeed held in our tests with both Hot Metal and Pro versions of this club making exceptional levels of space. Unfortunately, average flight seemed to want to move into the wind at times – likely due to relatively high spin rates across their range – though shaft upgrades would help mitigate this problem.
As with other members of the JPX family, the 921 Tour iron is designed for better ball strikers who appreciate working the ball. Its muscle back geometry and stable frame structure combine in an intimate shape that better players prefer at address; further enhanced with a pearl brush finish to reduce glare and minimize distraction when standing over it.
This impressive-looking and performing forged player’s iron should meet the needs of a variety of golfers. Its smaller size and conventional appearance should appeal to many, while its outstanding feel, workability, and consistency should help even poor ball strikers find success with it.
Value
Mizuno’s JPX 921 Tour iron stands out in their lineup as it fills an intriguing gap between their forged player’s irons and blade irons. Though not as sleek or thin as blades, the 921 Tour still provides long, large hitting surfaces and excellent ball-flight control and forgiveness for better players. Furthermore, its lower price point compared to some high-end irons offers terrific value.
Mizuno irons, including the 921 Tour, are made using its Grain Flow Forged HD process from mild carbon for an exceptionally soft yet consistent feel across their face. Furthermore, these irons boast narrow sole and toe bias weighting to enhance stability at impact – one reason many professionals favor Mizuno over other brands.
The 921 Tour clubhead design is very similar to that of an MP-20 MB but with some key differences. The JPX Tour features a higher MOI for greater forgiveness and off-center hits; additionally, it is built with a lower profile compared to its counterpart MB series clubs, which makes its arrowhead shape appear more natural at your address and in your bag.
Mizuno puts great thought and care into crafting irons with great feel, such as the 921 Tour. Mizuno designers leveraged research into vibration patterns to redesign weighting in both clubhead and sole for improved feel at impact, making the px 921 Tour one of the best-feeling irons available on the market.
One aspect that sets this Mizuno iron apart from others is its absence of a 3-iron, due to the company analyzing custom orders and finding that golfers weren’t ordering 3-iron sets with them. Mizuno made this intelligent decision that makes their entire collection simpler to purchase.
The Mizuno JPX 921 Tour iron is an ideal choice for handicapped golfers seeking tour-level performance at a highly reasonable price. Its compact size and traditional appearance will appeal to most golfers who prefer working the ball from the fairway rather than rough; however, mid or high-handicappers should avoid this iron as its lack of forgiveness won’t allow them to succeed on the course.
