Miura Golf doesn’t release new irons often. When they do, every design decision has been deliberate, tested, and held to a standard most manufacturers simply don’t attempt. The Miura PI-402 irons are the latest evolution of that standard — a multi-material player’s iron engineered to deliver modern distance performance without compromising the forged feel and classic aesthetics that have defined Miura for over five decades. Whether you’re a single-digit handicap or a committed ball-striker looking for a long-term set, the PI-402 is one of the most thoughtfully constructed irons on the market today.
Miura PI-402 Irons Overview
The PI-402 was built around a simple but demanding premise: bring contemporary distance technology into a Miura iron without disturbing what makes Miura irons feel the way they do. The result is an iron that will appeal to players of all skill levels — not because it’s been over-engineered for forgiveness, but because its performance package is wide enough to reward a range of ball-strikers while still delivering the connected, honest feedback Miura players expect.
Visually, the PI-402 makes an immediate impression. Compared to its predecessor, the PI-401, it features a more compact face length and increased heel height — a combination that produces a sophisticated, classic look at address that is rare in this performance category. It doesn’t look like a game-improvement iron. It looks like a Miura.
The Miura Forging Standard
Every PI-402 head leaves the Miura workshop in Himeji, Japan, built by craftsmen who have spent careers developing a level of skill that cannot be replicated at production scale. Miura’s forging process compresses the steel’s grain structure in ways that casting simply cannot achieve, creating a head that is more dense, more consistent, and more responsive at impact. The feel difference is not subtle. Golfers who have played cast irons for years describe the transition to a Miura forged iron as hearing the sound get quieter and the feedback get cleaner — as though noise has been removed from the system.
The PI-402 body is formed via hot rolling and pressing, a process that delivers high resilience for distance while refining the impact sensation. This is not a softness manufactured by adding inserts and foam — it is feel built into the material itself, shaped by the process, and finished by hand.
Why the PI Series?
Miura’s PI (Player’s Iron) designation identifies irons engineered for broad performance without abandoning the player’s aesthetic. Unlike the MB-101 blade or the KM-700 touring muscle back, the PI-402 incorporates modern construction methods — a multi-material body, a hot-rolled face insert, and a tungsten weight — to widen the performance window for golfers who demand both feel and results. It’s the most technologically sophisticated iron Miura has built for this category.
PI-402 Technology: What’s Inside
3mm Hot-Rolled Chromoly Steel Face
The face of the PI-402 is constructed from Chromoly steel — a chrome-molybdenum alloy known for its superior elasticity and durability compared to standard carbon steel. Hot-rolling this material before forming compresses and aligns the grain structure, making the face more resilient at high impact loads. The practical result: faster and more consistent ball speed across a larger area of the face. You don’t have to find the perfect spot to get a good number. The Chromoly face at 3mm thickness is engineered to perform across the entire hitting surface.
35g Tungsten Weight — Low and Centered
A 35-gram tungsten weight is strategically positioned low behind the impact zone — one of the heavier tungsten placements in this class of iron. Tungsten’s exceptional density allows Miura’s engineers to place a meaningful mass concentration in a compact physical space, driving the center of gravity down and back without increasing the overall head size. The effect is pronounced: effortless launch from longer irons, enhanced stability through the hitting zone, and a ball flight that climbs naturally rather than requiring manipulation. This is the technology that allows the PI-402 to play as long as modern irons while looking as clean as a traditional player’s club.
The Kissaki Sole
The PI-402 introduces Miura’s new KISSAKI SOLE — one of the most distinctive design elements in the iron. The name draws from “Kissaki” (切っ先), the precision tip of a Japanese sword, and the connection is intentional: just as the kissaki determines how a blade enters and exits its target, the sole geometry of an iron determines how it interacts with the turf at the moment of impact.
The Kissaki Sole features an advanced camber profile that balances effective bounce through contact. With a maximum sole width of 22mm, it is wide enough to provide stability and forgiveness on off-center strikes across a variety of attack angles and swing paths, while the camber design prevents the sole from dragging or digging in a way that disrupts trajectory or contact quality. Whether you play with a steeper attack angle or a shallower sweep, the Kissaki Sole adapts rather than forces.
Pocket Cavity and V-Shaped Mass Design
The internal structure of the PI-402 combines a pocket cavity with a V-shaped mass design that funnels weight toward the sole. This construction drives the center of gravity lower and more centrally, supporting higher launch, increased spin on approach shots, and enhanced forgiveness without the visual bulk of a deep cavity back. From the front, the iron looks refined and compact. From the back, the engineering is clear.
TPU Vibration Control Plate
Completing the construction is a TPU (thermoplastic urethane) vibration control plate integrated behind the face. This is a material choice with a specific purpose: TPU is highly effective at absorbing and redirecting the high-frequency vibrations that occur at impact — the kind that produce a harsh or metallic sensation in cheaper irons. In the PI-402, the TPU plate tunes the feedback so that what reaches your hands is connected and informative rather than buzzy or dead. Every strike feels like contact. The difference between a pure hit and a slight mishit is clear, but neither feels punishing.
Miura PI-402 Specifications
The PI-402 is available as a set from 4-iron through Gap Wedge (GW), with the following published specifications:
| Club | Loft | Lie | Face Progression | Weight |
|---|---|---|---|---|
| 4i | 21° | 61.0° | 3.5mm | 246g |
| 5i | 23° | 61.5° | 3.5mm | 253g |
| 6i | 26° | 62.0° | 3.5mm | 260g |
| 7i | 30° | 62.5° | 3.5mm | 267g |
| 8i | 34° | 63.0° | 4.0mm | 274g |
| 9i | 38° | 63.5° | 4.0mm | 281g |
| PW | 43° | 64.0° | 4.5mm | 288g |

Feel and On-Course Performance
Performance data tells part of the story. What it cannot capture is what happens the moment the PI-402 makes contact with the ball — that specific combination of sound, sensation, and ball flight that either earns an iron’s place in a bag permanently or sends it back to the demo rack after two rounds. The PI-402 earns its place.
The Chromoly face and hot-rolled construction produce a ball speed profile that competes with irons twice its price from major OEM manufacturers — but what distinguishes the PI-402 is what surrounds that speed. The TPU plate ensures the sensation at impact is dense without being muted, responsive without being harsh. You know exactly what happened at contact. Well-struck shots feel effortless and produce a penetrating, mid-to-high ball flight with controlled spin. The 35g tungsten weight makes longer irons launch with a ease that traditional player’s irons require ideal technique to achieve.
Forgiveness and Stability
The Kissaki Sole and perimeter-influenced mass distribution make the PI-402 genuinely forgiving for a player’s iron. Off-center strikes — particularly heel and toe misses — retain enough ball speed and directional stability to produce acceptable results. This is not maximum forgiveness. Miura has other irons for that. But it is protective enough that a slightly mis-hit 6-iron doesn’t become a bogey conversation. Golfers who split time between a blade and a more forgiving cavity back will find the PI-402 occupies that space credibly — and does it while looking far better than almost anything in the category.

Who Should Play the Miura PI-402 Irons?
Miura describes the PI-402 as designed for players of all skill levels — and the engineering supports that claim more credibly than most. The Kissaki Sole, Chromoly face, and 35g tungsten weight create a performance floor that catches off-center strikes without demanding perfection, while the pocket cavity and classic address profile ensure the iron doesn’t feel or look like it belongs in a beginner’s bag.
In practice, the PI-402 will be most at home in the bags of:
- Mid-handicap golfers (roughly 6–15) who have outgrown game-improvement irons and are ready for a player’s iron that rewards better ball-striking without punishing every slight mishit
- Single-digit players who want the Miura feel and aesthetic but need slightly more launch assistance and forgiveness than a pure blade provides
- Blade players transitioning to a more forgiving design without wanting to sacrifice the compact, traditional look at address
- Golfers who have played previous Miura PI-series irons and are looking for the modern technology upgrade the PI-402 delivers over the PI-401
If you’ve been playing a major-brand players distance iron and feel like you’re getting ball speed but losing the feedback loop that helps you improve, the PI-402 is exactly the kind of upgrade worth exploring. It gives back the feel without costing you the distance.
PI-402 vs. PI-401: What’s Changed
The PI-402 is not a minor refresh. Miura has made meaningful structural and aesthetic changes across the board. The most visible difference is in the address profile: the PI-402 features a more compact face length and a taller heel than the PI-401, delivering a more classic, sophisticated look that many players will find more reassuring than its predecessor. It looks less like a distance iron and more like a traditional player’s iron — while hitting it further.
Under the hood, the Kissaki Sole is entirely new, replacing the PI-401’s sole geometry with a more advanced camber profile designed for improved turf interaction across a wider variety of attack angles. The Chromoly face construction and the TPU vibration control plate represent technology steps that improve both performance and feel over the previous generation. If you played the PI-401 and liked it, the PI-402 is a straight upgrade in every direction.
