Grand Prix GPN-0002 Iron

Today, I tested this golf club.
The test club is the GRAND PRIX GPN-0002 Iron, 7-iron model.

The shaft is a Dynamic Gold.
The club length is 36.5 inches, with an S200 shaft flex and a low kick point.

It’s been a while since I’ve come across a GRAND PRIX iron.
GRAND PRIX is best known for its outstanding drivers, but I’ve tested one of their irons before. This time, it’s a muscle-back iron, which naturally piqued my interest.
Even though I knew it wouldn’t be as forgiving as a cavity-back, the stunning design drew me in instantly. Perhaps the challenge of mastering such a demanding club is part of its allure.

The toe features the iconic fighter jet logo, a signature of GRAND PRIX.
It’s an unmistakable hallmark of the brand.

This club has a traditional, orthodox shape with a compact head.
Although this is an older model that’s been discontinued, golf clubs often retain their beauty even as years pass. The difference between this and more modern irons was immediately apparent. It clearly draws from the lineage of older, classic clubs.
Muscle-back irons are less common now, but they used to be just as prevalent as cavity-backs. Over the years, irons have evolved significantly, becoming more forgiving and easier to use through various innovations. However, this iron lacks those modern adjustments.

The sole is very narrow, giving it a classic vibe.

The hosel is engraved with “GRAND PRIX MADE IN JAPAN.”

The neck is quite long, a feature typical of older models.
Such a long neck might not be as well-received in today’s market. The combination of the narrow sole and extended neck suggests a high center of gravity.

The heel appears to have a cavity.
While not common in modern irons, this was a standard design in the past.

Unlike the wider heel designs found in many modern irons, this one has a tapered neck, giving it a sleek look.

The face lacks milling, a feature that highlights its older design.
Despite its simplicity, many classic irons with this type of face were renowned for their performance.

The swing felt great—timing was easy to find, and the smaller head made it easier to sense the shaft’s movement.

Addressing the ball felt incredible—it’s simply the best.
The sleek, compact head gives it a sharp, clean look that makes the ball stand out. Although it’s an older iron, it has an undeniable elegance. It’s like the James Dean of golf clubs—timelessly cool.
The top line is beautifully shaped, and its aesthetics are truly captivating. GRAND PRIX may not be widely associated with irons, but this design could redefine that perception.

Testing Begins

The feel at impact is soft and superb.
This forged muscle-back offers excellent feedback and a sense of “holding” the ball. While many modern irons have a springy feel, I prefer this type that lets you “push and guide” the ball from impact to follow-through. This extended contact time enhances control and workability.
Those who prefer a springy feel may not enjoy this as much.

When it comes to launch, this iron is clearly designed for hitters rather than casual players.
Unlike modern, forgiving irons, this high-CG design demands a downward strike to get the ball airborne.

The stability is what you’d expect from a traditional muscle-back—it’s honest but not forgiving.
The sweet spot is small, making it less forgiving on mishits. Unlike modern irons that offer forgiveness across a wider area, this iron emphasizes precision.

Distance performance is far from today’s distance-focused irons.
There are no features to boost distance. Instead, it prioritizes precision, emphasizing consistency and control over distance.

The workability is outstanding.
Its responsiveness allows for a variety of shots, making every swing feel fresh and exciting. Unlike modern irons that limit curve shots, this iron’s sensitivity makes shaping shots effortless.

Post-Test Impressions

This iron suits players who want to shape their shots rather than rely solely on straight ball flights.
It’s neutral, accommodating both draw and fade hitters.

This iron doesn’t cater to the player; instead, it challenges you to rise to its level.
Rather than offering excessive assistance, it encourages the player to refine their skills.

While it’s less forgiving and might lead to more mishits, these experiences can help players improve their skills.

Players who enjoy the sensation of hitting high-CG irons will appreciate this club.
Golf isn’t just about scoring—it’s also about enjoying the feel of each shot.

Although modern irons incorporate various technologies, older designs like this one challenge players in unique ways.

This iron brought back memories of practicing endlessly as a beginner.
Even now, I’m as passionate about golf as ever. GRAND PRIX continues to inspire, and I look forward to what’s next.
