Titleist T400 Iron Review

Today, I had the opportunity to test this golf club.

The club I tested was the 7-iron from the Titleist T400 Iron series.

Tensei

It was equipped with a Tensei shaft.

The club has a loft of 26°, a length of 37 inches, a shaft flex of S (Stiff), a mid kick point, and a total weight of 366g.

This is one of Titleist’s latest iron releases.

Given the name “T400,” it likely belongs to their T-series iron family.

I recently tested the T300 irons, but the T400 feels more like a sibling model rather than a successor.

The unique shape and dimensionality of this club reminded me of a sperm whale.

It brought back memories of Herman Melville’s novel Moby-Dick.

Captain Ahab was one of the heroes of my childhood imagination.

Will these “whale-shaped” irons become the next big trend?

The head is large and has significant volume.

Rather than a traditional iron look, it gives the impression of being hollow-bodied.

It resembles a hybrid iron.

The cavity is deeply recessed.

While many irons these days are pocket cavities, this one features a concave center on the back face.

It’s what I’d call a “concave cavity” design.

Although rare, some cavity backs are “convex” instead.

The topline is slightly thick.

It has a wide sole.

What caught my eye was the unique sole design.

I’ve never seen a sole shaped like this before.

I imagine there must be a performance benefit to this design, but I wonder what exactly it is.

The neck is short and has a noticeable offset (goose neck).

The head is so large that it seems a bit top-heavy, but being a Titleist, it still manages to look refined.

The finish is high-quality and doesn’t feel cheap at all.

While the shape isn’t exactly my personal preference for an iron, the craftsmanship is impressive and actually appealing.

The shape of the back face reminded me of the 718 AP3 irons I tested previously.

There is no milling on the face.

The face is simple, symmetrical, and aesthetically pleasing.

It gives the impression of a soft impact feel.

The grip installed is a familiar, traditional type.

It’s different from the softer grips commonly seen on TaylorMade or Callaway clubs.

Despite the large head, the club feels surprisingly light overall.

Thanks to the carbon shaft, there’s a noticeable contrast between its appearance and actual swing weight, which I think many golfers will appreciate.

When I addressed the ball, I was pleasantly surprised by how clean and straightforward it looked.

The shine and finish instantly made me think, “Yes, this is a Titleist iron.”

While it’s a goose-neck type, the offset isn’t extreme.

Given its size, the offset feels moderate and well-balanced.

The rounded topline gives an impression of “enveloping” the ball rather than releasing it, which many golfers might prefer.

Large-headed irons often make it difficult to imagine face rotation through impact, but that’s not the case here.

Even with its large face, it feels very natural to swing.

Field Testing Begins

The feel at impact was quite good.

It wasn’t harsh or jarring—there was minimal shock on contact.

Rather than feeling sticky on the face, the ball launched off with a solid pop—definitely the sensation of a hollow-body club.

This distinct feel is characteristic of hollow irons, but in this case, it’s a positive trait.

Honestly, the feel is more like a hybrid iron than a traditional iron.

When we think of hybrid irons, we often think of long irons like a 3 or 4 iron—but this club brings that hybrid-like ease across the entire set.

The ball launches effortlessly.

The center of gravity appears low, and I suspect there’s some internal design ingenuity at play inside the head.

Though you can’t see it from the outside, it wouldn’t surprise me if there were tungsten weights strategically placed inside.

Golfers who prefer sweeping, shallow-angle swings will likely find this club very helpful.

The club offers excellent forgiveness and stability.

It’s clearly an automatic-type iron—very user-friendly and not demanding at all.

Its large head adds forgiveness and tolerance for mishits.

“Beautifully easy-to-hit iron” is a perfect way to describe the T400.

The distance performance is impressive—easily 1 to 2 clubs longer than standard irons.

Because it’s so easy to hit, I imagine many swinger-type golfers will benefit from it.

While it offers high launch and forgiveness, what stands out most is its distance capability.

If you’re looking for an iron that helps you hit longer without extra effort, this is definitely worth trying.

In terms of workability, its forgiving nature takes precedence, so it doesn’t react sharply to manipulations.

You can still hit slight draws or fades, but it’s not the best choice for players who want to hit intentional shapes.

Final Thoughts

This club offers great draw bias and helps players who typically struggle to square the face with larger irons.

As I tested this iron, I couldn’t help but think, “This is what you expect from Titleist.”

While the shape and size may not be to everyone’s taste, the overall build quality and performance are exceptional.

There’s no sense of cheapness—just a beautiful finish that leaves a great impression.

That’s a hallmark of Titleist craftsmanship.

There are many golf club brands out there, including numerous international ones, but among them, Titleist irons are my personal favorite.

They stand far above the competition in my view.

Even with all the advanced features, nothing about the club feels overdone—it’s just right.

After all, before hitting the ball, a golf club should also be pleasing to the eye.

My first impression was very positive, and after actually testing it, I didn’t find any major issues worth complaining about.

Of course, if you want to nitpick, you could say:

1. The head is too large 2. It goes too far 3. The feel isn’t quite right 4. It’s too light

—but those points come down to the type of iron this is meant to be, so it’s not really a fault.

I think this iron would suit players who feel more comfortable with drivers and fairway woods than with traditional irons and wedges.

It plays more like a wood than an iron, in a good way.

It’s forgiving, highly automatic, and not prone to big misses—ideal for on-course performance.

Personally, I’m not someone who seeks hollow-body construction in irons, nor do I feel I need it right now.

But among all the hollow irons I’ve tested, Titleist consistently delivers the best feel.

I hope Titleist continues developing irons with this kind of balanced performance.

Titleist T400 Irons 2019: Complete Review & Analysis

From the official website:

Introduction: The Distance-Focused Game Changer

The Titleist T400 Irons represent a significant departure from traditional Titleist designs, prioritizing maximum distance and forgiveness over workability. The T400 stands alone in the T-Series lineup as the most distance-driven, ultra-game-improvement iron Titleist offers. These hollow-bodied irons feature the largest head in Titleist’s T-Series lineup and incorporate advanced technologies specifically engineered to help golfers achieve greater distances with enhanced forgiveness.

Key Features and Technology

Hollow Construction Design

The Titleist T400 irons feature a hollow club head construction designed to create an extremely high MOI number. That means the hollow head gives more forgiveness and stability, especially when you don’t hit the ball in the center of the face.

Tungsten Weighting Technology

Up to 100 grams of high-density tungsten is strategically integrated into the heel and toe of the 5, 6, and 7 irons to lower the center of gravity and launch the ball high and far. This tungsten weighting system optimizes launch conditions and enhances stability across the face.

Split Sole Design

They also created a Split Sole shape that reduces digging and helps the club get in and out of the turf cleanly on every swing.

Performance Analysis

Distance Performance

Titleist promotes that every aspect of the T400 is about distance, and they certainly deliver. I was seeing consistent 6I smash factors in the high 1.4s and carry distance as high as 195 yards. That’s about 15 yards longer than my gamers.

Testing data reveals impressive distance gains:

Testing on the Foresight Sports GCQuad launch monitor, the T400 7-iron produced fast ball speeds close to 130mph, with carries around 190 yards on average
The average distance increase was consistent across the set, as I was gaining 5 yards per iron compared to my own set.

Forgiveness and Consistency

Equally impressive is the forgiveness. The most noticeable difference for me was the forgiveness of the T400 irons, when even the shots hit poorly from the heel resulted in a minimal change in distance.

Appearance Concerns: There is noticeable offset and the back of the sole on the 7-iron is visible at address, which some won’t like to see.
Less Workability: Limited shot-shaping capabilities compared to traditional Titleist irons

Who Should Play the T400?

Ideal Golfers:

Higher Handicap Players: Those seeking maximum forgiveness and distance
Moderate Swing Speeds: The T400’s are just plain awesome- especially in my experience in the 150-200 yard range (9-6 iron for me with these) which is where I sometimes struggle with consistency (11 HCP, driver speed 92-95).
Players Prioritizing Distance: Golfers who need help achieving greater yardages
Those Struggling with Consistency: The high MOI design helps stabilize off-center hits

Not Suitable For:

Low Handicap Players: Those requiring precise distance control and workability
Traditional Titleist Enthusiasts: Players who prefer classic blade-style appearance
Shot Shapers: Golfers who frequently work the ball left and right

Distance by Swing Speed

Based on testing data and specifications:

Moderate Swing Speed (80-90 mph):

7-iron: 170-185 yards carry
6-iron: 180-195 yards carry

Average Swing Speed (90-100 mph):

7-iron: 185-200 yards carry
6-iron: 195-210 yards carry

7-iron: 200+ yards carry
6-iron: 210+ yards carry

Note: These distances reflect the strong lofts (7-iron at 26°) and optimized launch conditions

User Reviews Summary

Positive Feedback:

Significant distance gains across the set
I was blown away by the distance gains, even on mis-hits. The ball traveled far and straight on off-center hits
Improved consistency for moderate-skill players
High, easy-launching ball flight

Critical Feedback:

I was hitting the stock shafted T400 irons anywhere from 2-10 yards longer than my current gamers (Mizuno JPX 825 Pro). That may sound promising, but the distance control was tough.
Concerns about appearance and offset at address
Less feedback compared to forged alternatives

Conclusion

The Titleist T400 Irons 2019 successfully deliver on their primary promise of maximum distance and forgiveness. T400 gets the absolute most out of your swing while still providing the playability of a Titleist iron along with that look, sound and feel that dedicated players demand. While they may not satisfy traditionalists seeking precise distance control and workability, they excel as game-improvement tools for golfers prioritizing distance and consistency.

The extensive tungsten weighting, hollow construction, and optimized lofts create a compelling package for mid-to-high handicap players seeking to maximize their iron performance. However, potential buyers should consider the trade-offs in shot control and traditional aesthetics.
