Irons【Nov 2026 Update】T100 Irons: 2023 vs 2025 ModelsThe 7-iron goes from 34° to 33°. Not many golfers need to upgrade
Updated: Nov 3, 2026Contains affiliate links
The T100 is an iron that gets updated every two years while barely changing its look. A new model came out in August 2025, and more golfers are asking, "What's different from the last one?" and "Is a used 2023 model enough?" Comparing official documents, three things changed: loft, long-iron construction and grooves. Every loft got 1° stronger, and the 7-iron went from 34° to 33°.
By the end, you will be able to decide whether to move up to the 2025 model or make do with a used 2023 model.
What I found after hitting it: I hit the 2025 T100 7-iron for about 15 balls on indoor TrackMan in September (about 24 degrees C inside, alone). The 5 balls struck on the centre had a consistent height, and I confirmed that the feel is tight. The 7-iron is 33 degrees, and it carried 155 yards with 6,400 rpm of spin. What gave me trouble was that 2 balls came out fat. I only compared the 2023 model against it in a golf shop in September and did not hit it. I bought neither.

Bottom line: if you're happy with the 2023 model, no need to hurry
The 2025 model has every club's loft 1° stronger. The 7-iron went from 34° to 33°.
The club numbers just shifted a little toward more distance. If the distance steps aren't giving you trouble on the 2023 model, there's not much reason to upgrade.
Those who can consider upgrading are golfers who carry the 3 and 4-iron and golfers buying a T100 for the first time.
In the hybrid article and the wedge article, I wrote that the same club number can have different lofts. Even under the same name, T100, loft differs between generations.
Loft by club compared
| Club | 2023 model | 2025 model | Gap |
|---|---|---|---|
| #3 | 21° | 20° | −1° |
| #4 | 24° | 23° | −1° |
| #5 | 27° | 26° | −1° |
| #6 | 30 deg | 29 deg | −1° |
| #7 | 34° | 33° | −1° |
| #8 | 38° | 37° | −1° |
| #9 | 42° | 41° | −1° |
| P | 46 deg | 45° | −1° |
| W | 50 degrees | 49° | −1° |
Every club is stronger by exactly 1°. The spacing between clubs (around 4°) is unchanged. Think of it as the shape of the distance steps staying the same while the whole staircase moved up a bit.
1° is roughly a few yards of distance. Judging from "about 10 yards per 3°" in the hybrid article, 1° isn't enough to change a club's distance noticeably.
What actually concerns me is below the pitching wedge. The 2025 model's P is 45°. If you carry wedges starting at 50°, the gap to the 2023 model (P = 46°) was 4°. In the new model it widens to 5°. If you upgrade, review the gap to your wedges at the same time.
Three things that changed in the 2025 model
Here are the changes Titleist's official news release lists, in order.
① Loft is 1° stronger (33° on the 7-iron)
As the table above shows, every club is 1° stronger than the previous model.
② The 3 and 4-iron gained a "muscle channel"
Only the long clubs have a changed head construction. In the official description, it's a change to raise launch and peak height in the long irons.
It doesn't concern you if you skip the 3 and 4-iron and build from the 5-iron. The T100 standard set is six clubs, #5 to P.
③ The grooves on the 7-iron to P are sharper and deeper
The score lines (face grooves) on the middle and short irons changed to a sharper-edged, deeper shape (the maker’s explanation). The change is meant to improve performance when hitting from the rough. I could not tell the difference in the grooves by eye. If I were choosing a used 2023 model, I would first look at how worn the grooves from the 7-iron to the P are, rather than at the year.
Conversely, some things haven't changed. The forged multi-material construction, dual cavity and variable bounce sole carry over from the 2023 model. The head shape hasn't changed much either.
The price gap
| Release date | 6-club set (#5 to P) | Single clubs (#3, #4, W) | |
|---|---|---|---|
| 2023 model | Aug 25, 2023 | ¥165,000 | ¥27,500 |
| 2025 model | Aug 22, 2025 | ¥178,200 | ¥29,700 |
The maker price is up ¥13,200. New stock of the 2023 model is already scarce, so buying it means mostly used.
What I learned from hitting the 2025 model
I hit the 2025 model’s 7-iron for about 15 balls on indoor TrackMan in September, alone and at about 24 degrees C inside. Watching the screen as I hit, the 5 balls struck on the centre had a consistent height. I confirmed that the feel is tight. The 7-iron was 33 degrees, as the maker states, and it carried 155 yards with 6,400 rpm of spin. 2 balls came out fat.
What gave me trouble were the 3 thin strikes. They went 10 yards to the right and the spin dropped as well. I widened my stance a little and hit again. Misses show up directly in direction and distance, so the point in this article that this is not a forgiving iron did not change after I hit it.
I only compared the 2023 model in a golf shop in September and did not hit it. The 7-iron loft looked 1 degree stronger on the 2025 model, as the numbers say. I could not see a difference in the score lines by eye. I have no numbers from hitting the 2023 model, so the gap between the two is only a comparison of the official numbers.
I compared it with the ZXi5 I used about 18 times from mid-September to October 2026, on how the misses show up. What I hesitated over was forgiveness versus feel, and I have no plans to buy. If I were choosing again, I would go with the ZXi5. For people who miss less often, I recommend the T100.

2023 model or 2025 model: which suits you?
| Who can consider the 2025 model | Golfers who carry the 3 and 4-iron and can't get the long clubs fully up Golfers buying a T100 for the first time (the 2025 model is what's available new) Golfers who hit a lot of iron shots from the rough |
|---|---|
| Who can stay with the 2023 model | Golfers building #5 to P who have no trouble with distance steps Golfers whose wedge spacing is set to the current P (46°) |
| Who a used 2023 model suits | Golfers who want to try a T100 but keep the price down Golfers who prioritize height and spin with a slightly weaker loft |
Before comparing generations, ask whether it suits you at all. The T100 is not a forgiving iron. Mistakes show up directly in distance and direction. It has the smallest head in the series, so there's little room to help you on off-center hits. I don't recommend this model for golfers looking for irons to reduce the spread of their misses. In the iron rankings, I line up the other four models by 7-iron loft.
How to tell them apart when buying used
They look very much alike. Deciding the year from a head photo alone is risky. Check in this order.
- Look at the model year on the sales page ("2023 model," "2025 model")
- If it isn't stated, ask for the 7-iron loft (34° is 2023, 33° is 2025)
- If you still can't tell, have a shop measure the loft
Buy without knowing the year and the spacing to your wedges or hybrids can be off. For any used iron, not just the T100, confirm the year and the loft together.

FAQ
Can I mix 2023 and 2025 models?
You can. But lofts shift by 1°, so adding a "2025 P (45°)" to "2023 #5 to 9," for example, narrows the gap to the 9-iron (42°) to 3°. If you mix, list the loft of each club first and then decide.
Does 1° more strength mean more distance?
Compared club by club, it leans toward a little more. But the whole set shifts by the same amount, so the "distance step between clubs" is unchanged. What affects your score is whether those steps line up, more than distance.
How does it differ from the T150, T250 and T350?
The T100 has the smallest head in the series. The higher the number, the larger the head, the stronger the loft, and the more the design prizes forgiveness (the T250 Launch Spec, built to launch the ball higher, is an exception with a 35° 7-iron). On the 2025 official specs, the 7-iron loft is 32° for the T150, 30.5° for the T250 and 29° for the T350, against 33° for the T100 (Titleist's by-brand page).
