【Oct 2026 Update】T100 Irons: 2023 vs 2025 ModelsThe 7-iron goes from 34° to 33°. Not many golfers need to upgrade

Updated: Sep 13, 2026Contains affiliate links

The T100 is an iron that gets renewed every two years with almost no change in looks. A new model came out in August 2025, and more golfers started wondering "what's different from the last one?" and "is a used 2023 enough?" Compared on official materials, three things changed: loft, the long-iron construction and the grooves.

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.

2023 model: Titleist Japan's official product page. 2025 model: Titleist Japan's official T-SERIES spec table (checked Sep 13, 2026).

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 in the table above. The official wording is "1° stronger loft 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 official wording points to better performance from the rough. If I were choosing a used 2023 model, I'd look first at how worn the 7-iron-to-P grooves 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 date6-club set (#5 to P)Single clubs (#3, #4, W)
2023 modelAug 25, 2023¥165,000¥27,500
2025 modelAug 22, 2025¥178,200¥29,700

All are MSRP (incl. tax). Actual selling prices differ by shop.

The maker price is up ¥13,200. New stock of the 2023 model is already scarce, so buying it means mostly used.

Who should upgrade, and who can stay

Who can consider the 2025 modelGolfers 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 modelGolfers 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 suitsGolfers 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.

  1. Look at the model year on the sales page ("2023 model," "2025 model")
  2. If it isn't stated, ask for the 7-iron loft (34° is 2023, 33° is 2025)
  3. 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).
