Titleist · Irons · 2021
T400
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
You're a slower-swinging, higher-handicap or senior player who wants maximum distance, height and forgiveness with Titleist build quality - and you don't mind a loud iron.
You want soft feel, a quiet iron, shot-shaping workability, the spin to hold greens with the longs, or a compact players' shape.
Pros
- A super distance iron - a 7-iron at close to 130 mph ball speed and ~190 yards carry
- A forgiveness machine - up to 100g of tungsten for an extremely high MOI, with bad swings still above a 1.42 smash
- A genuinely excellent Split Sole - it doesn't play as wide as it looks and glides from any lie
- Cleaner-looking than most super game-improvement irons, with a minimalist Titleist cavity
Cons
- Possibly the loudest iron on the market - a sharp 'clap' at impact that polarises
- Light, firm feel - sharper and less substantial than the rest of the T-Series
- Very low spin - get fitted so it doesn't cost you control and stopping power, and there is no shot-shaping
By dimension
Forgiveness
A forgiveness machine - the hollow head and up to 100g of heel-toe tungsten create an extremely high MOI, with not a single shot, even on bad swings, below a 1.42 smash factor, and stability that preserves ball speed off centre. Among the most forgiving irons made - a super game-improvement design.
Distance
A super distance iron - the 7-iron at close to 130 mph ball speed and around 190 yards of carry, with the 6-iron carrying as far as 195 yards, the very strong lofts and forged Super Thin L-Face driving it. Elite game-improvement distance, hard to beat.
Workability
Built purely for distance and forgiveness - an oversized head with the thickest top line and thickest sole in the T-Series, made to maximise forgiveness rather than shape shots, a pure super game-improvement iron. Very limited workability, by design.
Feel
Light and lively - a unique, light feel with a sharper, higher-pitched impact that contrasts with the solid, muted feel of the other T-Series irons, though feedback is surprisingly good. Acceptable feel for a super game-improvement iron, if firmer and less substantial than the rest of the line.
Sound
Loud - it may be the loudest iron on the market, impact creating a 'clap' that announces your presence with authority, a sharp, high-pitched note, though strike feedback is still good. A polarising, loud acoustic - the weakest of the T-Series.
Looks at address
Oversized but tidy for the class - the thickest top line and thickest sole in the T-Series, so thick you can see a little of the back at address, with a long, rounded profile, though the minimalist cavity gives a cleaner-than-expected look. A large super game-improvement shape, tidy for the category.
