Titleist 2021 T300 Irons - 3 Perspectives

This is a review of the 2021 model of the Titleist T300 iron.

Titleist first came out with the T300 iron in 2019, and the goal was to offer reliable game-improvement performance for committed golfers. Now, Titleist has revamped the T300 for 2021 to include 40% more tungsten and a new level of optimal performance.

The 2021 T300 iron is meant to be long and forgiving with a premium feel. But how do these claims hold up when put to the test? Is it worth putting the 2021 T300 irons in the bag?

I’ll try to answer all of these questions and more in this review. Here’s what I’ll be covering:

Note: Unless otherwise stated, stock shafts and stock grips are used when evaluating this club. In most cases, the golf clubs reviewed on Golfstead are acquired temporarily for testing purposes and are not purchased. The review that follows is based on the personal experience and research of the author. Because everyone’s swing and body are different, results with a particular club may differ from person to person.

What are the reviews like?

Critic reviews of the T300 irons are overall very positive. Golf Monthly gives them 5 stars, and they earned a gold medal on the Golf Digest 2021 Hot List for game improvement irons.

Customer ratings are just as good, if not better. They have average scores of 5/5 on Golf Galaxy, 4.1/5 on Global Golf, and 5/5 on The Golf Warehouse. If you’re skeptical of Titleist producing a game improvement iron that can compete with the best, worry not.

What are the features?

The 2021 T300 iron has been engineered to “improve, distance, launch and shot-making while providing maximum forgiveness” in a confidence-inspiring shape.

Max Impact Technology

First seen in 2019 models, this innovation was developed in partnership with the Titleist Golf Ball R&D department.

An enhanced polymer core is located directly behind the face. This ‘hidden power source’ dampens vibrations and sounds in a unique way, thus maximizing ball speeds across the face.

In short, Max Impact Technology improves the mass efficiency of the club, improves feel and feedback, and increases ball speed.

Variable Face Thickness

In the long and mid irons, the face gets thinner as you move towards the heel.

This is designed to improve performance in what has historically been one of the worst-performing mis-hit regions.

Tungsten Weighting

In addition to using 40% more tungsten in the head, Titleist uses a denser D18 tungsten, which is put through a 2000°F brazing process used in aerospace construction.

This leads to solid Tour-like feel while providing an optimal balance of forgiveness, speed and launch.

How do the irons perform?


Compared to the T400 which I just tested recently and whose results are still fresh in my mind, I was hitting the 2021 T300 about 7-9 yards shorter on average.

I have no issue with this, because in my mind, the T300 isn’t meant to be a “super distance” iron like the T400.

Nonetheless, these irons are still very long, and because they generate about the same launch and spin rate as the T400 while producing a little less ball speed, shots come into the greens more steeply and good stopping power.


It was clear from my tests that the 2021 T300 isn’t quite on par with the T400 in terms of forgiveness, although forgiveness is still very good overall and worthy of the game improvement label.

It really comes as no surprise, since you can think of Titleist’s T-Series line as gradually becoming more forgiving as you move from the T100 to the T400.

Smash factors on mis-hits were still pretty good and never really dipped below 1.4. The worst performance on the face tended to be in the toe area.

Playability & Trajectory

With the True Temper AMT Red stock steel shaft, the 2021 T300 iron gave me a high launch — higher than most irons I test. There was no particular fade or draw bias, and the spin was on the low side.

One thing that really stood out to me are the relatively soft landings of the T300. The T300 just doesn’t quite have that “explosive” ball speed that’s going to work against backspin. This is a big plus for me, as I place much more importance on controllability than pure distance.

The 2021 T300 isn’t a shotmaker’s iron. Workability isn’t that much better than the T400.

What about look, sound & feel?

The Look

As a game improvement iron, the 2021 T300 has a thicker shape and is wider from heel to toe than Titleist’s slimmer, more compact players models. It’s not as chunky as the T400, however.

Having said that, offset is quite minimal and the iron sets up more or less square at address. The Max Impact Technology is visible on the back of the club in the longer irons, while the back of the shorter irons (8+) have a lot less going on.

The shiny chrome finish of the 2021 T300 looks great, but it does bring out scuffs and scratches more compared to a brushed matte finish. This perhaps becomes an issue with higher handicap players who tend to mis-hit their irons more.

The Sound & Feel

The 2021 T300 produces a quite high-pitched and sharp “crack” at impact that almost sounds a bit clickey. In my tests, it was actually difficult to feel the ball coming off the face.

Impact tended to feel thinner towards the heel in the long and mid irons, which is consistent with the variable face thickness. Overall, though, impact feel was very solid.

The feel is not as responsive or soft as what you get with the T100 or even T200. For this reason, feedback is the least distinct in the T-Series of irons — even less distinct than the T400. You will generally have a tough time figuring out where you made contact on the face.

Where should you buy the 2021 T300 irons online?

For new 2021 T300 irons, you should check out Global Golf or Rock Bottom Golf. They can accommodate custom requests and offer payment plans, performance guarantees, and club trade-in programs to help you minimize the financial hit.

New iron models don’t stay new for long, and eventually the option for custom orders will disappear. At that point, you’ll have to look at off-the-rack T300s or even used sets.

For used 2021 T300 irons, your best bet is probably eBay. They are a fantastic source for golf equipment, both new and used.

Final Thoughts

The Titleist 2021 T300 iron offers excellent game improvement performance, but not so much that it sacrifices consistency and stopping power into the greens. The premium players-like feel will also give the T300 a boost in many golfers’ eyes.

The 2021 T300 is best suited for a golfer looking for a good amount of distance and forgiveness, but not on the extreme end of the spectrum like the T400.

I would have liked to see a little more clarity when it comes to mis-hit forgiveness. But other than that, the 2021 T300 iron has a little something for everyone.
