When Titleist introduced the GT280, it quickly became a staple for players looking for a reliable, high-launching alternative off the tee that could still double as a long-range fairway weapon.
With the new GTS300 mini driver, Titleist set out to build directly on tour feedback from players like Justin Thomas and Cameron Young, focusing heavily on boosting stability without altering what made the original so playable off the turf.
The headline story is the expansion to a 305cc head volume. Utilizing a lightweight composite crown allowed Titleist engineers to reallocate discretionary weight deeper into the head, driving up inertia and making the head significantly easier to handle in terms of overall forgiveness on off-center hits.
Crucially, Titleist pulled off a masterstroke in design engineering: the entire volume expansion was executed horizontally. By keeping the exact same face depth as the GT280, the GTS300 retains its ‘low enough’ profile versatility from the turf, while incorporating a forged ATI 425 Titanium L-Cup face to protect ball speeds on lower-face strikes.
On the sole, Titleist added a dual-weighting system featuring 11g and 3g flat weights. Flipping these gives golfers and fitters what I would consider an almost essential tool nowadays to dial in launch and spin dynamics.
GTS300 Key Specifications:
Head Volume: 305cc
Standard Loft: 13.0° (SureFit Hosel Adjustable)
Standard Length: 43.5"
Sole Weighting: Dual-Weight System (11g / 3g Flat)
In hand, this is arguably the classiest-looking mini driver on the market today.
Titleist’s crown shaping is superb, blending traditional tour elegance with modern aerodynamic lines, while the expanded 305cc footprint gives you a noticeable boost in confidence behind the ball.
Off the tee, the slightly larger horizontal profile makes it feel far more like hitting a driver than its predecessor, which takes away any hesitation when stepping up on tight driving holes.
At address, the face is a touch lighter in finish than the black crown. This contrast makes it delightfully easy to pick out your target line and see some static loft. It provides a visual guide that isn't quite as stark as the crown-to-face contrast found across the standard GTS fairway range - a visual tweak I personally remain somewhat on the fence about - making the GTS300 look clean and cohesive at setup.
Both off the tee and off the deck, the GTS300 delivers performance that feels very "Titleist" - no unnecessary frills, just a solid, reassuringly crisp, and highly responsive feel off the face.
Ball speed is genuinely rapid. During testing on my Foresight Sports GC3 launch monitor, the GTS300 was absolutely neck-and-neck with the TaylorMade R7 Quad mini as the fastest mini driver I have tested to date.
Where the GTS300 really separates itself from the previous GT280 is in its manners on mis-hits. Heel and toe strikes stay online remarkably well, preserving distance in a way that feels far more forgiving. Yet, when you drop the ball onto the fairway turf, the preserved face depth means you don't feel like you are trying to sweep a giant driver head off the grass. It glides through cleanly, making light work of long approach shots.
Flipping the heavier 11g weight into the front port knocked off between 150 and 300rpm of spin for me on average, while moving it rearward made it feel a little easier to flight off the fairway, so you obviously have to make your mind up what you are prioritising when settling on a configuration.
If you loved the GT280, the GTS300 gives you virtually identical numbers, wrapped in a head that is noticeably more forgiving and confidence-inspiring. It retains everything that makes a mini driver such a potent weapon while polishing the aesthetics and adjustability to a premium standard.
Fitting options and aftermarket versatility remain top-tier with the GTS300.
The head is compatible with Titleist’s standard Fairway SureFit hosel sleeve, though it is worth noting that due to the clubhead's longer hosel design, a standard 43-inch 3-wood shaft will play a half-inch longer at 43.5 inches once installed.
Titleist offers an impressive lineup of featured shafts straight out of the box, including the Project X Titan Black alongside Mitsubishi’s Tensei 1K series in White, Blue, and Red. For those seeking custom upgrades, premium options include Graphite Design’s Tour AD DI, VF, and FI models.
The GTS300 comes in at an SRP of £499 for the featured shaft options, rising to £669 for the premium Graphite Design setups.
