Game Improvement Driver

Mizuno spent years known for buttery forged irons, and the ST190G was the driver that finally got serious golfers to take the brand seriously off the tee. It packs a 460cc titanium head with a forged SP700 titanium face, and that forged face is where Mizuno leaned on what it already knew. The result is a driver that launches high, holds its speed on off-center hits, and lets you dial in the setup.

The G in the name is the important part. This is the adjustable version of the 2019 ST190 line, with a sliding weight track along the sole on top of the adjustable hosel. You can shift the weight to fight a slice or flatten a hook, and you can turn the loft up or down at the hosel to fine-tune launch and spin. For a 2019 driver aimed at the game-improvement crowd, that is a lot of control in one head.

Don't expect a compact, low-spin tour head here. The ST190G wants to get the ball up in the air and keep it there, which is exactly what most mid-to-higher handicap players need. It rewards a smooth swing and stays stable when your strike wanders toward the heel or toe.

• Mid to higher handicappers who need help getting the ball airborne and want a taller, easier launch
• Players who fight a slice and want to move sole weight toward a draw bias to straighten it out
• Anyone who likes to tinker with loft and weighting to find their own setup instead of a fixed head

Frequently Asked Questions

What is the difference between the ST190 and the ST190G?

Both share the 460cc head and forged SP700 titanium face, but the ST190G adds a sliding weight track on the sole. That lets you shift the center of gravity to bias the ball flight toward a draw or keep it neutral. The standard ST190 has a fixed weight, so the G is the choice if you want that extra adjustability.

Is the Mizuno ST190G adjustable?

Yes. It has an adjustable hosel for changing loft up or down, plus the sliding sole weight for tuning shot shape. You can raise the loft to launch higher or lower it to bring the flight down, and move the weight to fight a slice.

Does the ST190G launch high?

It does. Mizuno built it to get the ball up, using the Wave sole and the hot forged face to add launch and hang onto spin low on the face. If you already hit a high ball you can dial the loft down at the hosel, but the head's natural tendency is a taller flight.

Is the ST190G forgiving on mishits?

For a 2019 driver it holds up well. The forged SP700 face keeps ball speed across a wider area, so heel and toe strikes lose less distance than they would on a stiffer cast face. It is a stable, game-improvement head, not a compact low-spin tour model.

What loft options did the ST190G come in?

It came in 9.5 and 10.5 degree heads, and the adjustable hosel lets you shift each one a couple of degrees in either direction. Most players in the game-improvement bracket do well starting with the 10.5 for the extra launch.
