Weak Grip
A weak grip rotates both hands toward the target side of neutral — fewer than 2 knuckles of the lead hand visible at address — which leaves the face open longer and is a common hidden cause of a slice.
A weak grip is created by rotating the lead hand counter-clockwise (for a right-handed golfer) relative to neutral, so that at address the golfer sees fewer than 2 knuckles — sometimes none — of the lead hand, and the "V"s formed by both thumbs and forefingers point up toward the chin or lead shoulder rather than the trail shoulder.
A weak grip leaves the clubface more open relative to the swing path for a given amount of forearm rotation, which means the golfer needs to actively rotate the forearms more aggressively through impact just to arrive at a square face. Many recreational golfers who slice do not realize the grip is contributing, because the grip feels comfortable and the ball still starts close to the target line — it curves away because the open face at impact adds side-spin. A weak grip is also common among golfers who were taught to "hold the face open" for control and unintentionally over-applied that idea into the grip itself.
A weak grip is not always a problem: some accomplished players deliberately use a slightly weak lead-hand position paired with an aggressive release to hit a controlled fade, and putting grips are frequently intentionally weakened to quiet hand action. But as a full-swing grip for someone fighting a slice, a weak grip is one of the first things worth checking and correcting before assuming the fault lives entirely in the swing path.
Example
A player sees zero knuckles of their lead hand at address and slices every iron; strengthening the grip to a neutral 2-knuckle position removes the slice within a practice session.
Why it matters
A weak grip is a hidden, easy-to-miss contributor to a chronic slice — checking it first can save a golfer from rebuilding an otherwise sound swing path.
How it shows up on video
From a face-on address frame, a weak grip shows fewer than 2 lead-hand knuckles visible and both "V"s pointing up toward the chin rather than the trail shoulder.
Common mistakes
- Only looking at swing path when diagnosing a slice — grip is a faster, cheaper thing to rule out first.
- Weakening the grip further to try to "hit it straighter," which usually opens the face more and makes the slice worse.
- Confusing a weak grip with weak grip pressure — grip strength refers to hand rotation on the handle, not how tightly the club is held.

Frequently asked questions
How do I know if my grip is too weak?
Look down at address: if you see zero or one knuckle of your lead hand, and the "V" between thumb and forefinger points toward your chin instead of your trail shoulder, your grip is weak.
Is a weak grip always bad?
No — some players use a slightly weak grip intentionally to support a controlled fade, and it is common in putting. As a full-swing grip for a player fighting an unwanted slice, though, it is usually worth strengthening toward neutral.
Related terms
- Neutral GripA neutral grip has the lead hand rotated so 2–2.5 knuckles are visible at address and the trail hand's palm faces the target — the "middle" grip position that squares the face without extra hand manipulation.
- Strong GripA strong grip rotates both hands further to the trail side than neutral — 3 or more knuckles visible at address — which makes the face easier to close and is a common fix for a chronic slice.
- SliceA slice is a shot that curves sharply away from the target — to the right for a right-handed golfer. It happens when the clubface is open relative to the swing path at impact.
- Face AngleFace angle is where the clubface points at impact, relative to the target line, in degrees. It determines roughly 75–85% of the ball's starting direction.
- Grip PressureGrip pressure is how tightly the hands hold the club. Most instructors recommend a light-to-moderate pressure — enough to hold the club securely, loose enough to allow wrist hinge and a free release.
