A different engineering proposition, not a promise of fewer putts
On 1 November 2026, South Korean manufacturer WMX Grips announced Hole Loga, a putter grip scheduled to become available through its US channels on 2 November. Rather than relying solely on a flexible multilayer body, the design uses a rigid magnesium frame underneath a thin outer material. An optional system of removable weight segments is intended to let a fitter change the grip’s balance after installation.
These are manufacturer specifications, not independently demonstrated gains in putting performance. There is no published controlled trial showing that this grip lowers scores, improves start line or makes distance control more consistent.
Three weights, plus a modular counterweight system
The three reported base sizes and masses are Small 76 g, Medium 88 g and Large 100 g, excluding optional weights. WMX combines a pistol-style upper profile with a more parallel shape for the lower hand. Shape is a fitting choice; it should not be confused with the putter head’s loft, lie angle or face-balance characteristics.
A separate Performance Tuning Weight Kit contains modular 3 g, 10 g and 15 g sections. These can be screwed together and redistributed toward the butt end or farther down inside the grip. WMX says they can be rearranged after fitting, and recommends professional installation because of the magnesium structure.
Why mass location matters
Counterweighting alters the way the golfer perceives the putter’s head and may change hand action and stroke tempo. Adding weight at the grip end does not directly alter the head’s moment of inertia, nor does it change loft or lie angle. Players respond differently depending on putter length, head mass, posture, grip technique and stroke pattern.
The engineering proposition is that the stiff frame and movable internal mass can be tuned separately: one influences the grip’s structure and potentially feel at impact; the other adjusts overall club balance. Whether those perceived differences translate to measurable putting improvements remains unknown.
Not the first weighted or metal-bearing grip
Existing approaches provide useful context. SuperStroke CounterCore has offered interchangeable counterweights, while Evnroll Gravity Grip incorporated a metal element and attracted independent evaluation by MyGolfSpy. Accordingly, calling Hole Loga the first weighted or metal-based putter grip would be inaccurate. Its distinctive claimed combination is a magnesium support frame plus reconfigurable mass distribution.
There is also a timeline caveat. Korean retail listings using the HOLE-LOGA name predate this US announcement. Without a documented technical comparison of versions, the November release should not be portrayed as the first appearance of the name worldwide.
What testing is still needed
Serious assessment would measure consistency of manufactured weight, the durability of threaded modules, how the surface behaves with moisture, and repeatable putting results with the same head and shaft. A useful independent study would report start direction, pace dispersion, tempo and player-to-player variation—not only perceived feel.
Editorial assessment: the concept is technically noteworthy, but the launch does not establish a performance advantage. 2 November is the manufacturer’s announced US availability date, not a guarantee of stock at every retailer.
