PXG's new Secret Weapon mini driver: what a 4.4% thinner face really changes

PXG unveiled the second-generation Secret Weapon mini driver on October 22, 2026. The company retained a 300cc clubhead and 13-degree loft but revised the face, internal sole structure and weight distribution. The release offers a useful look at the growing category between a full-size driver and a conventional 3-wood.

A thinner face is not automatically a longer drive

According to PXG, the face is 4.4% thinner than in the original Secret Weapon. The goal is to allow more deflection at impact and return energy to the ball. But a thinner face also raises structural demands. Engineers therefore redesigned the internal sole geometry to distribute impact stresses behind the hitting area. Weight saved in this process was moved towards the edges of the head to increase moment of inertia (MOI). A lightweight carbon crown helps move mass lower and farther back.

The manufacturer associates these changes with faster ball speed and tighter dispersion on off-centre strikes. Its announcement, however, does not contain an independent comparative test with a transparent methodology and full shot data. Any claim that every golfer will gain a particular number of yards would go beyond the available evidence.

The numbers that matter

The standard specification is 300cc head volume, 13° loft, 215g head mass and a 58.5° lie angle. Standard playing length is 43.25 inches, with right- and left-handed versions offered. PXG listed a US starting price of $499 at launch. For comparison, the previous Secret Weapon had a standard length of 43.75 inches. The new build is therefore half an inch shorter, potentially making consistent contact easier for some players, although the effect depends on their swing.

Four adjustable sole weights

There are four ports on the sole: front, back, heel and toe. The stock setup contains two 7.5g and two 2.5g weights. Switching their positions changes the mass distribution and can influence spin, trajectory, shot-shape bias and swing weight. An adjustable hosel also permits changes to loft and lie. These features should be evaluated across a group of shots rather than judged by the longest individual strike.

PXG positions Secret Weapon for use both off the tee and off the fairway. Yet a 13° loft and a 300cc head may be more difficult to launch from awkward turf lies than a traditional 3-wood. On a narrow par-4, on the other hand, the shorter shaft and compact head may offer an alternative to a full-size driver if that club produces excessive lateral dispersion.

Compare three clubs, not three marketing claims

A useful fitting would test Secret Weapon alongside the player's existing driver and 3-wood. Relevant figures include carry, total distance, spin, launch height and the percentage of shots finishing inside a chosen fairway width. For long second shots on par-5 holes, landing angle and how much the ball runs should also be assessed. A single standout strike is not evidence of a consistent advantage.

Bottom line. PXG has made real structural changes: a thinner face, reinforced sole, perimeter weighting and shorter standard length. The specifications are verified through the manufacturer, but the performance claims remain claims until tested for an individual golfer.
