PXG put zero torque into a blade putter instead of a mallet, and that is the whole story of the Mustang ZT. I got fitted for one and tested it, and I was blown away. It is PXG’s fourth zero torque putter and the first that looks like a traditional blade, which matters because the mallet shape is exactly what a lot of blade players refuse to put in the bag.
The specs tell you what kind of blade it is: 34 inches standard, 365 grams of stock head weight with 350 to 385 grams of adjustment, 4 degrees of loft and 70 degrees of lie, with a full shaft offset and a toe-up, zero torque hang. PXG calls the look a bold blade profile, and the weight you feel in your hands is the mass sitting out at the perimeter where it buys stability.
Quick Overview
- Zero Torque Design: the CG sits just below the shaft axis, so the face stays square to the path through the stroke.
- S-COR polymer-filled hollow body: bonds to the face, dampens harsh vibration and supports consistent launch and roll across the face.
- Milled Pyramid face pattern: third-generation aggressive milling, optimised for how the face interacts with ball dimples.
- Two adjustable sole weights: 365 grams stock, adjustable from 350 to 385 grams, shifting mass to the perimeter to raise MOI.
- Blade looks with zero torque behaviour, built in right and left-handed, and fitted for length, loft, lie, grip and weighting.
The Zero Torque Transformation
The S-hosel is where this putter earns its name. PXG orients the shaft axis just above the centre of gravity to create a toe-up balance point, and with the CG sitting just below that axis the putter minimises torque through the stroke rather than fighting it. The published effect is that the face stays square to the path, so there is less for you to manipulate. One detail worth having straight: that hosel sets your hands into a natural forward press, so PXG says it plays like a standard 3-degree loft configuration even though the spec sheet lists the head at 4 degrees.
What the hang angle tells you is that this is a toe-up putter with full shaft offset, not the mid-toe hang of a conventional plumber’s neck blade. That is the trade you are accepting for the zero torque behaviour, and it is why PXG recommends a fitting rather than a shelf pull: length, loft, lie, grip and the two sole weights all get set to your stroke in the same session.
Here is the honest version of what the technology is for. PXG’s claim is steadiness through impact, so you can think about the read instead of holding the face square, and that is the reason to go and roll one rather than read about it. I would get fitted and test it yourself before you buy.
The ZT is also the one that fixes the look problem. The original Mustang was not zero torque, and most zero-torque putters have arrived as mallets. This version adds PXG’s zero torque technology and the same pyramid face used across their zero torque line, in a larger, more forgiving blade shape, with the offset and grip options you would expect from a full PXG fitting.
Hollow Body Construction That Actually Delivers
The hollow body is what makes a blade this stable possible. PXG hollows the head and fills it with S-COR polymer, then pushes mass out to the perimeter with the two sole weights, and the published result is a higher moment of inertia for greater stability and forgiveness. That is a design claim about where the weight sits, not a promise about your misses.
The face is 0.055 inches thick, which PXG describes as mass-optimised for stability and feel: thinning the face frees weight to go where it does more good. That is the same idea as the adjustable weights, applied to the front of the head instead of the sole.
S-COR is the part you hear rather than see. It is a lightweight polymer injected into the hollow cavity that bonds to the face, dampens harsh vibration at impact and supports consistent launch and roll across the whole face. PXG’s own framing is the soft sound of an insert with the response of a solid milled head.
Forgiveness on a blade comes down to where the mass sits, and here it sits at the perimeter by design. PXG’s stated aim is consistency across all strike locations rather than a rescue on every mishit, and a fitting is where you find out what that does for your stroke on your greens.
The Pyramid Face Pattern Changes Everything
The Pyramid face is PXG’s third-generation pattern, and the aggressive milling is there for one job: how the face interacts with the dimples on the ball. PXG’s claim for it is a consistent roll with the soft sound of an insert and the response of a solid milled face, across the whole hitting area rather than just the middle. It is the same pyramid face PXG uses across their zero torque line, so if you have rolled one of the others you already know the sound.
The honest limit on all of this is that PXG publishes a design intent, not a roll measurement, and I have not put a number on it either. What the pattern is tuned for is the first few inches after impact, which is exactly where a putt either starts on your line or does not.
Sound is part of the design here rather than a side effect. PXG’s stated target for the pyramid face and the S-COR fill together is the soft sound of an insert with the feedback of a milled head, which is an unusual combination to aim for and the thing most people will notice first on a practice green.
Off-centre strikes still tell you where you hit it, because a milled face does that, but the polymer is there to take the sting out of the message. That is the balance PXG is trying to strike with S-COR: feedback without harshness.
Customization That Actually Matters
The adjustable weighting is the part you will actually use. Two sole weights take the head from its 365-gram stock setting down to 350 or up to 385 grams, and PXG’s stated reason is to shift mass to the perimeter and raise MOI for stability and forgiveness. A fitting is where that gets set, along with length, loft, lie and grip.
I had mine set up in a fitting rather than guessing at it, which is what I would do with any putter that ships with two weights in the sole. PXG’s own line is that a professional fitting optimises the setup so the launch conditions match your stroke, and the published head-weight range is 350 to 385 grams. The sensible order is to roll a few first, then spend.
The weights are the adjustment PXG publishes for this head, and they are the ones worth planning around. Length, loft, lie and grip are fitting choices too.
The ZT also comes with a slant grip built specifically for it, plus the offset and grip options you would expect from a full PXG fitting, and it is made in both right and left-handed. PXG fits it at their own locations, which is the route I would take with a zero torque putter you have never rolled.
Premium Feel at a Premium Price
This is a premium putter and it is priced like one, so the only question that matters is whether the feel justifies it for you. PXG publishes the price and it moves, which is why there is no figure fixed to it in this review.
The feel comes from three things working together: the 0.055-inch face, the S-COR polymer behind it and the pyramid milling on the front. PXG’s stated target is the soft sound of an insert with the response of a solid milled head, and that combination is the reason to roll one rather than take anyone’s word for it, mine included. If you want numbers for the rest of your game, a rangefinder does that job; a putter you have to feel.
Grip and shaft are fitting decisions on this putter rather than fixed parts of it: PXG fits length, loft, lie angle, grip and the adjustable weighting to your stroke, and the ZT ships with a slant grip built specifically for it. That is worth saying plainly, because the grip changes the feel more than most buyers expect.
What PXG does not publish is a temperature or durability figure for the S-COR fill, so I am not going to invent one. What is published is the job it does: bond to the face, dampen harsh vibration, support consistent launch and roll.

Frequently Asked Questions
Does PXG Offer Custom Shaft Options for the Mustang ZT Putter?
Shaft choice is not the Mustang ZT’s adjustment. What PXG fits on this putter is length, loft, lie angle, grip and the two adjustable sole weights, and the ZT comes with a slant grip built specifically for it. Whether a particular aftermarket shaft can go in this head is a build question for PXG’s fitter rather than something to assume from another model in the line.
What Does PXG’s Warranty Cover on the Mustang ZT Putter?
PXG publishes its warranty terms on its own site, and those terms are the authority for the putter you buy rather than anything a review states. Keep your proof of purchase from an authorised source, and warranty questions go to PXG directly.
Can I Trade in My Old Putter Toward the Mustang ZT?
PXG runs a trade-in route for clubs, and the current terms, the valuation and what they accept are published by PXG rather than by me. A quote taken before the order is what tells you the real cost of funding a Mustang ZT with an old putter.
Is the Mustang ZT Putter Available for Left-Handed Players?
Yes. PXG lists the Mustang ZT in right and left-handed, and the standard specification is the same either way: 34 inches, 365 grams stock, 4 degrees of loft, 70 degrees of lie, with the toe-up zero torque hang and full shaft offset.
What Grip Comes Standard With the Mustang ZT Putter?
The ZT comes with a slant grip built specifically for it, and grip is one of the things a PXG fitting sets along with length, loft, lie angle and the adjustable weighting. A specific grip model is a fitter question rather than a spec you read off a page.
Final Thoughts: PXG Mustang ZT Putter Review
The Mustang ZT is for the player who wants a blade at address and zero torque behaviour through the stroke. I got fitted for one and tested it, and I was blown away: if you like a blade but want zero torque consistency, this is the one to try. PXG’s own claim is steadiness through impact rather than a lower score, and that is the right way to read it.
Skip it if you are happy with your current gamer, or if you want the pure feel of a fully milled blade with no polymer behind the face. This is a premium purchase solving a specific problem, which is face control through the stroke, so I would get fitted and test it yourself before you buy.
