After nearly 3 years, PXG finally launches new 0311 (T, P, XF, SGI and X) Gen2 irons



Almost three years after launching its first-generation 0311 irons (July 2015), Parsons Xtreme Golf (PXG) has finally announced its new 0311 Gen2 irons. And as with its initial launch, the company is making BOLD claims about the new irons. Overall, according to PXG, the new irons are longer, faster, produce higher launch angles, less spin, higher peak heights, steeper landing angles, have improved accuracy — in terms of both distance and dispersion — and have better turf interaction. That leaves two important questions:

  1. How?
  2. What took so long?!

As part of the premise behind even starting the company, PXG founder and billionaire Bob Parsons doesn’t want quick product cycles; as he says, he doesn’t want cost constraints or time constraints, he simply wants to make the best products on the market. And he says he didn’t want to come out with new irons until they were better than the first generation irons. The problem is, just weeks before the launch of the Gen2 irons, Parsons called the first-generation irons the “best irons in golf, and they have been since they were launched.” So how do you improve on “the best?”

When the Gen1 0311 irons launched, Parsons says he immediately put his engineers — former Ping engineers — Mike Nicolette and Brad Schweigert to work on crafting irons that are better. Parsons says after two years, they “went down many rabbit holes” looking for improvements, and Nicolette says he crafted 13 different iterations of irons searching for something better. Even with the help of a PhD from Duke University “on retainer,” Schweigert says the process of finding something better took more than two years.

The turning point for Nicolette and Schweigert was discovering a new material… one that had a much higher rebound speed.

If you remember the original 0311 irons, PXG designed its irons differently than any iron that came before it, and using a different material. The iron bodies were forged from S25C soft carbon steel, and the face inserts were “as thin as a credit card” and forged HT1770 maraging steel; but it was the TPE (thermoplastic elastomer) injection mold between the face and the body that separated PXG from other irons on the market. This TPE material allowed PXG engineers to construct thinner faces — and thus faster — yet still enhancing overall feel without losing durability, according to PXG.

Again, three years later, the secret behind PXG’s Gen2 irons is the material that’s being used behind the faces (pictured above). Schweigert and Nicolette discovered a new polymer — they’re keeping the recipe close to the chest, obviously — that’s being injected into the irons; they call it “COR2” technology.

The name COR2 relates to C.O.R. (coefficient of restitution), which is a measure of energy transfer between two objects. In the case of golf clubs, you want the highest C.O.R. possible, although the USGA limits it to 0.83 (the lowest being 0 and the highest being 1). PXG claims COR2, versus the core material of the Gen1 irons, is 20 percent faster (according to a “drop test”), leading to 1-2 mph faster ball speed across the face. Additionally, due to the physics of the COR2 technology, according to PXG, the Gen2 irons also produce a 40 percent tighter dispersion. As Schweigert explains in our interview with him and Nicolette, this means the ellipse of average shots hit all over the face is 40 percent tighter than that of the Gen1 irons, thus, a 40 percent tighter dispersion (this is explained around the 6-minute mark in the interview above).

Core materials aren’t the only things that have changed since generation one, however.

For higher ball speeds across the face, and an increased “functional face area,” PXG engineers extended out the face area supported by the COR2 material with an internal perimeter cutout. That means there’s more space behind the face to fill with COR2 polymer, resulting in a 15 percent larger hitting area.

Also, PXG is using new 8620 steel bodies in its 0311 Gen2 irons versus the S25C steel that it used in the original 0311 irons. In its press materials, PXG says “the yield strength of 8620 is more than twice as strong as S25C.” The result, according to PXG, is greater durability, while still maintaining “the club head’s soft forged feel.” The face insert material and thickness, on the other hand, has remained the same; the faces are still made from HT1770 maraging steel and measure about 1.5 mm.

For higher MOI (moment of inertia, a measure of forgiveness), PXG has angled the back surface of the clubs, tapering them from heel-to-toe. That means there is greater mass on the toe portion of the club. The topline, however, is also angled so that it appears to be parallel to the face. Ultimately, the result is a topline that looks a bit thinner, and a 3 percent increase of MOI overall, according to PXG. The camber on the soles of the clubs have also been reduced so that players can take slightly more turf at impact compared to the Gen1 irons, allowing them to hit it higher on the face, according to PXG. Nicolette and Schweigert explain how this works in our interview (around 5:40).

PXG also addressed a small concern from Gen1; dirt would get stuck in the numbers on the sole and the paint would wear. According to Parsons, the PXG team tried to find wear-proof paint, but ultimately, they simply moved the numbers out toward the toe so that it wouldn’t interact with the turf as much. Problem solved.

Looking at the overall line of 0311 Gen2 clubs, you’ll notice an increase in the number of offerings; there are now five. The Gen2 line includes 0311 T (Tour), 0311 P (Players), 0311 XF (Xtreme Forgiveness), 0311 SGI (Super game-improvement) and 0311 X (driving irons, 1-5 irons). According to Nicolette and Schweigert, the models have been designed with mixed sets in mind.

Starting on April 19, the Gen2 irons will sell for $400 per club in the standard finish, and $500 per club for the Xtreme Dark finish, which uses a black, diamond-like carbon coating, according to PXG. Among all of the flexes and steel/graphite options, there are 105 shaft offerings available in the standard irons, and 14 in the driving irons.

Read on for more information and specs on each of the iron offerings, and click here to see what GolfWRX Members are saying about the 0311 Gen2 irons.

PXG0311 T Gen2 irons

The T iron is “best suited for the player interested in maximum workability,” according to PXG, and for the player who prefers a more compact size. Compared to Gen1, the Gen2 T irons are reported to have less offset, a straighter leading edge appearance, less sole camber, trailing edge relief, a more rounded head profile and 2 percent higher MOI.

Tour players who have already made the switch include Billy Horschel (3, 5-PW), Charles Howell III (5-PW), Ryan Moore (5-PW), Charl Schwartzel (5-PW) and Ryann O’Toole (4-PW).

PXG 0311 P Gen2 irons

The P irons have moderate blade lengths and offset to satisfy the needs of a wide range of golfers, according to PXG, offering an “ideal balance of playability and forgiveness.” Compared to the Gen1 0311 irons, the o311 P Gen2 irons are reported to have a thinner topline appearance, less offset, a straighter leading edge, less sole camber, and 3 percent higher MOI.

The Tour pros who have these in the bag now include James Hahn (3 and 4 irons), Lydia Ko (5-PW), Anna Nordqvist (4 and 5), Katherine Kirk (5-PW), Christina Kim (4-PW), Brittany Lang (5-PW) and Alison Lee (5-PW).

PXG 0311 XF Gen2 irons

The PXG 0311 XF Gen2 iron, according to PXG, is a “game improvement club that offers extreme forgiveness and a superior feel, while maintaining the sleek look of a blade.” Compared to the T and P models, the XF irons have larger head sizes. Compared to the Gen1 XF irons, the Gen2 XF irons are reported to have a thinner topline appearance, more offset, less sole camber, and 3 percent higher MOI.

PXG 0311 SGI Gen2 irons

PXG’s first ever Super Game-Improvement (SGI) iron has a thick topline, a low profile and a wide sole to help golfers launch it higher and achieve maximum forgiveness. It also has a longer blade length than the other models and more offset to effectively help golfers turn the golf ball over.

PXG 0311 X Gen2 driving irons

PXG’s new 0311 X Gen2 driving irons are advertised as “low-spin” clubs that are designed “to deliver a more penetrating ball flight.” They’re available in irons 1-5, and have lofts ranging from 15-24 degrees. The lengths throughout the 0311 X Gen2 offerings are progressive — shorter in the higher lofts and longer in the lower lofts.

    I just bought the 0311T Gen2 irons and love them. Such a soft, solid feel on every shot. Better than my Mizuno MP 18’s.

    For most gearhead golfers 75% of the game is what you own, not how you play, and then bragging (lying) about how great your newest clubs are compared to your last set of status clubs. Delusion happens in the 6 inches between your ears.

    Hey,,,, if you are made of Money why not. Or maybe not made of Money but want to look like a Golfer with a big ego to be the first on the block to have them, why not. They may satisfy an ego, or a curiosity, but will they make you better than you are ?, nope. But if you want em, go get em and enjoy them.

    Most guys here shouldn’t comment on the clubs unless they have tried them! I have tried them and there is nothing that compares to them, expensive yes but you get what you get what you pay for. By the way, most pros get paid to use equipment, so they must like them to use them! Taylormade dropped Garcia and is still winning with similar clubs from call away!

    I’m really surprised that Zach Johnson , being the Iowan blue collar type, would play these Champagne type of sticks! Maybe these clubs are the reason for his fall from the clouds.

    Wow, that’s a lot of hate for really a great set of irons. I’ve got a set of the P790 and a set of the 0311t. The feel is better hands down in the 0311t. Also less offset and way less chunky in the mid short irons. I prefer the 0311t over the other player irons I’ve hit that include Titleist, Mizuno and Taylormade. They are very forgiving for a blade and long. I didn’t like the standard 0311 as to me it was just too big. If you’ve got the cash and want to play a great set of irons, I’d at least consider trying them. Also, I’d ignore the BS hate on the irons as they are solid sticks. If you don’t like Bob that’s fine, but the irons are top notch. Worth the extra cash? To me yes.

    So they went to 8620 steel just like the other companies but want to charge almost three times as much. The 790’s have proved you can make the same clubs for less.

      Exactly. Made of junk. And the originals were so well thought out and so well designed, the paint chipped off the numbers. So what did they do this time? Move the number to the toe, because the originals were so well designed. Nobody designs junk like Parsons and flog it for thousands to thousands of suckers

    $5k for irons that have a cheap 5 cent baby ferrule. Love the quality of their clubs just not a fan of that look.

      I may be wrong but I believe those are fitting heads and the ferrules on the standard clubs are full sized.

    I look at my WITB set of irons and I feel… impotent, after reading about the PXGs.
    Even though I can’t afford a full set I will get a partial set… 5/7/9/PW, and play with those and then add more clubs next year until I fill my bag. I wanna be a PXG playah for the pride and added mojo that I need.

      Just the other day, a guy was at my instructor’s range, and saw me hitting the 0311XF and asked about them. I handed him a 7i. He’d been hitting the Ping G700 irons. He hit the PXG and said, I like the look and feel of these over the 700’s. I took the G700, looked down at it, and it did not look good at address, did not feel as good, but nice ballflight.

      We both preferred the PXG 0311XF.

      Still, I’d try the Callaway Rogue Irons for distance and forgiveness.

    i’d actually be embarrassed with these in my bag. going out shooting 80 with sticks that cost 4 to 5 times what a brand new set of irons from equally good company…no thanks. not just because the cost, because of the image it gives off.

    They look slightly better in the back, but in the XF 3% more MOI, and more offset, is not attractive to me or enough of a change. Going to 8620 steel sounds like a way to save money. I see the price going to $500 per iron in satin and a better shaft. It’s a nice club, but if doing it again, I’d look at the Callaway Rogue.

All-new Srixon Q-Star: Spin where you want it!



If there is anything I have learned in the past year about golf balls, it’s that they are packed with more technology and chemical compounds than most people can comprehend. A lot of premium boundary-pushing technology is found in, as the name states, the premium ball category, BUT Srixon is bringing the same tech found is the Z-Star line to the masses with the fifth-generation Q-Star, priced at $26.99 a dozen.

So, what am I talking about when I say chemistry? How about Spin Skin with Slide-Ring Material (SeRM for Short). SeRM is a urethane coating with flexible molecular bonds (how many times do you think about molecular bonds when talking golf ball?). This flexible coating digs deep into grooves for more control and more stopping power.

When we say “control” we mean friction. Friction is extremely important in golf is because the more you can create with your scoring clubs, the more control you are going to have around the greens. Where does all this chemistry come from, you might ask? In case you didn’t already, know Srixon is owned by Sumitomo Rubber Industries — a world leader in rubber technology including tires. Hmm…I think if a company can find ways to increase friction on a tire on a car going 100+ MPH, there must be some type of parallel there…

When you consider that most average golfers miss a LOT of greens, and often times in the wrong places, having a ball that offers a bit more control than the standard two-piece ball means you can (hopefully) stop it closer to the hole. And if I’ve said it once, I’ve said it 1,000 times: The closer you golf ball end up to the intended target, the lower your scores are going to be.

Another way of getting the ball closer to the hole is distance, and the Q-Star isn’t lacking in that department either. By utilizing Fast Layer Core Technology, meaning the core is softer in the middle than around the outer layer [think of it like a symmetrical round muffin top (drool…mmm…muffins)], they can create a ball that is lower compression, feels great, and spins less off the driver without sacrificing the oh-so-important distance. Don’t forget that less spin off the driver ALSO means less axis tilt (often wrongly communicated as “side spin”) creating shots missed left and right.

All off this technology wrapped up in 338 dimples, available in both white and yellow.

Forum Thread of the Day: “What has made it into your bag so far in 2019?”



Today’s Forum Thread of the Day discusses new equipment that has made it into the bags of our members so far in 2019. From new club additions to shaft changes, our members share the tweaks they have made so far this year and divulge what has been successful as well as what has failed to work for them.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • Jackal66: “Went from 816 DBD Alpha driver to M3. Changed Odyssey Fang putter to Scotty Cameron Newport putter. Bought a 56° wedge and it is competing with my 53° Diadic.”
  • ObiwanForAll: “Gone all in with TaylorMade clubs and UST shafts.”
  • macedan: “Successes- Ping G400 9*, thought the smaller head size may hamper my confidence, but It has performed beautifully. Mizuno ST180 16*, No words, performs as needed and looks absolutely sharp. Middle of the road- Ping G Crossover 21*, unfortunately, I fell into a swing slump across the bag not long after buying it. When my swing is on, it is one of my absolute favorites in the bag. My biggest complaint is just the appearance of the massive amount of offset.”
  • pollock21: “Been quite a year…TS3 knocked out my trusty G400 LST which was quite a feat. Now shafted with 130 Rogue Silver. I500 w/LZ 7.0 125’s experiment is on the way out. They’ve been excellent irons for me, but I just hit them obnoxiously long. Currently looking for my next set. Also dabbling with a hi-toe 60 to replace my trusty 60* Glide 2.0 stealth. So far, I’m loving it. Last change was putting in the copper spider x which knocked out my ketcsh and scotty newport 2.0.  Failed experiment so far with the flash sz fairway. Putting the trusty 16M2 back in the bag. Definitely moving on from the flash, I’m just not as consistent with it.”
  • shanx: “Took a lesson late spring and my ballstriking has improved. I ditched the Callaway X20 Pros, Cally X Forged ’07s, added Mizzy MP15s with C Taper Lites. Not sure if those shafts will work for me in the long run, but I am going to play them for a bit as I am still working on swing changes from the lesson. Rotating three drivers (2 Titleists and a Callaway Epic), thinking about going to get fit for my driver soon.”
