New PXG Gen 4


PXG’s signature feature on its top-end irons has always been black tungsten screws. Highly visible, decidedly unique, and functional as well. Those unmistakable screws are still present in PXG’s newest GEN4 irons, but the most distinguishing feature of the new line is an even larger weight located in the center of the back of the club head.


So, what exactly is it for?

“This is an easy way to experience head mass,” PXG Chief Product Officer Brad Schweigert explains. “For the first time, we’re bringing to the fitting tee a really simple and efficient way to adjust the head mass up and down.”

The irons, priced at $349 per club, are available for pre-sale today at PXG’s website along with the rest of the GEN4 lineup. Deliveries are set for early April.


All of PXG’s new club sales entail a fitting process to ensure peak personal performance. The new weight, which is positioned near the center of gravity, gives customers a chance to try both heavier and lighter head configurations. While this variation isn’t uncommon at the professional level, almost everyone at the consumer level is playing the same head mass. (The obvious exception being those gearheads who know how to effectively use lead tape)

“This is something that we think is something that’s a game-changer for the marketplace and really hasn’t been done before,” says Schweigert.

Just don’t think of it like an adjustable weight on a driver, however. PXG’s new “precision weighting system,” isn’t intended to be adjusted by consumers. With a tamperproof screw head, its locked in place and can only be replaced by a PXG fitter.


When customers go to a fitting for the new GEN4 irons, virtually every club will come with a standard 8-gram weight. There will be occasional variations to counteract tolerancing in the head, shaft or grip and ensure swing weights are uniform throughout the set, but the standard is 8 grams. PXG’s fitters will have 4, 6, 10, 12 and 14-gram weights available as well, but they’re instructed to err on the heavier side. If players aren’t gaining swing speed by going lighter, they’re suggested to stay with a heavier head mass because it will generate more forgiveness.

Schweigert, who played competitively in college, says he and fellow PXG designer Mike Nicolette have typically played the same specs in their clubs – at least until they developed this technology and went through the testing of different head masses themselves.

Nicolette, 64, a former PGA TOUR player who won at Bay Hill in 1983, benefitted from going a little lighter and picked up some speed. On the flip side, the 43-year-old Schweigert saw gains from going slightly heavier.

“So, you have two guys who worked their whole career in product design and both of us were pretty much playing the same head mass,” Schweigert said. “If it can help us, who have been in and around this industry forever, it’s really going to benefit consumers.”
