Mizuno’s Signature and Modern Series irons: Which iron should you be playing?
The iron line from Mizuno Golf has recently evolved to maximize its offerings for golfers of all levels. This new Mizuno Pro Modern series sits between the classic Mizuno Pro Signature Series and the technology-packed Mizuno JPX925 lines. Mizuno engineers took some DNA from each side to create the Pro M-13 and Pro M-15 irons, so you can get a lot of everything without compromise!
When you look at the refreshed Mizuno iron line, the Pro Signature Series is made up of the S-1 and S-3 irons that show off the traditional side of Mizuno iron creation. Both models are designed and crafted for feel and precision with shot makers in mind. Players who cherish that classic Mizuno forged feel with love the feeling of being more connected to the iron for impact feedback and precise ball control. Shaping and consistency from shot to shot are what the Mizuno Pro Signature Series does so well, like a finely tuned sports car on the track.

Mizuno took the traditions from the Pro Signature Series and added a good dose of performance to create the new Pro Modern Series with the M-13 and M-15 irons. Golfers will get, as they expect, the soft, forged feel that Mizuno’s Grainflow Forged HD process provides, but will also experience a more distance-driven design. Both the Mizuno Pro M-13 and M-15 will offer higher flight, more forgiveness, and, of course, more ball speed. Mizuno used multi-piece designs to create thinner faces and move weight in the head for added performance and stability. These more progressive irons combine that traditional feel and look with technology packed under the hood to fit a wide range of golfers.

Distance
Both the Pro M-13 and Pro M-15 are engineered with distance in mind. The M-15 is, of course, the leader in this group for ball speed and distance, thanks to its Contoured Ellipse face with Cortech technology. This multi-thickness face not only increases ball speed but keeps that speed consistent and removes hot spots from the face. Players will continue to maintain control of their shots while hitting less club into the greens. With the M-13, Mizuno engineers also used Contour Ellipse technology on a face that is 35 percent thinner than the Pro 243 irons. The M-13 delivers a great feel and responsiveness while producing a faster ball speed. Players looking to improve their length while maintaining control over their shots will gravitate toward the Pro M-13.

Forgiveness
When you pick up the Pro M-13, you appreciate the classic Mizuno shaping and compact look, but you don’t think it will be as easy to hit as it is. Off-center shots retain more ball speed than you would expect from a players looking iron. This consistent speed will allow you to still get the ball on the green when you don’t make perfect contact. Mizuno’s use of a Pocket Cavity in the long irons (4-5) and a Micro-Slot cavity in the mid irons (6-8) gives the set a lot of playability and precision. I figured the Pro M-15 was going to be an easy iron to hit, and I was not disappointed at all. A Multi-Material Hollow Construction in the longer irons (4-8) combines heavy tungsten weighting for optimal launch and stability. You can make contact farther out on the toe or near the heel and still see a shot with good launch and very little curve to it. Like the M-13, you can expect consistent ball speed across the entire face that will help you hit more greens.

Sound & Feel
When you hit a Mizuno iron, you expect a level of feel and sound that is pleasing to your senses. Both of these irons embody the attention to detail that Mizuno has demonstrated over decades of clubmaking. Both irons are soft due to the Grain Flow Forging process and offer a solid sound at impact. The Pro M-13 is a touch softer to my hands, but not by much, and I think most players who have hit distance irons will be impressed with how good these are. Even misses that are out in the toe or low on the face don’t generate harsh sounds or feel in your hands and ears. Solid strikes give you that swoosh and thud that make you love golf and playing forged irons.

Neal Shipley, AKA, the “Big Fridge’s,” custom stamping
Neal Shipley was the first to admit that he enjoyed his food while in college. But since his days at Ohio State, he’s slimmed down and earned a PGA Tour Card.
That hasn’t stopped him from having fun with his wedge stampings, though it’s led to some misunderstandings.
On the 54 (degree), we have ‘Big Fudge,'” Shipley told GolfWRX. “It was supposed to be ‘Big Fridge,’ so this happened a little while ago. ‘Big Fridge’ was a nickname between my college teammates and I, with ‘fridge’ meaning stomach, a big stomach.

“We told the Ping guys to put … ‘Big Fridge’ on it, and I think maybe some bad cell service or something, and they thought I said ‘fudge,’ so they put fudge on it.”
On Shipley’s 50-degree he also continues the food theme, this time with his go-to order at the “Golden Arches,” and his stamping “DONS 7.”
“The number 7 meal, the two cheeseburger meal, that was my McDonald’s order, back when I would have McDonald’s frequently,” Shipley shared.

Bought a set of untouched MP 241’s. What a great iron!!
Story is no one could hit them so they sat on the rack for over a year because hackers wanted to hit a 7 iron 225 yards. More corporate marketing BS.
Let’s look at the numbers Sap. The new P2790’s are now 25 yards longer! And made in China!! $$$

They need to loose the cursive logo and bring back the MP or just the symbol. Makes them look cheap

I think Miz has lost the plot by trying to emulate others and also trying to catch up to them. They should stick to making traditional lofted MB and CB like we all used to love. Too many cooks at Mizuno have diluted the Mizuno PRO idea. You have JPX, why the S and MS? So confused. Give us the MPs and stick to making slick blades
