There is nothing like the instant improvement you see in your golf game when you put a new set of irons in your bag.
Sometimes that improvement can last a couple of rounds, or other times it can last a couple of years! As players, we are all searching for the latter, but that even includes the manufacturers.
TaylorMade has been at the forefront in technology as it pertains to their M series drivers and we've seen those advancements trickle down to their various new designs in irons as well.
While the P 700 series irons have been designed with better players in mind, the M series has the mid-to-high handicapper or golfers who are seeking to generate additional distance consistently with their approach shots.
TaylorMade M3 Irons Review
The M3 Irons are strong in this department. The somewhat strong lofts combined with the RibCOR technology create a perfect formula for maximum ball speed.
Probably not the first feature that comes to mind when you try these M3s but when the ball is flying high and true and landing on the green more consistently, straight iron shots are just fine.
The thin topline gives the M3 Irons a players club feel. A low handicapper can look down at these beauties and feel confident and well-struck iron shot will follow.
But with all that being said, it still does not posess the beauty of a muscle back blade.
Excellent soft feel here. Nothing clunky at all for an iron designed for this type of player, thanks again to the RibCOR technology.
If you are shopping this club and want more feel, look at the P790s.
The biggest difference between the M3 Irons and the previous M models is what TaylorMade describes as RibCOR technology. With the goal of longer, higher and straighter shots in mind (and boy, doesn't that sound appealing?), the RibCOR channels energy to a localized point.
In essence, it stiffens the outside of the clubface to increase the face flexibility, which increases ball speed and promotes more accurate shots. Another bonus of the RibCOR technology is it softens the vibration at impact which improves the sound and feel.
Speed Pocket Technology transfers more energy to the bottom of the club where many players mishit their iron shots.
TaylorMade was innovative - although PXG may beg to differ - when it unveiled this improvement on its P790 irons which hit the market late in 2017. While those irons are geared to low handicap golfers, the M3s deliver for the golfer who may find the sweet spot less frequently.
The Face Slots enhance misses on the heel and toe.
The 15-gram tungsten weight optimizes center of gravity launch for optimal launch and stability.
The topline has been refined to please the better player's eye.
Here are the specs: The 5-iron is 37.75 inches with a loft of 23 degrees. The clubs, which are available 3 through Pitching Wedge, have a D2 swingweight.
True Temper XP100 is the stock steel shaft and Mitsubishi Tensei is the standard graphite shaft although various upgrades and options are available.
TaylorMade M4 Irons Review
These irons were designed to be the longest in the TaylorMade family. The company made the standard shafts approximately a half-inch longer and jacked up the 5-iron loft to 21.5 degrees (didn't that used to be the loft of a 3-iron or comparable hybrid).
Anyway, the numbers on the soles are only a suggestion in the modern world of iron design. The golfers who doesn't have the requisite clubhead speed to hit irons as far as he or she may like will love these irons. So will the Macho Men who love telling their buddies after the round they hit a 9-iron from 150 yards on a certain hole.
In the TaylorMade family, the M4 irons are probably the least workable on the market.
But that's not why you are buying these. Again, these were designed with speed and power in mind.
Although the M4 Irons are geared toward the higher handicapper, a lower handicap golfer who has the need for speed shouldn't have any problem looking down at these babies and feeling good when they pull the trigger.
The RibCOR technology is the secret here, dampening the blow, especially on off-center hits, to provide a soft, smooth feel for every club in the bag. But again, you are not buying these clubs for feel.
Just like the M3 Irons, the M4 irons are built with RibCOR technology, the face slots and speed pockets. They also have a slightly off-center sweet spot.
The fluted hosel design and extremely thin topline are upgrades on the M2 Irons, which is the iron this model replaces for Taylor Made. The manufacturer also claims the M4 Irons have a Moment Of Inertia (MOI) that's approximately 24 percent higher than the M2 model.
Here are the specs: The loft on the 5-iron is 21.5 degrees and the length is 38.25 inches. The swingweight is D2 with steel shafts and D0/D1 with graphite shafts.
M4 irons will be available in 4-LW with a choice of KBS MAX steel shafts and Fujikura Atmos graphite shafts.
Should I pick the M3 iron or M4 iron?
If you're a mid handicapper shopping between these two clubs, looking to squeeze a few more yards out of your iron shots, then the M3 Irons are the right selection for you. They're not crazy long, and there's enough feedback on off-center hits to be satisfactory.
If you're a power-hungry golfer with a higher handicap, the M4 Irons might be not only the best club in the TaylorMade family, but also as appealing as any of the speed-first irons currently on the market.
The bottom line is TaylorMade has put a product you can trust on the shelves for decades and truly has been ahead-of-the-curve in recent years, finding the ideal balance between aesthetics and feel while maximizing distance, launch and control.

Beginners & High Handicaps
Let me make one suggestion as you compare the irons above. Think really long and hard about ordering the 3 iron or even the 4 iron that comes with each set.
Although TaylorMade makes those irons easier to hit than years ago, you really should think about choosing a hybrid or rescue as TaylorMade calls them. You can read our review of the M3 Hybrid & M4 Hybrid here.
How do the M3 and M4 irons compare to other Irons on the market?
If you like your M1 Irons, the M3 Irons are your new club. Chances are you'll love how they feel and will be impressed with the slight improvements to aesthetics and feel.
If the M2 Irons suited your game, then grab the M4 Irons and you might just start hitting 7-irons from the same spot where you were hitting 6-irons before.
What about if you are new to the TaylorMade family or open to selecting a different brand?
Also, if you've been a Ping G series golfer in the past, you'd be smart to give these new Taylor Made M3s a long, hard look.
To get a deeper comparison of where these two irons rank, check out our guide to the best golf irons of 2018. In that comparison, the M3 irons belong to the game-enhancement category while the M4 irons are in the game improvement category.
If you are an absolute beginner or high handicap that is not improving, I encourage you to read our guide to the best irons for beginners or high handicaps. If you fall into this category and want a TaylorMade iron, our full review of the TaylorMade M CGB Irons is a must read.
The Bottom Line
From the introduction of the Taylor Made Burner and Burner Plus drivers in the 1980s to the various drivers and irons (and even golf balls) offered today, Taylor Made has been a industry name trusted by golfers of all levels.
The M series simply continues the trend. Finding new ways to make irons more forgiving and faster while not creating a club that is aesthetically pleasing is a tricky combination.
But TaylorMade has proven its unafraid to take chances and can handle the challenge with aplomb.
The TaylorMade M3 Irons and M4 Irons are just the latest indicators that advancing technology fueled by a strong research and development department continues to be the driving force behind the company's iron models.
