Mizuno MX-300 Irons Review

About the MX-300

Mizuno has been churning out great forged clubs for years now and has earned a reputation for creating beautiful looking, soft feeling quality irons that retain their quality long after the hype has passed.

Over the last couple of years they have been releasing new models at a bewildering pace and golfers have never had such a wide range to choose from. As a basic rule of thumb, Mizuno entitles their classically designed mid to low-handicap clubs the MP irons and the MX series for mid to high handicappers.

But what about the MX-300 Irons? Although an “MX,” they’re not for the weekend or casual players; you need to be a decent ball-striker to get the best out of them as they aren’t hugely forgiving.

Single digit guys and girls may give them a whirl but are more likely to choose an MP iron for the added workability.

So although the Mizuno MX-300 could be in danger of having an identity crisis, Mizuno is confident that they fill a niche that lies between the shadowy boundaries of low and mid handicaps.

So if you sit around a 9 – 14 handicap then these are worth a look.

Looks and Features

The MX-300 is another strong Mizuno design. It has a small cavity back adorned with simple black and silver graphics and looks neat and classy. The topline is pretty thin but there’s a bit of width there to stop your teeth chattering as you address it. It looks like just what it is, an iron that isn’t quite a blade or muscleback nor a chunky game improvement iron.

The lofts are strong for distance junkies but the head contains Mizuno’s Y-Tune technology that helps lessen the drop off in performance from toe end hits. You can see from the picture how that Y shaped bar runs across the back of the club and separates into the arms of the Y toward the toe. All very discreetly of course, this is Mizuno we are talking about.

So is it the best of both worlds or a bit of a lost soul? Only one way to find out and the range was calling…..


Well they do look good. In the hand they feel like a proper iron should and the looks are elegant and professional. The weighting is nicely balanced; you can feel the club head but it is not like you are trying swing a sledge hammer around. All in all it the usual Mizuno quality on basic looks and feel.

Now I fit right in when it comes to the type of player that Mizuno are aiming the MX-300s at. Blades are a slightly distant dream but I want a little more finesse than a wide soled game improver. These look just the ticket. They have a slim top line, beautifully proportioned head size and a drop dead gorgeous chrome finish.

It’s there. No doubt about it, it’s there. That wonderful buttery soft Mizuno feel makes the MX-300s a pleasure to hit. It just leaps out at you as soon you make contact. Pure silk forged heaven in a crystal glass, served by your favorite barkeep. I could go on for hours about the feel…I really could but I guess you want to know a bit more than that so let’s move on. If you haven’t got the message by now you never will.

The MX-300s are long due to their lofts and the flight is very strong and penetrating. I found my best shots flew very much like a blade, soaring to the top of its flight and then parachuting gently down onto the target. A real dream and great for zeroing in on the green.

Off center strikes were punished but not severely. You weren’t strapped across the desk and given a good flogging, just made to empty the trash and given some extra homework. My bad shots flew O.K. and still felt fine although the special feel was gone; these aren’t great strikes after all. I’d say I lost around 10-15% distance which beats a lame dribble up the fairway by a long shot.

Whilst they offer some help on the less than perfect shots they aren’t really for the most casual players or beginners. You do need a bit of experience and ball striking ability to make the most of them. It seemed to me that the niche Mizuno are looking at satisfying with these was perfectly identified.

The long irons naturally have a little more help and I was happy enough with how I hit the 3, 4 & 5 irons. The good ones really stay hit and fly true and high. Lower down the set, the “helpful” nature of the clubs tails off and you’re given a short irons designed for shaping shorts, ideal for finding nasty pin locations or avoiding trouble.


The Mizuno MX-300 irons do their job very well. It provides playability, enough forgiveness for a proficient but not stellar iron player and a feel to die for. Few cavity backed irons have that level of purity in the strike and even fewer make you want to go and buy another basket of balls and carry on hitting them but that’s what I did.

It’s a competitive market in the low-mid handicap zone but if you fall into that category than the MX-300 is a must try.
