Mizuno JPX 800 Iron Review

At first glance, it is apparent the Mizuno JPX 800 iron is designed as a game improvement club.  In fact, the JPX replaced the previous Mizuno MX line.  They utilize a thick top line with a triple cut sole designed to make the iron more playable from any lie.  The pocket cavity helps deliver the largest MOI of any Mizuno iron.  The chrome finish looks sharp with blue and black accents.  Mizuno designed the JPX with conforming U grooves.  Overall, the iron looks like a beautiful combination of a full-on cavity back with the sleekness of a players iron that is likely to appeal to wide variety of players.


I tested the Mizuno JPX 800 irons with a True Temper Dynalite Gold s300 shaft.  Mizuno claims they are geared toward a player with a handicap range of 8 to 30.  Similar to many other game improvement irons the JPX feature strong lofts, which generate additional distance.  The combination of the low COG and strong lofts really help the average player get a lot out of these irons – the JPX 800’s are some of the longest irons out there by my books.  Mizuno designed the JPX 800’s with a low and deep center of gravity.  As result, they produce a high ball flight which is great for a mid to high handicap player.  In addition, the clubs are extremely forgiving.  Off center hits still produced a high and straight trajectory.

The JPX 800’s provide some workability for better players who prefer to shape their shots.  Since the irons are designed to hit high and straight I had a difficult time controlling trajectory.  Essentially all of my shots went high and long, exactly how they are designed to perform.  Mizuno has other irons for the player looking to control the ball.  Overall, the JPX 800’s are one of the top performing game improvement irons out there in my opinion.


The Mizuno JPX 800 irons deliver a firm “crack” sound at impact.  Shots struck in the sweet spot feel very smooth.  The JPX 800 irons are extremely forgiving and still produce high and straight shots on off center hits such as the toe or heel.  Personally, I enjoyed the slightly heavier feel of theseirons.  Mizuno did a great job of designing a club that has fantastic feedback and is very easy to hit.


Mizuno has consistently made some of the top irons in the golf industry and they can now boast one of the top game improvement irons in their line up.  While the JPX 800 irons target a mid to high handicap player, low handicap players might still enjoy the easy to use them as well.  The  only thing un-Mizuno about the irons is the price – the JPX 800 has a competitive price of $699.99 for a set of eight irons.  If you’re in the market for a club that will help take your game to the next level, I would suggest giving these irons a shot.
