what is the make and model of the grips?
asked by R. v. S. on 6/27/2021
Unfortunately, due to the size of our inventory, we are unable to verify specific grips on a used set of clubs.

Beauty and the Beast

Handicap: 11-15  Plays Golf: I play monthly  Dexterity: Right Hand

This is my first experience with Mizuno irons. First of all these clubs are beautiful. The aesthetics are stunning and screams of great quality and craftsmanship. They are a beast on the course, long and strong. I love the black PX shafts in mine; makes these irons very powerful.

Handicap: 0-5  Plays Golf: I play weekly  Dexterity: Right Hand

I spent some time this year researching my new irons. I demo&aposd a bunch of different models and these were the best combination of looks and performance. They still look fairly small and don&apost have a huge amount of offset so they tick all the boxes for me and they flat out perform. The ball launches nice and high and distance is perfect. I did have to adjust a bit in terms of club/distance but that is primarily due to the loft of these being quite different from my last set.

Completely Satisfied

I got these Mizuno Hot Metal Pro irons in Certified Used condition for a great price. They arrived quickly and they are essentially brand new. The black shafts look awesome! I'm a pretty high handicapper but I wanted some decent clubs because I intend to start working on my game. I've played with them a few times now and the increased distance due to the adjusted lofts is obvious. They sound good, look good, and have improved my accuracy a bit already.

Technology / Specs

JPX 921 Hot Metal Pro Face

Chromoly 4140M Base Maximizes Speed

Now in its 3rd iteration, the re-imagined CORTECH face technology on the JPX 921 Hot Metal Pro irons has been stretched to its limit for maximum distance and speed, all while having a 0.2mm thinner center point.

JPX 921 Hot Metal Pro Sole

New Face Design for Smoother, More Solid Contact

The JPX 921 Hot Metal Pro irons were crafted with a new thickness and sole design, allowing the leading edge of the club to operate in a more hinge-like motion, producing more ball speed and flex in the face. The JPX 921 Hot Metal Pro irons were also specifically designed to have a tighter profile with reduced offset.

JPX 921 Hot Metal Pro Toe

New, More Stable Frame

With additional perimeter weighting, the new JPX 921 Hot Metal Pro irons have increased toe bias, further making off-center strikes more accurate.

JPX 921 Hot Metal Pro Sound

Crisp, Solid Sound

The JPX 921 Hot Metal Pro irons have been crafted with 3 additional vibration detecting ribs, producing a cleaner, more solid sound at impact.

JPX 921 Hot Metal Pro Finish

Brushed with a Pearl Finish

The pearl finish on the new JPX 921 Hot Metal Pro irons reduces glare at address, minimizing any distractions that may be seen when addressing the ball.
