Has anyone noticed that the mizuno irons have a heavy SW? My Mp32s seem to be quite heavy compared to my old macs and other irons i hit. It doesnt really worry me, but i seem to be able to swing the other irons much harder due to the lower weight. Can i reduce the SW at all?

Is it because they’re half an inch longer thus adding a couple of SW points?
Sure you can reduce the sw in a number of ways:
A: Use a heavier grip or put some lead tape under the butt of the grip ala Nicklaus.
B: Cut the shafts down.
C: Change to a lighter shaft.

If you still have you old clubs & a gram scale (or a friendly post office worker) compare the lengths & then the static weight of your 6 irons. Let us know what you find.

Yeah but my old irons are 1/2 over also. All mizzy irons iv picked up have the heavier feel to them. Is it just me? But a few people who have swung my clubs have picked up on the heavy SW.

Just weighed my macgregor forged cavs (rifle flighted lite, same grips and papers) against mizzy 6 iron with DG S300

MP32 6 iron: 456 grams

MAc M685 6 iron: 429 gram

Is it the shaft making it feel heavier maybe?

Half inch over what mate? Iron lengths have been creeping for years. Are they the same length side by side?

It’s wierd about the weight. You would think it’s the shaft as the heads should be within a couple of grams & Mizzy do tip weight their irons to achieve close sw tolerances.

The S300 comes in at around 130gm uncut & the flighted light is not 27 gm heavier (nor on Mizunos shaft list) I can guarantee you.

However Mizuno do knock out different head weight irons through their custom fitting program so it’s possible they are the heavy heads instead of a lighter set on a longer taper shaft bringing the weight up I think an email to Mizuno is in order to ask WTF….

Or pull the head son your six irons & weigh them…

Did you buy them new or second hand?

I bought them basically brand new from 3balls golf in the USA. They are 1/2” over whatever is standard mizuno length.

Yes but are they the same length as your other irons?

All three of my Mizuno Wedges SW at D5-D6 standard.

They all seem to be 36 1/4”

Yes side by side they are the same length.

Got my 6 iron checked today, D3 swingweight. I think the s300 shaft may make it feel heavier for me.

Chris,

there is a bit of a thoery that some people feel total weight more, and others feel swing weight more.

You might feel total weight a little more.

D3 is not head heavy by any means.

yeah its definately heavier, but it doesnt really worry me. I hit them well, so thats all that matters.
