The Srixon Z 355 irons are easy to hit long, high, and straight.  Fantastic sole design.  Heavy head.

Just like the Z 355 driver, the Srixon Z 355 irons are bringing a unique story to the market: heavier is better.  Through heavier heads and counter balancing, these irons promise greater distance and more consistency.  Additionally, they have one of the best soles you’ll find on a game improvement iron.

From address, the Srixon Z 355 irons give you exactly what you’d expect from a game improvement iron.  The head is average in size, and the top line is neither thick nor razor thin.  There is quite a bit of offset, particularly in the longer irons.

In the bag, the Z 355 is a sharp looking club.  The head is primarily chrome, but there’s a ribbon of sparkly matte finish that creates a unique look.  The limited branding makes it cleaner looking than many GI clubs, but the splash of red in the cavity keeps it from being dull.

Sound & Feel

Like the other Z 355 clubs, the first thing you notice when you pick up the Srixon Z 355 irons is the weight of the head – it’s heavy.  This gives you a great sense of where the club is during the swing.

When you get to impact, the Z 355s feel firm with a great, crisp sound.  Mishits don’t feel drastically different than pure shots, but they do lack a certain sweetness that you get from flushing one.

From the first ball I hit, the Srixon Z 355 irons made a clear statement: we are long.  From the wedges through the long irons, the Z 355s are easily 10 yards longer than my current gamers.  Some of this distance is the result of strong lofts, but part of it has to be attributed to the Action Mass technology.  As with the other clubs in the Z 355 line up, the heads of these irons are heavier, and they’re paired with a light, counter balanced shaft.  The result is a club that feels easy to swing but hits like a sledge hammer.

While the eye-popping distance is what will get most golfers to open their wallets, the sole design is what really impressed me.  Srixon calls it the Tour V.T. Sole.  In short, though the sole is large to provide stability and lower the center of gravity, only a small portion of it comes into contact with the turf.  You can easily see the dramatic toe and heel relief in the picture below, and the trailing edge is similarly ground.  What this means for you is that these irons have the versatility to handle any lie but with the forgiveness of a game improvement iron.

This fall, the OEMs have released an avalanche of new gear, and there’s no shortage of hype around the “industry leaders.”  Though they aren’t setting the forums on fire with chatter, the Srixon Z 355 irons are likely to drop a few jaws when golfers get them on the launch monitor or the range.  If you want to hit your irons longer, the Z 355 is a must try.

  1. Matt,

    How would you compare the Z 355 irons to the Z 545 irons?


  2. Hi these irons can be compared with ap1 in Forgiveness? Or are more player iron?

    • Matt Saternus

      I haven’t tested the AP1 extensively, but I would say that they’re roughly in the same class if not a bit more forgiving.



  3. Did you feel the z355 irons did anything to stabilize your swing pattern for better ball striking as is marketed with the action mass? Or simply put, does the club do more for you than you do for it?

    • Matt Saternus


      I do think there’s something to be said for the heavier head in terms of distance and forgiveness, but I’m not sure what’s meant by “stabilize my swing.” The club can’t swing itself.


      • For stock clubs do you think it provided a more consistent swing path because of the weight, in effect reducing any chance you would swing to steep or to flat digging the heel or toe?

        • Matt Saternus


          Everyone’s swing is much more consistent than they realize in terms of path. Personally, I’ve never felt counterweighting provided a great benefit for consistency, but obviously there are many golfers who benefit tremendously.



          • How would you compare the miyazaki jinsoku shafts to recoil 680, which I’m familiar with? What is your general impression of the shafts availble: which provides the flatter trajectory? Do these clubs compare favorably with the Ping G and Titleist AP1, or are they more a SGI? Thanks!

          • Darold,

            I’m not a particular fan of the AP1. I think the Z 355 and PING G are in the same conversation and both deserve to be tested in a fitting.

            I haven’t used the Jinsoku iron shaft.

    I purchased these clubs recently. I play off 18 and have a slow swing speed 80 mph. Only had 6 hours on the range at present but I must say ACTION MASS works for me. The 3 wood is the most powerfull one I have hit. Club head weight and balance points on the light shafts felt right for my swingspeed from the first swing. Cant comment on the VT sole till I get on the course over Christmas. Will update you on that later.

  5. I just got them Saturday and with no range time played Sunday. I cant believe how nice I hit these irons. At least a club longer but the height of the ball flight is amazing with a soft landing on the greens. You can feel the club head through the bottom of the swing. I think with some practice this will help with the tempo of my swing.
    For the first time that I can remember I hit a nice 4 iron shot. I was never able to hit a good shot with my old set.
    I replaced an old set of Ram FX pro set irons that I bought around 1996.

    Thanks for all your informative work, I have recommended your website
    for anyone looking for an honest review of golf stuff.

    I recently purchased the Srixon 355 irons. I must say that with all the hype for lighter and faster from the major companies, these 355’s are like an old friend. What a pleasure to hit and results to match. I can feel the head all through the swing.
    I just turned 71 and I still play to about a 13. Your review of the 355’s was right on. Thanks again

  7. Great review, thank you for helping me find my “SOLEmate”. I bought a set a couple weeks ago and absolutely love these irons. I started playing golf again over a year ago, after 7 years away from the game. I have since tested dozens of different irons designs including (ping- I and G, Titleist – ap1-ap2, Callaway Apex and steelhead, Mizuno – mp54 ez forged 850 forged, ect). In the past I would keep two sets of irons, one “game improvement” and a set “players irons”. Often I would play with a mixed set. These irons are forgiving but have a nice clean look, reasonable size, and minimal offset. The v sole design combined with the heavy head and back weighting fits my swing perfectly ( my swing is more about leverage than speed, -high smash factor/accuracy). For me the z355s outperform much more expensive and well publicized competition.

  8. Hello,
    I assume you were testing a set of Reg. steel Flex? I wonder what the Reg. Flex in Graphite, would perform? The review was nice and went ahead and purchased a used, “Very Good,” set and will arrive 10/12/18. I will be replacing the factory grips with Mid. Size Golf Pride Velvet. I could find the A [Senior], but to much money, when shopping the other day and hard to find, being 3 years later after introduction. All independent reviews seemed most positive for 16 handicapper at age 75. My son wanted and bought my Wilson Staff Forged M3, reg steel shaft. He is a 7 handicap. Those W/S forged irons were so well balanced with Mid size grips, that it was like swinging a feather. These Z355’s, will see how they are balanced with Mid size grips.

  9. Follow-up Purchase:
    The grips were replaced with Mid Size, Golf Pride Tour Velvet, with 2 wraps of tape. This practically new set of irons with Graphite Std Flex, even though a 2015 model, a C9 or D1 swing weight, is my preference. I am able to produce a nice tempo with these 4 thru PW irons, having SOLID contact.

    Even though it is winter in Wisconsin, I play in an indoor winter golf league, using simulator conditions. I am MOST happy with these 3 year old model designed irons! The independent reviews drew me to these irons along with being in my price range. As a senior golfer, these Srixon Z 355 Graphite irons are consistent, using Titleist’s Velocity 2 piece ball.

  10. Got mine last week, 5-pw stiff iron shaft. Replaces other distance irons, Cleveland CG16. The z355s are a little longer despite the shorter shafts. Very nice feel, nice sole and much better looking with thinner topline. Hit 4 GIRs over 9 holes, great for me!
    Didn’t misstrike that many but a toe shot felt quite hars, went shorter and right, contrary I guess to what is said above. But I am glad it does that: will make me more careful with my swing while still playing a forgiving and long iron.

    Happy with my purchase which was based on this and other reviews. Cheers.
