          Mizuno Pro 243 Steel Golf Irons

          • Authorised Retailer
          • Free UK Delivery*
          • Full Manufacturer Warranty 

          The Mizuno Pro 243 is a more compact and precise iron than its predecessor, but it has gained speed across the face and provides a more satisfying feel at impact. It's a fantastic option for golfers seeking the tour-inspired, compact head design and appearance at address, with more technology to improve ball speeds and stability. Using their tried-and-tested copper underlay and Grain Flow Forging process from Mizuno's exclusive forging plant in Hiroshima, Japan, has allowed for the refinements and developments visible in the 243 model without sacrificing the key elements that have made this compact Mizuno cavity back iron so popular.

          Key Features & Benefits

          • Harmonic Impact Technology - This helps Mizuno engineers closely match the vibration patterns of their iconic muscle back irons to deliver the same soft feel they are renowned for.
          • 4120 Chromoly with Flow Microslot (4-7 iron) - A wider micro-slot maintains ball speeds across a larger clubface area, contributing to a more forgiving launch in the long irons.
          • 1025E Pure Select Mild Carbon Steel (8-GW) - As featured throughout the 241 irons, this provides the ultimate feel and control where needed most. Modern lofts have been used to maintain even distance gaps through the set.
          • Increased Bounce Angles - An extra degree of bounce in the long irons and 2 degrees in the scoring irons encourages an improved turf interaction through impact.
          • Wrap-Around Sole Grind - Heavy relief around the sole improves turf interaction and provides a seamless transition from the micro slot found in the long irons down to the 7-iron into the more traditional construction from 8-iron downwards.
          • Compact Players Profile - The set's thinner topline and reduced blade length throughout provide a fantastic, tour-inspired look at address.
          • Full Satin Brush - A less reflective finish with a more modern appearance.
          • Grain Flow Forged HD in Hiroshima, Japan - The 243 irons go through their Grain Flow Forged process, starting as a single billet, at the same exclusive Mizuno iron facility where their irons have been produced since 1968.
          • Soft Copper Underlay - A microlayer of copper beneath Nickel Chrome enhances the feel of Mizuno's Grain Flow Forged heads.

          At the Golf Shop Online, we offer a range of custom options and our 60-Day Play Better Promise so you can buy with confidence, and if you’re not completely satisfied, we can take your new clubs back!

          About Us

          Welcome to The Golf Shop Online. Since 2002, we’ve been helping golfers of all levels find the right equipment at the right price, with the service and support you’d expect from a trusted specialist.

          We started with a small pro shop and quickly realised that space limited what we could offer our customers. Moving online allowed us to showcase a much wider range of golf products from the game’s leading brands, all backed by professional advice and reliable service.

          Today, The Golf Shop Online is a well-established and respected retailer with thousands of happy customers. We are proud to be authorised by every brand we stock, which means every product you buy is 100% genuine and comes with the full manufacturer’s warranty.

          Customer trust is central to what we do. We are rated “Excellent” on Trustpilot and Reviews.io, and we continue to focus on giving you the best possible experience — from competitive pricing and expert support to fast delivery and an easy 60-day returns policy. Our Price Promise gives you extra confidence that you are always getting genuine value.

          Behind the website is a friendly, knowledgeable team led by PGA professional Mark Crossfield, who has over 330 million YouTube views sharing trusted golf advice. Whether you need help choosing the right driver, advice on custom fitting, or simply can’t find the product you’re looking for, we’re only a phone call or email away.

          Thank you for shopping with The Golf Shop Online. We look forward to helping you enjoy your game with the right equipment and service every step of the way.
