The RS300 features a two‑piece foam‑filled hollow body construction, combining a 431 stainless steel chassis with a heat‑treated S450 face for explosive performance. This premium build mirrors the design philosophy found throughout the RS iron family. The internal foam filling helps dampen vibration while keeping the face active, creating a solid and stable impact feel with muted, confidence‑boosting feedback ideal for developing golfers.

A 20% thinner S450 face increases deflection at impact to deliver strong ball speeds across an impressively wide portion of the hitting area. The RS300 is engineered to maintain distance even when contact isn’t perfect, helping players achieve more predictable yardages swing after swing. Whether the strike is centred or slightly off, the RS300 keeps ball speed high and performance consistent.

Designed for players who need the most support, the RS300 includes a fixed toe weight port that boosts perimeter weighting and delivers the highest MOI in the RS iron range. This exceptional stability minimises both distance loss and directional deviation on mis‑hits. For golfers seeking maximum forgiveness, the RS300 provides a dependable, repeatable performance that keeps shots on target.

The RS300 positions its centre of gravity lowest and deepest within the RS family, promoting maximum launch and a higher peak height. This CG setup helps golfers achieve powerful carry distances while generating a softer landing, especially helpful for holding greens with longer irons. The ball gets up easily, flies high, and comes down under control.

Featuring the largest head profile in the RS lineup and increased offset, the RS300 offers a look that inspires immediate confidence at address. The additional offset helps encourage face closure through impact, supporting straighter ball flights and reducing the tendency to leave shots out to the right. Every visual cue is designed to make the club easier to aim, swing, and trust.

A wider sole design enhances turf interaction, helping the club glide through the ground more effectively. This improves performance from the fairway, rough, or uneven lies and makes the RS300 exceptionally playable in a wide range of conditions. It’s engineered to help golfers make cleaner contact more consistently.

The RS300 comes equipped with KBS Max steel shafts to promote higher launch and added stability, ideal for players needing help elevating the ball. Additional KBS and Fujikura options are available through custom fitting. Full set options include 5–PW + GW + SW for complete gapping coverage.

Purpose‑built for higher‑handicap players, the RS300 delivers the easiest launch, the most forgiveness, and the most consistent results in the entire RS range. It’s the ideal iron for golfers seeking more height, more stability, and more confidence with every swing.
