The Series 1 is a traditional muscle-back blade from McLaren Golf's debut iron range (launched 2026), aimed at better players and tour professionals. The heads are metal injection moulded from a proprietary steel blend with internal tungsten weighting that shifts CG progressively low-to-high and heel-to-toe through the set, paired with a progressive offset package. A silicone dampening system tunes feel. Sold per head through select custom-fitting retailers.
