I’ve been playing and building clubs for a long time, and in my experience a standard swing weight for a player’s iron set is typically around D2.

About a month ago I received a custom set of T100 irons with Modus Tour 120 Stiff shafts, standard length. The entire set measured approximately D0.

I also ordered a custom U•250 Utility Iron with a Graphite Design DI-105 shaft. It arrived at C9.

I reached out to Titleist Customer Service because both orders seemed noticeably lighter than expected. Their response was:

“The Utility iron is targeted at D0, but the lightest it can go is C9 and the heaviest is D1. So, it is calculated within the threshold.”

I understand there are manufacturing tolerances and that different shafts and grips can influence swing weight. However, I was surprised that a custom order could arrive at the absolute bottom end of the allowable range and still be considered fully within spec.

Has anyone else experienced this with recent custom Titleist orders? I’d also be interested to hear from someone at Titleist regarding what swing weight target is typically used for T100 irons with Modus 120 shafts and whether D0 would be considered normal for that build.

I’ve always had great experiences with Titleist products, which is why this response was a bit disappointing.
