It has been a few years since my last fitting. But mine had done the same thing. They asked me what I prefer. It was a free Titleist 30 min fit. At the time that I was fit, I do believe that grip size was seen as more of a preference. The thoughts on that may have changed since then. I have not been to a fitter that would be able to keep shafts ready with different size grips to try and do not know if there are any that do. Unfortunately the only other way I would know to be able to try it, would be to regrip a club and try it out.

Yes they can... Just ask

Good point in that sometimes fitters will focus on lie causing a left shot (for right handers) when maybe it’s as much overactive hands at impact. That said, grip size basic recommendations are based on hand size but using oversized or modern thicker lower tapered grips can impact shot shape. Most importantly, using grips that just feel comfortable in size and materials would always be the primary goal.

Grips, like balls, are easy to trial. One of our local retailers has multiple samples on short shafts to try for feel. If 1 or 2 feel better, then fit on 1 club to try. Fittings are focused on shaft and head options. Adding grip options is another level of complexity. A good experienced fitter can answer questions about your gamer grips and make suggestions, but most of us rarely change grips with changing clubs.

Most of us find a fit that feels good. With changing limitations, like arthritis in the hands, getting some recommendations are useful.
