Very common , for Mizuno. I played their irons for 20 years, and have ordered probably 30 sets of irons for myself and friends over the years. I have always checked clubs I order on my Mitchell, because you never know who checked your set after assembly, regardless of manufacturer. Not one Mizuno iron set was ever correct, and most were off in different directions by iron. Don’t get me wrong, Mizuno irons are f’ng fantastic, but their quality control historically for me has been abysmal. Ping has been much better in my experience, with Titleist, Taylormade and Callaway better but with occasional issues. Your mileage may vary, just my experience over the last 30 years.
