There's always the Model 610 revolver. It's listed on the S&W website as both 10mm and 40 S&W. I have one and I love mine.
Logically, unless every single 10mm case was the exact chamber length for the rim to touch, it is not head spacing on it, the extractor is holding it...I am pretty confident that every 10mm case is not perfect in every 10mm chamber...
