When seated and crimped in the crimp groove, these all fall into and out of the cylinders of both revolvers of their own weight.
Throats of my French contract-era (1984) 9mm cylinder are .358", the .380 Rimmed cylinder was simply a "French contract" 9mm cylinder which was rechambered to .38 S&W to lengthen the chambers, and it has the 9mm clip clearance around its outer circumference, whereas the extractor star enables .38 S&W rounds to headspace. That particular gun will eat 9mm with clips or .380-200 without clips.
The purpose-built 9mm cylinder does not require clips to headspace, but does require them to eject the empties. If you will note on the bullet drawings, "front band tolerance negative" - therein lies the clue!
When ordering you can specify different diameters to fit your throats if required.
