That level of quality in a revolver is going to cost some serious money - as in $2K and up.

It would be a niche market, for sure. I don't know how many bullseye target shooters there are anymore.

Do you think a 10mm pistol could be made to cycle .40 S&W in the fashion of the .357 mag/.38 spcl?

I suppose someone would have if it were practical.

No, and the reason why is how the cartridges headspace in their respective chambers.

Revolver cartridges headspace on the rim (or, more precisely, the front edge of the rim).

A semi-auto case like the .40 or 10 headspaces off the front edge of the case mouth. This means that the .40 has nothing but the ejector hook holding it from headspacing too far forward into a 10mm chamber.

The .40 killed the 10mm, mostly because the only difference between the 10mm and .40 is achieved by loading the 10mm to its real potential, which is well above what the .40 achieves, and high enough to cause some 10mm pistols to start developing issues like frame/slide cracks, etc. As a result of the ferocity of the full-house 10mm, the FBI down-loaded the round to give the ballistics of what became known as the “FBI load” in the 10mm, and that in turn fostered the .40 S&W when Smith noticed “hey, that load leaves all this unused space in the 10mm case, so why not just cut down the case, and we get a smaller grip size and we can double-stack it?” Lo, the .40 resulted.

The only solution (real solution) I would see to cycling a 10mm auto with a .40 S&W cartridge would be to obtain another un-chambered barrel for the 10mm auto pistol, and chamber it for only the .40, and then you’d be off to the races.
