9mm Luger out of a 9x21 revolver - accuracy reduction?

I got this idea from reading sigcurious' thread ".38spl out of a .357mag, accuracy reduction? "

I think a revolver chambered for 9x21 IMI must use moon clips, and those moon clips would fit 9mm parabellum - the base for both rounds is 0.391 in.

But compared to something like the Taurus 905 - where the case head snugs up to a rim in the cylinder, the parabellum in an IMI cylinder would have a 2mm "jump" to traverse in the cylinder.

Would that reduce accuracy?
 
Trouble is both the 9x19 and the 9x21 are tapered cases. You won't get the same support in the chamber as you do with the cylindrical .38/.357 combo.
 
Well, it has been done.
You can get moonclip conversions of .357s that will shoot 9x19, 9x21, 9x23, and .38 Super out of the same chambers. The tendency is to buy big and shoot small. Whatever the loss in velocity and accuracy may be (on top of what may be given up by the conversion itself) people will go to the load that costs the least and kicks the least.

Some of the few S&W M940 9mm J frame revolvers have been rechambered to 9x23 for greater power (and easier ejection by cleaning up the rather rough factory chambers.) The tendency is to shoot these with 9x19 for practice.

There is a number of S&W M610 10mm revolvers being shot routinely with clipped .40s for lower cost, lower recoil, and quicker ejection.

I guess my question remains, where is there a 9x21 revolver?
In Italy where private ownership of a "military" caliber is not allowed?
