Really interesting is the breech face of the revolver-- there's the hole for the firing pin and a second hole there as well. I believe it was meant to hold or steady the 9mm cartridge.
IIRC the second larger hole accommodates a rebounding hammer-actuated plunger that prevents the 9mm case from backing out on firing due to its slight case taper.
