So you had a good experience. But gave no indication as to how to find your specific adapter that worked so well for you. Almost all adapters I have heard of (including the one adapter I have for the Contax G) focus past infinity.

My guess is you will need to make a very thin shim that will go under the M mount portion of the adapter between the barrel that moves the M mount a few hundredths or thousandths of an inch from the sensor.

I imagine the tolerance in the manufacture of the adapters leave enough play that they go on the safe side and make it focus past infinity instead of not making it to infinity.
