I see now.  Then what you need is to get the space factor of the last
letter in the argument of \uppercase.  Something like this:

------------------------------%<------------------------------
\def\uc#1{%
  \setbox0=\hbox{#1\xdef\ucsf{\spacefactor\the\spacefactor}}%
  \uppercase{#1}\ucsf
}%

\uppercase{m}. m\par
\uc{m}. m\par

\bigskip

\uppercase{M}. m\par
\uc{M}. m\par

\bye
------------------------------%<------------------------------

Best,
Oleg
