Yes, MD-12 has a release on its grip.  But the actual triggering happens
via a small mechanical release located at the bottom of F[ME]2 body.  I
use FE and FE2 and my MD-12 works on both of them (plus of course, FM
and FM2).  The MD-12 is operable only when the film advancer is in locked
position, but when it is in on position, then you are can use the shutter
release on the body -- helpful when you don't want the MD noise.

The four contact, as far as I know, are used for power supply, triggering
the meter on by half-touching the release button on grip, and flagging
whether the film is already advanced or not.

I never heard of MD-11's.  If they are for F[ME] series then they are
pretty old because I bought mine several years ago and don't remember
seeing it then; but if it is a new product, then it might be for another
model -- each model has its own MD.  I am satisfied with MD-12, it's the
only one you can use anyways.  I did get it fixed after about 6 months
of normal usage; the repairman said he had to replace some parts from
both MD-12 and FE but never found out exactly what.  So MD-12 might be
know for some known bugs.  But then it works just fine now.
