Alexander - I think Mr.Bower is being a little too consevative.
Many photogs (even me) have the ability to hold their rf cameras
steady for 1/30 or even 1/15 if you they lean on a wall or post.
The usual accepted figures are:
50mm lens ------ 1/25 to 1/50
90mm lens ------ 1/50 to 1/100
135mm " " 1/250 or faster
but this would be based on a particular circle of confusion of
1/100" (I think). I am sure that if you made a comparison test
with your camera on a tripod, they would be much sharper but
these figures are for acceptable sharpness, which is really a
subjective term & could mean many things to many people.

Brian Bower wrote in his book "Leica M Photography" on page 49:
"In my experienc camera shake is the biggest single cause of unsharp
pictures. Many photographers are wildly optimistic about their ability
to hold a camera/lens combination steady. To be reasonably certain of a
perfectly sharp result my rule of thumb for minimum shutter speeds with
the different focal length Leica M lenses are:
Lens shutter speed
21/28mm 1/60 sec
35mm 1/125 sec
50/75mm 1/250 sec
90/135mm 1/500 sec"
When I read the following lugmail I wonder.....
Marvin,
I use my "Leicas" R version regularly at 1/15th or 1/30 and I don't see
any
mirror "bounce effect". I might as well add that I do the same shutter
speeds with the "Leica" M version and I know there isn't any there! :)

I don't want to insult anyone, but if you ask my opinion I would say
that the recommended minimum shutter speed by Brian Bower must have been
meant only for people with parkinson :)
I am told that, because of the absence of a mirror, the M-camera can be
used at comparatively longer shutter speeds than a SLR.
Any opinions?
BTW, once again I like to express my love for the M(asterpiece). I just
got my slides (fuji sensia) back!
