[Leica] LTM to M adapter doesn't quite work

[Don Dory]

I would suggest another adapter.  As for the current misbehaving adapter it
is either the locking lug not seating because the receiving hole is just
slightly out of place or one of the four locking lugs is just a tad large.
If you feel in need of a project then darken the back of the adapter
including the sides of the lugs with a sharpie or dark magic marker. Seat
the adapter on your M10 and look for the wear marks or lack therof.
