- No, at least not on mine or the other example I have handled, repaired etc. etc.
- Yes, focusing is excellent, especially the IIIx generation.
M magnification 0.92x, 0.85x, 0.72x or 0.58x vs III/IIIx magnification 1.5x.

Barnacks got 2 springs that need tension, that's all.

The overall best Leica shutter is in IIIc K - "Kugellager" double ball bearing shutter, cold proofed.
Some wartime IIIc "red curtain" or regular got these shutters too.
LTM or M shutters always travels with the same, constant speed across the frame, only the spacing/slit between the 1st and 2nd curtain changes. That speed is ~ X sync speed: 1/60.
In Leica M3 the shutter was made more complex - more vibration sources, and generally easier to be placed "out of tune" than I,II,III,IIIx.
Have You ever seen any M doing crescent shaped "exposure" on the left hand side of the negative on high speeds, despite the additional adjustment options?
What about M3 DS shutter brake that causes shutter bouncing? Yeah, it was fixed in M3 SS and later M...
In M3 was introduced individual "high-speed cam" adjustment for 1/1000 - wanna bet it "kicks" more than I,II,III,IIIx and its still not real 1/1000?
Later on M got "individual" speeds adjustments - not a source of silence or less kick or bounce either.
M7 introduced electronically "self adjusting" shutter that kicks the most of the M pack...
Still in M7, 1/1000 is more like 1/750 but the good news is that its relatively constant and not much dependent on the 4 seasons temp, RH changes.
The cloth shutter works best and reliable (~20%) up to 1/500 that's why early Barnacks got max 1/500.
Leica did 1/1000 to compete with Contax but it was a proven failure for the cloth shutter.
Any "central" leaf shutter works much more precise, reliable, even at ridiculously low temperatures up to 1/500 and is way ahead than any focal plane shutter for that mater, if we care to go there and You get all speeds to sync.
Barnack's Leica is real pocketable/compact camera system, capable of excellent results and the most important page from the 35mm camera/photo history, everything else is just to fill in the space and satisfy different tastes.
Next stop is medium or larger formats.
