Now I get what the "P" in M11-P means

I just had to adjust the rangefinder of my M11-P Safari which was misaligned both horizontally and vertically (maybe riding in the pannier on my bike was not ideal).

The "P" saves you to peel off the Leica emblem and fix it afterwards. Instead, you can start right away using a screwdriver for removing the screw and then adjust the vertical alignment. Took just a few minutes.

Thus, the "P" seems to stand for "practitioner" ... 😉

Yeah mine is also misaligned vertically.. still deciding if i have to do it at home.. which screw driver used to adjust the focus patch?

Reportedly, it is the same 2mm Allen key that is used for the horizontal adjustment:

 It is very difficult to see, but it was my impression that it could also be a Torx T6 at the bottom of the screw.

Now I know what 'tough' means in Sony Tough cards: the twin contacts meant I had to use small pliers to remove from my new Safari M11P! 😃

No, both are 2mm hex key.

Allen key is another term for hex key as the Allen Manufacturing Company patented a safety screw with a recessed hex in 1909. The "Allen Key" was the tool used for their safety screw.  In the US (perhaps elsewhere?) Allen key and hex key are synonymous.

The adjustment is easy. What is also easy is cross threading the screw back in or scratching the screw. To loosen I used an adapted spudger and to re-tighten two toothpicks so as not to cross thread. At least I did the first time. Second time I rushed, used the spudger and then had a fixed on, sideways mounted screw which needed a trip to Leica to fix!

I've got a cross screwed (and scratched up) one on my M10M. For now just leaving it. If I do need to make a vertical adjustment, take the whole top off, unscrew it from behind and then make the adjustment. The threads are messed up so it always cross screws back on now.

Of course one should make the adjustment with utmost care and only with good quality tools. I was also concerned about the typical kind of fails that may happen - bearing in mind to deal with a 9k€ camera, and more important with possible Leica service repair times of maybe 6 months if you are lucky...

It's like sensor cleaning - the first time I felt extremely nervous, but now I'm used to it.

What is annoying about the vertical misalignment is that you will never have a sharp overlay of the rangefinder patch, unlike for horizontal misalignment.

You will if you tilt the camera at the correct angle!

In UK I think that Leica have started doing adjustments without sending to Germany.

I think you can have the sensor cleaned and the RF adjusted in a lot of (flagship) Stores, without having it sent to Weltzlar.

And if you have the opportunity to be / to go to Wetzlar, just schedule a meeting with customer care, leave them your camera, and they do it on the same day.
