I would like to give you a different suggestion. Personally I have an M3 and a 50 Summicron rigid, but recently I also bought a 40 summicron and it makes a great impression on this camera. No problem for the viewfinder, just use the whole framed surface.
The advantage?
1 - A slightly wider angle of view than 50.
2- A weight and a size much lower than the rigid 50.
3 - A minimum focus of 80 cm instead of 1 m of the rigid 50.
If you put a piece of tape over the center window, the 50mm frame lines will disappear and using the full view will seem more natural.
When using a 50mm lens, stick the tape to the baseplate where you will be able to find it again.
