"shiny" it isn't. I keep hearing references to how the black paint on the M9 is like anything Leica previously has offered... and it isn't. Its quite a flat black, closer to look of the 'black chrome' finish than the recent paint work on the MP/M8.2, and so far for me much more durable.
If you like black, wait or look around for immediate gratification. If it doesn't make any difference get what you can.
Maybe its my classic Leica ideal, and that I have and have had older BP film cameras, I just like the black look, and when the paint starts to wear it has a nice golden highlight elegance to it - 'classic aged' I could call it 😉
As for the 'steel gray M9', I thought of one myself, but black was the one, and only one, they had for me. Happy that was the way it was, easy to 'choose', and really what I wanted. I just sold my MP 'gray' anthracite to help pay for my M9, and although I thought it looked great new, with the light use on it I can't say it would be 'beautiful' in the long run, just beat (if that makes any difference). The gray has a black under-coat primer, so its gray to black to brass - three in one!. Also the steel gray is now suppose to have an improved paint work, tougher than the first run that came out, which from what I heard was a bit 'thin skinned' 😱
Good luck, what ever you decide you'll be happy with a wonderful camera.
