I can say the M9 is much tougher built than the Sony A7, and I would trust it as much as as a single digital machine can be trusted.
M9s have been in the wars, to antartica, and many wild places. They've been dropped and generally beat up.
When one does go down, you tend to hear about it, so there is some impression "it's not reliable"
so far, not my experience.
Even the freezes, which I used to often get, are now a thing of the past. I found some memory cards it likes, and I know when to let it "catch up". Haven't need to remove battery as a "reset" for months and thousands of frames.
I don't baby it much:
