Recently heard that the M-1 carbine ammunition was (of the) the first widely-issued military cartridge that had non-corrosive primers.

Any truth to that, or is it just American-based fact? I know about the 7.5 x 55 Swiss, naturally...

True, right from the start. And that's why you see so many Carbines with their original barrels versus M1 Garands.

Americans have said it was the first, but I suspect many of them never did there research and found out about the lovely 7.5x55 Swiss (which was non-corrosive off the bat). It definitely was one of the first non-corrosive mass issued rounds though.

You're right about american lack of research (this doesn't surprise me) however wrong about the first non-corrosive round. The Swiss adopted the GP90/03 which
was an evolution of the 7.5x53.5 used in the earlier straight pulls so that would likely be the first mass issued not the later 7.5x55. The early 6.5x55 Swedish and Norwegian rounds aren't corrosive to my knowledge and that was adopted back in 1891 with production getting into gear in 1894. I could be wrong about 6.5x55 though.
 
I always thought the GP-90/03 used a less corrosive primer, not a completely non-corrosive primer as well as using only semi-smokeless powder, well the GP-90/23 being fully non-corrosive and using smokeless powder.

I don't know about Swedish ammo, I always figured it was similar to everyone elses for the time frame of corrosive to non-corrosive (as otherwise it tends to get commented on). Definitely going to have to do some more research on Swedish rounds.

The whole semi-smokeless thing has been busted as being mistranslated for a while now. It has been tested and shown to be proper smokeless from the start. GP90 originally had a corrosive primer and a paper patched heeled bullet. Gp90/03 changed it to a non corrosive primer with I believe the removal of mercury fulminate. GP90/23 was the switch to a fully jacketed non heeled bullet. Further reading (and watching) can be done here: ht tp://www.thefirearmblog.com/blog/2016/07/01/busting-myth-semi-smokeless-swiss-ammo/
