His skin isn't stronger than adamantium.
In Days of Future Past both he, Storm, and Wolverine were killed by Sentinels. When he and Wolverine got blasted by a Sentinel's beam:
He melted, and Wolverine's flesh was completely burned away--leaving his adamantium skeleton intact, not a scratch on it.
His armor was also pierced during the Mutant Massacre. A member of the Marauders (Riptide or something) who could spin very fast threw a crap load of throwing stars at Colossus. Most of them bounced off, but some of them got stuck in his metal skin. He nearly died from this attack.
I'll bet anyone $5 that those throwing stars wouldn't have pierced a sheet of adamantium.
first off I like to piont out that coloussus character was re done at first wolverine claws could not go through him but then the righters realize how stupid that was because that would make coloussus almost un kill able so they change it and u see in later comics wolverine was able to cut right throu him. also this holds true for the ultimate univers also

i agree..i think it's the leverage behind the adamntium claws that would see whether logan could pierce piotr, but, if you shot a warhead at colossus, and shot another one at a adamantium equivalent...which one would sustain the most damage?
obviously colossus... but thats a warhead...
