Opinions are worth exactly what you paid for them.My simplistic interpretation of the article is " it's terrible but relatively safe, so we'll keep using it " and, all these terrible things "are not well understood". My reply is therefore "huh?" (And boy howdy, I have read more than my fair share of technical publications.)
I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.
The current US service pistol made by SIG-SAUER has a stainless steel barrel.I've read quite a bit on carbon steel Vs stainless. There's more advantages to carbon steel, but stainless has some advantages over carbon like being more rust resistant.
I believe stainless rifling will become shot out sooner.
Stainless tends to become sticky with friction.
The US military has no stainless steel barrels in there arsenal either.
I could be wrong on some of this, but that's what I remember
