Prefer a pre-warning label barrel, but will consider later production. Must be stainless 6.5" for a new model 357Mag is good condition without damage to rifling.
I don't see the warning on it, is something wrong with that barrel?
If you can't find one w/o the warning:
It's just so easy to remove the warning from the barrel especially a stainless barrel, you don't need to re-blue it.
