What you may be alluding to is the NCOWS unapproved finish of the bead blasted look of the SS USFA Rodeo ( both SS & Dull Blued)
and the dull Mulinum or Hombre by Uberti...
They are OK for SASS I believe
The Shiny SS is NCOWS approved as it does memic Nickel.
BTW , the short lived 4 crazy colors... camo green, mustard yellow, desert tan that looked pink , and black
USFA offered on their SAA some years back never was even concidered by NCOWS not sure about SASS...
