Yes, but it was about 10-years later after these were made when Colt started having some models finished in the Electroless Nickel. However, I would say that they are of the same finish as the Satin Nickel Colt Combat Commanders of the 70’s but called something different by Colt for whatever reason. I have three of the Satin Nickel Combat Commanders; 1971, 1972, and 1973. This so called Sand Blast Nickel looks identical to those.What a unique and cool looking Colt Detective Special. I wonder if the sandblasted nickel is the forerunner of electroless nickel? They look awfully close.
