Detective Special INS

[MagicD]

Have a D.S. long grip 874xxx shooter quality finish but tight with super trigger
Took off grips cleaning it and found INS stamped on left grip frame.
Gov or Colt marking?

 

[Old Fuff]

It a Colt inspector's stamp, not the government Immigration Naturalization Service. Those are marked, but not under the stocks.
