Hi all, first time here on rugerforum. I've got this Ruger SP101 that is very unique. I can't seem to find any information on it whatsoever. I'm told it was made for the Department of State. The catalog # is KSP-821DOS. It's a 5 shot 38 special with a 2 1/4 inch barrel. It is double action only and has a strange "commander" hammer that resembles that of a 1911. It is polished stainless. Not sure if the polishing was done by a gun smith or if it came this way? ANY info is highly appreciated! Thanks in advance!
