cda926, thanks for your posting/pictures very much. Several years ago, I was made aware that the Atlanta PD carried the PPS (square butt) in 4-inch barrel lengths during the 1920's and 1930's. The rank and file uniform Atlanta policeman of that time period was issued this fine Colt Revolver, in .38 Special caliber. I was not aware, until this posting of yours here, that a 2-inch PPS version was also present within the Atlanta PD. I would assume this model was for the plain clothes officers and detectives. Learn something new each time I visit this great forum. Thanks again sir!
