Hi Dave
Not sure about those codes, but if you mean the code on the front of the manual it is a USB type.
I have only used this on my .22 Anchutz target rifle, It should fit a pistol, just clamps to the underside of the barrel in the same way.
I found this picture on the internet which may show how its fitted ( I did a search for USB SCATT on a pistol, and looked at the images)
