Where can you get parts for Pic 22 cal revolver?

Precise Imports Company (PIC) of Decatur GA was the importer of inexpensive handguns from Germany and Ialy in the 1960s. Most were of very low quality. There is no one source of parts for these. A gunsmith can make SOME parts, however, in most cases, that will cost you more than the $20-$40 these guns are worth.
