I have one of those with a 4" barrel (still prohib by both calibre and barrel length). Mine has pearl grips, which make it look like it was probably a pimp's pocket gun. But it also has a police serial number (SPF followed by a single digit). I assume the two are incompatible.
It always reminds me of the line from "Bad, Bad Leroy Brown": "He got a 32 gun in his pocket for fun, he got a razor in his shoe" , even though Leroy was a gambler, not a pimp. I wonder if some bureaucrat heard the song and decided that .32s should be the next thing banned.
