Bamaranger is correct (except for the 'PPK' part, where he's close—it's Polizeipistole Kurz). They also make .38 Special in the Ranger line, most of which must surely be destined for off-duty and BUG use.
They also probably make the .380 largely to serve the civilian market as well as law enforcement. All makers who put out "Law Enforcement" lines know that a fair amount of it gets sold to regular folk. They create an air of exclusivity, but in the end, they don't seem to really mind the rest of us buying it, as it expands their market and keeps the price up. The only Ranger load Winchester seems to go to great pains to restrict to LE (and the only one they actually mark Law Enforcement Only) is their Ranger 127 gr. +P+ (RA9TA). And, while it can be difficult to obtain, it is still generally available to civilians.
