I suppose I should have worded that better. They're not illegal but they changed the case to brass and renamed them to Ranger-T and restricted public sale to law enforcement.
As for the RIPs, I doubt they're a gimmick. You sure as hell wouldn't want to get shot with one and that's pretty much the point, to stop the aggressor.

The Ranger is a slightly upgraded version of the Talon, and it's not illegal to sell them to people. There are several sources on the net. It's just that Winchester doesn't want to sell them to other than LE, but once the ammo hits distributors, that's pretty much out the window.
As clear as I can say it, there's no legal restriction on Ranger, HST or any other non-armor-piercing (as defined by federal and/or state law) handgun ammunition that prevents you or I from buying it.
