How long ago did nosler stop making partion handgun bullets?

So I was cleaning up my reloadin area, and found a box of 180g .357 diameter nosler partion handgun bullets and checked the recent manual (got #7 as a b-day present woot) and all they have is sporting handgun bullets. Then I got to looking and didn't see any partitions for handguns and it got me wondering when did they stop making them? And yah , I know I need to clean more heh, but I had about a 5 year break from reloading after I bought my house. Ive been back at it awhile for rifles and recently dusted off the progressive for handguns. Its a lame excuse but im stickin to it, hehe.
