They've been sold out for years, like 940 cyls. Keep an eye out in the classifieds here and also on ebay and hopefully you'll run across one.
I think all of the old stock of Ti cyls has been pretty much depleted now. I ordered a Ti .41 mag cyl from Numrich's the other day for an M28 conversion project but that's the last caliber they had in stock.
And, since everybody else posted pics... This is my 360J convertible, the original steel cylinder has been rechambered to 9x23 and cut for moonclips so it'll shoot 9mm, .38ACP, .38 Super, 356TSW, 9mm Largo, etc., and it's had a Ti .38spl cyl fitted to it as well.
