Called Rossi this morning at around 9 am and got right thru - didn't have to wait in the phone cue - and I asked them about the difference between the Rossi new R98 and the Taurus model 94 and Tracker 900 series 22 lr revolvers. Apparently the Rossi fits in between the two Taurus models weight and size wise. It does take an after market grip that would fit a Taurus Tracker, and it does have internal coil springs, like the Tauri do. While the CS person didn't know anything about a 6" model, he did tell me that they were contemplating making a 2", 4" and 6" version and that the 6" version that I saw out there on the net might be a "special run" for one particular distributor or something. He did confirm the hi viz front sight and told me that the rear sight is thick. Hope this helps ya'll and here is a link to some Hogue grips that I know a lot of the Taurus tracker owners use. Good luck and happy shooting - let the rest of us know if/when ya'll get a new one of these - I will do the same!
