I picked up my second Rossi M92 a 24" Octagonal .357 Mag a few months ago.
It took me 2 yrs to find one in, I'm a Dealer and all my Distributors sell out as soon as they get any in.
I got one of four my distributor got in, snapped it up at 1:00am right after they updated their inventory.
I can get .44Mag and .44 colt but finding a .357 is almost impossible.
Both my Rossi's are .357 and I love them, they shoot great with both .38spl and .357.
If you want to you can smooth out the action and replace the safety and Mag follower to improve performance for CAS.

I've seen a couple of Used Rossi's pop up on The High Road forum from time to time.
