Both!! I have a TCR 83, with 3 barrels. And it would be one of the last ones I would let go of. (But then I can't pick a first) I also have a #3, not a #1. It would also be one of the last to go.
I can't understand the concern about breakage. Not much to break. Innards mostly. (And I've heard that some small parts are still available from TC if you ask real nice.) But then I don't beat on my TCR. Differences? The TCR is a break action single shot. Rather elegant actually. Similar to a NEF or an old Savage 219. But a little more refined, maybe a lot. Ruger#1, built like a tank. Strong, rugged, still fair looking, classic style. Not as well refined, a rifle built for a purpose. Yes they can be made very handsomely, but need a little dressing up to get there.
Again, both!!

And Keith, I did the same thing once, turned down a nicely priced #1 because it was a 458. Ooops. You can always download it some. Makes it easier on that expensive brass.
