Checked with them this morning, they do have the .44 barrels in stock.
I had let slip the cost to ship to them, so I'll factor that in too.
The plus side is I know that if it's fit by them, it'll work. I'm mostly certain a purchased barrel will work, but there's always that shadow of doubt. That, and I've lost money in an ebay rip off before, so I'm always a little bit hesitant.
I will watch it
