I have one of the RIA's in 9mm/.22 TCM, and it seems to be well made. The .22 TCM has plenty of quirks, but that's a different story
As far as a double stack 1911 in 10mm, that's a tough one as STI does not list 10mm as an option in their double stacks. Caspian does sell DS receivers, including titanium:

But there will be lead time to obtain the parts and get them fitted.
In single stack 10mm 1911's today, I'd take a hard look at Dan Wesson's Silverback series. If money is no object Nighthawk makes some wonderful 10mm's. Colt is offering Delta Elites now with frame rails, but AFAIK they don't have fully supported barrels, which limits how heavy you can load.
