TBK,
Colt/Sauer is a think of the past (but still available used), Sauer also quit making Drillings. I think most of the current Drilling makers - Krieghoff, Heym, Blaser, Merkel, Zoli, etc. - will make one in this caliber combination, but I would try to find a used one (a much less expensive approach).
Inserts can be used in any Drilling, new or used, and there is no need for them to be made by the original factory.
And another point. If your interest is primarely big game hunting you might consider a double rifle Drilling. One is made in France by Mathelon, with a 20g tube under sxs rifle configuration. Some others are made with two different rifle calibers (and even with 3 rifle barrels). As long as your pocket allows it, Drillings come in unlimitred configurations...
