Well, then, look to the Rolling Stones for your answer:
You can’t always get what you want.
As for bringing up .45 Super, it was a fairly logical assumption that you were unaware of it, since you were asking about using a doublestack magazine (XDm) in a single stack pistol (XDs). Just pointing out options you may not have considered. Didn’t know that the 10mm was the only cartridge you could consider.
By the bye...compact 10mm's are rare birds. The G29 is, afaik, the only one that's in major production; Tanfoglio may still make a compact Witness, but that’s a DA/SA, hammer-fired platform; RIA makes a Commander length 10mm 1911 in both single and double stacks, but those are few and far between. So, you may need to adjust your expectations.
