I've been tempted by the Springfield XD
I tried the .400 Corbon 20+ years ago, and eventually sold it off. The neck is just way too short to provide adequate bullet tension. One round might chamber fine, and the next might shove the bullet back into the case, resulting in a way overpressure round.I'm going the 400 Cor-Bon/40 Super route.
I'm aware of "cons" of 400 Cor-Bon, but for my purposes the "pros" outweigh the "cons".I tried the .400 Corbon 20+ years ago, and eventually sold it off.

I had issues with both reloads and factory ammo.
I was shooting in a 1911. Some other design may feed more gently and not shove the bullet back into the case... or maybe not.
Just be aware. I’m much happier now with a 10mm.
If I were limited to only one pistol cartridge, it would be the 10mm. Most flexible of all the autoloader cartridges - it can be a lot of different things. If handloaders were 30+% of the shooting population, 10mm guns would probably sell similar volumes to 9mm.
Got that same gun, the RIA. It's a pleasure to shoot but had to go back to the factory for mag problems. They fixed it . Now it runs well.
