With the Delta or a Ruger 10, & the rest, shooting 40 in them usually works, but it won't work for long.
The extractor is holding the case against the breech face instead of 10mm being properly chambered & headspacing off the case mouth.
I'm not going to set out to prove it, but firing the 40's in the 10mm barrel will surely brake the extractor in time. If not, it's still likely to get spring & out of adjustment.
If I had to? Yeah. But otherwise, like said, I'm not going to take the chance on messing up my stuff.
