Actually you have some options, I won't say they are great but.......

Long Head Space: The model of 1917 almost fails a field reject gauge (same thing can be done with a no go and a piece of freezer tap on the back of it)/
Long head space is not a problem.

So you could go long, that would give you something around .005 or .006 and might be enough to not engage the lands.
You are still stuck with hoping it shoots good up close to the lands.
As you do not reload that's not an issue for the brass

Set the Factory Bullets Deeper: all depends on the crimp, grove but you might be able to get a hand bullet seater and nudge the bullets back. Not something I have tried but its a thought and they don't cost much.

Best option would be to get the chamber deeper.
