I have a 7” KKM barrel headed my way for my Glock 40. I plan to try 38-40, 180 gr soft lead cowboy action bullets in that gun. I have a good supply, will see how they shoot. They’re very accurate in my 1910 vintage Win ‘92. Hope the Glock/KKM combo shoots them as well.

See my reply about those in the other thread in the Handguns forum. Soft bullets like that are generally a poor choice in high pressure loads like the 10mm uses.
What if I don't push them to the wall, drop back enough to cycle the action?

Should be OK if you keep pressures low; use the stock spring and load down till it just cycles. Universal might be a good choice there?
I've done plenty of that in the 40, but in the 10mm I rarely load anything but full power, so I'm sorta guessing on powder choice.
