I used to have a 10mm and I could shoot it very well. It was a G20. I found as a non-reloader, ammo was too sparse and expensive. Still wish I'd kept it but if I was thinking about addressing your circumstances, I'd probably be on the same track and with an eye toward the xtreme penetrator Lehigh or underwood, possibly Buffalo bore. Those are some spicy biscuits and they will drill in deep.
For raw power 44 mag revolver wins, especially with longer barrels. But they are also bigger, heavier, limited to 6 rounds and there isn't a practical way to attach a light.
