I go for something moderate (between 40 S&W and nuclear) which is 180 Gold Dot @ 1,152 fps / 531# KE
Similar here if interested:

Why not nuclear?
Have 177 fps and about 28% more KE than factory 40 S&W from Glock 22: Speer Gold Dot 180 gr. @ 975 fps / 380# KE
Have as much KE as 357 Sig from Glock 31 and about 20% more KE than 230 gr. 45 Ranger T from 5'' 1911
The extra 20% KE over 230 Ranger T doesn't increase recoil, felt recoil and speed of follow up shots is same. (Speed of follow up shots a factor)
10mm also has a one round capacity advantage in 1911 platform.

If I had to pick a 2nd choice it would be the Nosler 150 gr. at over 1,400 fps
