In my experience a 10mm,180 XTP at 1300+ FPS penetrates about the same as a 45 Super 230 XTP @ 1000+ FPS. The difference is the 45 Super expand significantly larger and leaves larger holes. IMHO the Super is higher on the food chain.
This ^^^ and the fact that the .45 has a better chance of performing well if expansion is less than expected.
As a single point of comparison: One of my hunting buds has thus far never experienced complete penetration with 180 gr hollow points from his Glock 20 whereas I have gained complete pass through performance with half of the 200/230 gr HP's fired from my Glock 21.
