If you compare the Hornady's 10mm XTP 200gr vs. the 45ACP XTP 230gr the 10mm bullet has higher sectional density (0.179 vs. 0.162) so in theory if both bullets of same solid design are traveling at same speed the 10mm will give deeper penetration. I'm not sure how much penetration advantage 10mm has over 45 Super in real life flesh and bone but I know several people who load and use 250 gr SWC bullets which has sectional density of about 0.175 @ 1,100 fps in 45 Colt revolvers and get complete penetration on large (200+ lb.) hogs from any angle. IMHO this is sufficient penetration for practically any large animal in lower 48 states except maybe brown bears and moose.
As an avid hunter, shooter, hand loader and tinkerer I'm in the planning stages of replacing my Ruger Blackhawk 45 Colt revolver with 1911 and Glock pistol capable of similar performance. I'm planning to converting a 1911 Government pistol and a 3rd generation Glock 21SF to shoot 45 Super. My goal is to safely shoot 230gr Hornady XTP or similar bullet at velocities of 1,200fps from these pistols.
My decision to go with 45 Super instead of 10mm is simply based on my previous experience...back in late 1980's and early 1990's I had a Colt Delta Elite and Auto Ordinance in 10mm and played with them a lot. I loaded and shot thousands of 10mm rounds from mild to wild through these two pistol. Eventually the Colt's barrel link broke along with several other small parts and the AO frame developed a crack around the slide stop hole. I ended up selling the Colt to a gunsmith friend and the AO slide was put on a cheap cast frame that I out together and sold. I didn't have much experience with Glock 20 as I have short fingers so it never fit my hand correctly.
