Whichever one you shoot best!!!
The .45 has a long track record of success ... so why reinvent the wheel! If you ask the "Band of Brothers" as I did:
Donald Burgett, swears by the 1911 .45 ... not some theories by folks who read or watch or Watch TV ... This man, shot Germans face to face in the deep snow of Bastogne
Listen to Donald, or someone who has never shot real people with a real .45 in life and death to the max situations!!!
