I'm undecided that it will help or not , my theory is recoil generates muzzle rise, he may reproduce more muzzle rise but he cannot reproduces the recoil that causes the muzzle rise Control the recoil control the muzzle. But if you have a device the controls the muzzle you can get back on target. Just put a devise on the .45

Or maybe your shooting in a stock class only and are not allowed this type of a modification?
