If you don't get carried away with the powder charge any 45 ACP bullet will work. You can keep the recoil down and still knock over any steel you hit.
What is most critical is how the bullet functions is your gun. If it wont cycle, it don't matther how well it shoots.
I use an old bullseye load, 3.8 grs of Bullseye pushing a 230 cast RN lead bullet. It functions well in my 1911s, knocks over any steel target I hit, It's accurate and extremely mild to shoot. (Cheap too).
