If the gun fits properly into your hand, pointing it is like pointing your finger. It is an instinctive action, until you screw it up by thinking too much.
The fit is important. Look at the older muzzleloading and ctg. Howdah guns. They are instinctive pointers & have the mass to point well using your peripheral vision.
At 12 yards, using my .54 flintlock pistol & just pointing it, I was able to get a 3" group for 5 shots, in the middle of the 10 ring on a B-27 target.
1,100fps with a 218gr. round ball.
IMHO, .54 too small a bore size for a "Howdah Pistol".
