A shot to the head is quick and painless. Instant death.
A shot to the chest may be slow and unpleasant.
Most suicides I have read about using a pistol, are a shot to the head.

Of course if you put your thumb on the trigger it is easier.
I don’t buy it.
Coincidences do not happen in twos and threes and fours.
