Hand guns do not receive hate. The people who try and kill themselves with hand guns simply do not know what they are doing. If you use a full-metal jacket bullet at the side of your head, the chances of failure are relatively high. If you use some little .22 caliber bunny rabbit round, you're just going to mess yourself up more.
Hollow-point, 9mm or larger, in the mouth pointed slightly upwards, and you are going to die quickly 99% of the time, hand gun or otherwise. Both my husband and I grew up around guns with military/hunting fathers. There are five guns in our house now. I'm just too scared to use them for CTB. But it would definitely be quick and easy.
