"Now that the smoke's gone And the air is all clear Those who were right there Had a new kind of fear"
—Filter, "Hey Man Nice Shot"
There are lots of ways to do yourself in: jump off a bridge, hanging, stick your head in the oven. One popular method in Hollywood is to wrap your lips around the barrel of your favorite firearm, and pull the trigger. One obvious reason for this: not a lot of room for error. Of course, some people still screw it up.
Someone who wants to give you the chance to do this will Leave Behind a Pistol and no, it doesn't mean edible firearms.

Martin Riggs in Lethal Weapon contemplates this form of suicide early on in the movie, but can't follow through. He even has a special hollow-point bullet to make sure his brain is sufficiently damaged. But when he's partnered up with Roger Murtaugh, the latter is so exasperated with Riggs' Death Seeker attitude (which he believes is just a bluff) that he offers him his own revolver to do himself in —and Riggs promptly presses the barrel to the underside of his throat.

Boomer attempts it in "Kobol's Last Gleaming". Doesn't quite work because 1) she's a Cylon sleeper agent and it was against her programming, and 2) she screwed everything else she ever tried up, so blowing a suicide attempt was just par for the course for her.
Brother John Cavil, ostensibly the leader of the (evil) Cylons, does it in response to his last hope of regaining Resurrection going straight down the shitter.
