Deputy Chief Justice Sir Gibbs Salika, in his ruling, refused the bail application sought by Felix Kange.
"A pistol is a dangerous weapon and people who are in possession must take precaution.
"I will exercise court’s discretion, and the interest of justice does not require that this court grant bail," Sir Gibbs said.
The judge said Kange's statement in the police brief facts shows 'carelessness' on his part when he pulled the trigger in a room with other people in it.
