I like fiber optic sights myself. If it's to dark for them, you won't be able to see what your shooting at anyway. I wouldn't bother with them for a strictly indoor gun though. But outdoors a green front, and red set on the rear are my favorite setup when a scope isn't to be used. I've got tritium sights on both a pistol and a rifle. While certainly "Tacticool", they're nothing special otherwise. The tritium just isn't doing anything unless it's so dark you couldn't tell if your drawing a bead on America's most wanted, your mother-in-law, or Saskwatch. I guess if your wearing night vision goggles they'd be the ticket.
