I recently bought a new P30, and will soon be getting night sights for it, as I get for all of my pistols. I'm just curious about the Heinie straight eight QWIK sights, and was wondering if anybody has used these sights and is willing to offer their opinion. I've always been a 3-dot kind of guy and don't know if I should make the switch or not. This is my HD pistol and occasional CCW. Thoughts?
