Fiber optics front, black for the rear sight on all my rigs. They work for me and hold up in IDPA.
I have always liked fiber optic sights on several pistols & the ones that come on some Performance Center M&Ps
My SD9 (2016) came with HI-VIZ sights. I like them A LOT.I am a fan of FO sights. They really help my aging eyes acquire a sight picture under most lighting conditions. I have red and green and prefer red for bright sunlight and green for subdued lighting.
I prefer Maryann and some of her coconut cream pie; but being stranded on a desert island, I wouldn’t hesitate to show Ginger some of my survival skills.
The new Colt King Cobra comes with a very nice brass bead front sight. But, I was having trouble picking it up. I changed it out with a fiber optic sight and it works much better, for me.
