I have a Model 64 I shoot ICORE with. Being stainless the front sight is hard to see in bright sunlight. I took some florescent orange paint (that I use on my steel targets) and painted the front sight. Now that sight just screams LOOK AT ME, LOOK AT ME. It helps a lot.
So I decided to try it on my 642, again it really makes the front sight jump out there in bright sunlight.
I have CT laser sights for low light conditions.
Still, the best thing for get on your front sight is lots and lots of practice, dry fire and live fire.
