Which Hi-Vis "tube" do you use most on your handgun?

[Logistar]

I just bought a "Hi-Vis" sight for my Browning Buckmark. I was wondering which size tube and which color seems to work best in general. Any comments about these sights are appreciated!

Also I am having trouble mounting the new sight There is no hole or recess to fit over the "notch" or "post" that appears toward the end of the barrel after the original sight is removed. Therefore the sight won't be flush with the barrel! HELP!

Thanks!

I use a green rear with orange/red front at .09 for a G19. fast, allows precision shots and I do not get the blurring into one that I get with the all green. fwiw, I shoot with both eyes open.
