Making fiber optics front sights

[jg rider]

Good morning, working on my first cup of coffee. I don't remember if I ever posted this before.
Some time back my grand daughter's night sights on her P9 went dim, so she decided to go with a front fiber optic like the wife and I have.
So I decided to try to make some, and it worked

Nice! Fiber optics for some reason haven't seemed to work for me. Last week I installed some new sights on an officers gun and he wanted the yellow tube so I had to swap it out from what it came with.
The yellow actually showed up pretty good for me. I think a larger diameter rod which I think is available might work for me. Or even melt the tip a bit bigger.

I'm color blind so a lot of colors just blend for me and don't stand out like normal humans.
