I installed a set of these on my old XD-M .45.
My eyes are getting so I’m having a hard time with my sight picture using the stock white dot sights. I’m just having a hard time finding the contrast. It takes too long. Then you start wiggling around. You just can’t shoot like that. So I started looking around at FO sights. I decided to give TAG a try, and boy am I happy I did. These sights are top notch. They look great, fit precisely, and they provide that added contrast I need. Plus, you can actually change the fiber tubes quickly, and use different colors if that works better for you. These things are brilliantly designed.
And their customer service is world class.
You WILL NOT regret this purchase!

After noticing my sights on my Springfield XD were losing their bright whiteness, I decided to finally shop for some fiber optic sights. This is something that I'd been planning to do for a while so I started researching.
I came across Tag Precision and was impressed with their offerings.
What impressed me the most is that you can switch out the fibers very easily and don't have to cut or melt them. You simply unscrew the nut on the sights with the supplied allen wrench, pull out the fiber and replace with a new one. So simple! The fiber is extremely secure and I have no doubt they will ever fall out. Plus, they give you extra fibers.
It is night and day difference between the stock sights and the Tag Precisions sights. Extremely bright and exact accuracy. I was actually shocked at what a big difference these sights made.
Last note, the prices are extremely reasonable for the quality of sight you get from this company.
