I ordered the Red HiViz fiber optic front sight and installed it on my Canik TP-9. It was a quick and easy install with the exception of getting the mount screw started. Ironically, I needed a Glock front sight tool to complete the installation. I feel that it is a major upgrade. It looks great and lights up in the daylight. I'll post pictures of the before and after. I'm not sure they will do it justice but it's a start.
