I just purchased some Trijicon night sights for my glock 19 gen4. The seem awesome so far! I have a question, what are the numbers on the sites? Mine says 10 on it. It has a T symbol thing, H3, and then the number 10 on it. Does this number mean anything?

The numbers represent the year of manufacture. Tritium has a half life of 10 years. meaning they will maintain their brightness for a long time. your sights were made this year (2010). You will not notice any dimming of the sights for a long time
