I just got my trijicons installed by SA about 4 months ago. Today I was drawing and dry-firing in my house, and I noticed that slight hint of yellow seemed dim in the left rear dot... I turned off the lights and surely enough, only 2 glowing dots. Has this happened to anyone, and does anyone know what SA can do for me about them? Will they make me return the whole slide, or do you think they'll just have me send them the broken rear sight?
