I bought a sight unseen, police trade in beretta 92fs earlier this spring. When it arrived, it had the usual exterior wear, but was in great shape internally. I did have 1 issue though. The trijicon night sights were dim, and the front one had fallen out.

I called Trijicon, got a price of $18/lamp (shipping included), and shipped it off to them. 3 weeks later I got my slide back with new lamps. It looks great, and damn cheap too.

I'm very happy with Trijicon, and knowing how good their customer service is, I will be looking at their products, over competitors in the future.
