Nite Sight Troubles: Beretta 92FS

[FireInTheHole]

Hi,
After 4 years of hard use the front night site on my 92fs inox somehow dislodged itself on my last trip to the range...

Needless to say, I never found it.

I've heard that replacement of the tritium capsule can be... tricky. Just how difficult a task am I looking at if I choose to do it myself?

I would be very surprised if you could get a nite sight manufacturer to sell you a vial or tritium. Might require a trip to Gunsight.
