Hi Dave,
Unfortunately, due to new regulations we can no longer install or re-lamp tritium in non-removable sights. Trijicon is offering some warranty and non-warranty tritium lamp replacement. You may contact them at (248) 960-7700 to see if your slide qualifies.
We do have a new option available for Beretta 92 models with existing tritium. This option will be for us to machine off the existing front sight and install a dovetail. We then install a new custom three dot sight set. This new sight set maintains the existing height of both the front and rear sights. The new front sight is also pinned in from the top of the sight. I have attached photos of this installation. The cost of this installation is $275.00 plus an $18.00 shipping fee. Please note this is custom work and may take up to 10-12 weeks to complete.
This option is available in Bright & Tough style and HD style. The front sight outline ring is available in white, yellow or orange. I have attached photos of the different color outline rings. You will also have the option of green or yellow tritium lamps for the rear sight. The front sight will have one green tritium lamp.
If you choose the HD style sight set a glow powder will be added to the outline ring on the front sight. This will also have a serrated face, u-notch rear sight with no outline rings. If you choose the Bright & Tough style sight set the front sight will have a standard outline ring in the color of your choice. The rear sight for this will have two white outline rings surrounding the tritium lamps. This rear sight is similar to the Trijicon Bright & Tough series.
I have also attached an order form for your convenience.
Please let me know if I can be of any further assistance.
Thank you & have a great day,
