I am considering the Gemini Customs front sight with the gold insert. My Trijicons, installed in a couple of my SP101 snubbies by Jack Weigand, are going dim, especially in the oldest one, which I bought around 1997. I don't necessarily like glowing tritium, anyway, and have handled some guns locally that had gold blocks or dots in the front sight.
For anyone wondering about Gemini Customs, it is first-rate work. Mr. Morganti is carrying on Jack Weigand's custom work, which includes Hybra-porting, as well as his own ideas. Mr. Weigand is still around, but he stopped doing custom work. Two of my SP101 snbbies were given the "Tame the Beast" package by Jack Weigand, though they are not Hybra-ported. Back in the 1990's Ruger revolvers usually NEEDED custom work. A few years ago, Ruger learned how to really turn out revolvers that are smooth from the factory, though of course, Gemini or another good 'smith can still make them smoother.
