Recently went to the local range to get some of the TFO Tru Glo's put on my RIA Tactical... The gun smith there told me that none of the aftermarket sights would work for the cut of my front sight, and I needed to send em to a tool tech... He said the can insert Tritium into the stock sights... Then I called Arnel the smith at Armscor and he said that you can mod the front of the slide or mod the actual front site to make it work... Anyone on here know if there is just a sight you can buy and install? They don't HAVE to be the FO/Tritium combo sights, that is just what I prefer... Just some night sights would suffice if there are some that would work... Thanks in advance... Wanna kill these ads? We can help!
