Just brought home my new G19 today with Glock night sights installed. Very pleased with everything!!! But, have a question that I thought would be easy to figure out on my own by doing a little bit of forum searching, but came up confused!!! QUESTION: What 'brand' did Glock install on my G19? Front sight has a Glock symbol on top and 'AJ2' stamped on one side in white letters. Rear sight has Glock symbol, and MH3 stamped on top....with 'AJ' stamped in white letters on one side. Are these Meprolights, Trijicons, or something else? Thanks in advance!! Sincerely, Stan Wanna kill these ads? We can help!
