I ordered a pair of these sights (GL-956) around the end of March. I decided I liked them enough to put on more then one Glock, but tonight the GL-956 page is no longer on the Ameriglo website (LINK). Does anyone happen to know if these sights have been discontinued for good? I was really hoping to set up exact duplicate pistols for practice and carry, so now I'm kicking myself for not ordering the second pair or sights sooner.
