Just installed some Ameriglo Idot pros on my g19. After many weeks of input from others that own them, finally bit the bullet. Wow, fast front (orange) site acquisition and the Trijicon night is superb. Have not taken to the range yet to test the accuracy but am confident I will be pleased. $72 total at grabagun. Was going to post the link but site was down. Wanna kill these ads? We can help!
