    When examining a generation 1 G17, how can I determine if 920403 upgrade has been accomplished?

    Compare the striker, trigger bar and firing pin safety in your gun to a pic of the older parts. You can find pics all over the web. You will easily see they are similar (old) or different (new upgrade)
