Saving my money for a new Glock and this GSSF certificate is making my hand itch. Anyway, I am considering the Glock 30sf or a Glock 23. The options in night sights are Trijicons or the Glock night sights. Is their really any difference between these choices of night sights? If so which would serve me better? There are two places listed in my state that are chosen to handle the certificates. One appears to be out of business and the other has a less than stellar reputation for dealing with their customers.:aargh4: Frustrated by this. Any suggestions for my situation? Thanks for the input.
