I've looked all over the Internet and I can't find official instructions on how to adjust the rear sights on a Glock 19 anywhere.
It [Illooks like/I] you just take a punch and lightly tap them in the appropriate direction but before I take a hammer to my gun I thought I'd better ask.
To clarify this is a Gen 4 Glock 19 with factory sights and absolutely NO modifications of any kind. I'm pretty sure the sights are polymer.
Thanks
