    I field stripped my G20 and now the slide will not go back on. Any ideas? The gun is new and I'm new to Glocks. Thanks.

    Did you mess with the "guts" of the pistol at all after disassembly?

    Is the mainspring assembly in place?

    Not much info to go on to help you with.

    Push down on the firing pin safety and get the firing pin into the fired position. After that I bet it goes right together. Mine won’t go together unless the firing pin safety is in the up position.

    Once you get it to slide past the first set of frame rails, push the trigger forward and push the slide on the rest of the way.

    Make sure the trigger is in the fired position

    Trigger is in the fired position, should it be pushed forward? What does the firing pin safety look like?

    This.

    I'd add a picture to show SuperTac but I don't have a Glock on me today. The firing pin needs to move forward a little bit for some reason with the G20 when putting slide back on. Don't have this issue with any other Glock.

    The little round silver thing. Push in on it with the muzzle end of the slide pointing down and the firing pin should fall into the fired position. Trigger should be fully rearward. Then the slide should slide right back on the frame.

    Same thing happened to me on my G20, had me scratching my head because none of my other Glock's did this!

    Bahahahahahaha!!!!

    You aren’t the only one w/ that problem...seems the trigger is a bit sensitive in the gen4 models and likes to move out of position when you disassemble/ reassemble. There’s a YouTube vid on it.
