I'd ask here if I were you

Just off the top o' my head, I bet that the transverse pin which is supposed to go through the lug beneath the barrel has missed its proper hole, so the barrel has been free to move to the rear with the slide but has not unlocked from it. The barrel is now jammed, freezing the slide.
Try inserting a knife blade between the barrel's rear face and the slide's front, through the ejection port. Then try to push the barrel forward, or maybe down and forward, or forward and down.
If you can separate the barrel from the slide, pull the slide back and remove the transverse pin. That should let you take the gun apart, to start all over again.
If that doesn't work, then I am out of ideas.

Thanks a million Steve. That's what had happened. My dad put the take down pin in infront of the barrel. I was able to pull the slide back enough to push down on the barrel and wedge a flat tip behind it and push it forward enough to get the pin out. From now own he knows to just go ahead and pull the slide all the way back and release it before inserting the take down pin after cleaning and putting the gun back together.

We endeavor to please, sir.
