K.C.
I agree with BEARDOG's assessment: it seems you were able to force the slide rearward enough to cross over the cam and the cocking lobe popped back up behind the rear slide cover. Unfortunately, it also appears that the trigger is still disconnected by the slide.

I think you have two options at this point:
1. Try forcing the slide further rearward so the trigger connects and will operate the cam. When this happens you should be able to pull the trigger, hold it rearward, and pull the slide over the cam and off the frame.
2. If you can't move the slide far enough rearward to connect the trigger, make yourself an "L" shaped tool (paper clip should work) and, space permitting (it will work on my CW9, but I don't know about the P380), wiggle it in under the rear of the slide and behind the cocking lobe on the cam. Once in place, try to force the cam's cocking lobe down by pulling the tool rearward. You'll need to manipulate the slide at the same time; both to give the cam enough room to cycle down and to get it off once the cam is down. I'll not lie and say it will be an easy dance, but it can be done.

Edit: I see, that as I was putting my reply together, CJB also suggested this as a fix, kudos. His idea to remove the side plate to manipulate the cam is a good one.
