Wiggle the trigger a bit while trying to get the slide back off. Once you do that realign the recoil assembly so it's centered up. Actually it's probably off center a bit but should be true to the slide. It's probably hanging up on that.
Then try again. Let us know how it goes, we'll get to the bottom of it.
