Yeah; the gun is empty and no mag. When you pull the slide back after rotating the takedown lever to the "remove" position you get absolutely no indication of a point where the slide will lift. I applied a considerable amount of pressure and even rotated the takedown lever back and forth while the slide was back; no go.
The first thing I did was look at the Youtube video.
That was done. The disassembly procedure was followed precisely and it will not go. Right out of the instruction manual and the Youtube video. The takedown lever rotates and you can see it rotate on the off side so it's not sheared off.
