riffraff, be sure you make a 'ramp' for that ball to ride in, if it just pops into a hole you might never get it to pop out of there again.
Steve, yes, on a vintage luger you have to push the barrel to the rear, hold it there then rotate the takedown lever downward. I'm right handed so I hold the luger in my right hand, push the barrel assembly to the rear with the palm of my left hand, hold it there and rotate the takedown lever downward with my thumb. Before I get chastized, make sure it is unloaded, also the safety has to be off or the barrel won't go far enough to the rear.
