Johnny was quick on the draw, and of course correct. I would like to add two small embellishments to his description. â??At that point the barrel and frame are stoppedâ? is just a slip of the tongue so to speak...It is actually the barrel and receiver which are stopped...by the impact of the receiver lug on the rear of the front frame well. The inertia of the breechblock and toggle train causes this assembly to continue to the rear. The toggle reaches its maximum travel when the rear extension of the toggle pivots down and contacts the frame thus stopping the motion of the toggle/breechblock assembly (the â??toggle slapâ? can be seen on the rear of the frame of any Luger that has been fired more than a few times). The recoil spring then takes over and returns the toggle train/breechblock to battery.

Of course there are other things happening in this wonderful mechanical process, such as the retraction of the firing pin by the cam arm on the forward toggle link, ejection of the spent case, etc., but the major functions are as described.

Too bad you can't recall the names of the "experts". I have never encountered that rubbish and was curious who might have written it.
