I just saw the excellent pictures and think , that the
factory just ignored the clean removal of the unecessary "left-over"
from CNC machining. It is ugly, and does not fit the image of a high
quality and overly high prized gun. I never saw that on the German
or Norinco made guns ! What does SigArms in Exeter (USA) say ???

If they are west german they are not machined slides. They are folded steel with an end piece welded into position.
That is correct. The breech block is a separate unit, nicely fitted
in the rear and only held with one dowel pin. Not good enough !
Mine broke twice. No, no "overloads" !

Yes, the "naked" slide is but one stamping on powerful punch-presses
out of high quality sheet-steel plates , cut out in such a manner, that
by one "blow" from above the entire slide is formed, including the radius
on the rear, (a la PPsh 41 Russian sub-gun upper receiver)
The breechblock is a quality casting (would you believe it !) then quickly
CNC machined and simply inserted into the slide which has a approx.10 mm
groove lengthwise and a short one at right angles to support the breechblock
on top, and a small hook-up in the back. Entire unit is
held together on the slide with one dowel pin.
Should that dowel pin brake (it did on me) then the breechblock will drop
in the front and the gun will not feed and shoot anymore.
