I am now confused about the tape thing. The tape test for a weak spring is to put the tape on the rear receiver where the rear toggle link tail hits the back face of the receiver? I read the e-book on lugers and it said this: The toggle knobs reach and follow the ascending slopes at the rear of the frame, the toggle joint is accelerated rapidly up past dead center. The rear slopes of the receiver and other areas which can give good clues to knowing whether the gun was used intensively. Repetitive strikes of the toggle knobs against the slopes progressively crush polish them. In some rare cases of heavy use, the metal can be deformed. On the other end of this wear spectrum a luger with little use, the receiver slopes are still retaining almost all their blue finish. On the subject of the rear toggle link’s tail, the e-book said that with time traces of wear appear on the back face of the receiver. These traces are good indicators whether or not the pistol was fired a lot. So here is the question, if repetitive strikes of the toggle knobs on the slopes over time causes wear, then this is only a sign of heavy use? Then using the tape method on the back of the receiver is the best way to check for weak spring? If it passes the tape test then leave the spring alone?
