I bought a Gold Cup "kit" - everything but the frame - and I'm intrigued by the collet bushing. When the bushing is in the slide, it's loose. When the bushing is on the barrel, it's loose until it gets within about 1/16" of the muzzle, where the slight step-up in barrel diameter springs the collet. When assembled to the slide, the collet is loose even when it is in the "sprung" position on the barrel. When the barrel is somewhat forcibly pressed into lock-up, everything is tight; but there is a distinct springiness. Kuhnhausen says there should be no spring in the lockup; since the collet is a spring, how can it function without some springiness? I'm going to assemble the parts onto a frame, and I'd like to at least experiment with the collet; is mine working as intended?
