I think this may be an artifact of copying and old design. I had an old Winchester .22 pump gun with no firing pin return spring. It would be hard to work that action fast enough to cause a slam fire, but it also didn't ignite cartridges with the greatest consistency. Perhaps this wasn't a problem with the chlorate primers of its day? I wound up machining a new pin for it that accommodates a firing pin return spring, and that solved the ignition problem. (The fact the action doesn't support case rims, and modern .22 WRF rims thus are occasionally allowed to perforate under the pressure of modern powder is another matter. This can't easily be worked out of the design, unfortunately.)
