The normal functioning of the HSc (and also the 1910, 1914 and 1934 models) is that the slide locks back when the magazine is empty, or when it is retracted with no magazine in place. The magazine (if present) can then be removed, and the slide stays back. It is only when a magazine (whether loaded or not) is inserted that the slide will go forward.
Experienced users, wanting to retract the slide to check the chamber, will retract the slide, partially remove the magazine, then shove it back in, releasing the slide.
The concept is fine and reloading is fast. A loaded magazine can be inserted and the chamber loaded automatically with no need to fumble for a slide stop or pull back the slide to release one. But that speed is bought at the cost of a complex mechanism that often goes haywire. In fairness, failure is often the result of an ignorant user trying to force the slide forward or to make the mechanism work in a way it is not designed to do.
