Not trying to be a troublemaker here, but are you saying the gun cannot be fired by holding the trigger down while working the slide?

If so, you are incorrect.

You ARE correct in saying that the bolt locks before the hammer impacts the firing-pin, if that is your point. Anything else would be a disaster.

If you stoke the thing full of shells, snick the safety off and hold the trigger down while vigorously tromboning the slide, it goes "Bang" every time.

I know because I just did it out the back door with one of mine.
