I came up with a question. Why is the gap in the slide cover plate there? All you can see or get to through it is the connector. Is it a dirt/water vent or a maintenance window.....? Or ???

The connector and part of the trigger housing stick up above the frame. If those gaps weren't there you wouldn't be able to field strip the gun or reassemble it.
