"Further, open bolt sub guns use advanced primer ignition to keep bolt weight down."

Or, you end up with guns like the Reising and the original Thompsons, which fired from an open bolt, but which had the odd and questionablely useful Blish lock.

I know there have been several other "open bolt, but locked at moment of firing" submachine guns over the years.
