Rich..So you don't think it's spring loaded??? Like a bayonet latch???

No I don't. I am intimately familiar with this type of latching mechanism..the same as a Luger. The latch is activated by rotation. There would be no way to fix a rotating spring in this small space. Nor would it make sense to make such a simple latch automatic. The luger has a simple lever..This one should too but whoever made it left it off and made a slotted head. Only conclusion I can come up with is a screwdriver.
