Omega adjustable screw ?

What is the adjustable screw at the rear of the trigger guard on an omega?

Adjusts the angle of the trigger guard when locked up. If it’s out of adjustment the trigger won’t cock (guard interferes with the trigger when cocking). Some versions had a solid block instead of that screw.
