An open action and an unexplained weak report

A candidate is practicing at an approved range under an instructor’s control. The candidate removes a detachable magazine and assumes that the firearm must therefore be empty. The instructor points out that the chamber has not been checked through the prescribed process. In a separate supervised firing exercise, a shot produces an unexpectedly weak report and recoil. Another participant proposes firing the next round to push any possible obstruction out. The exercise provides no manufacturer-specific malfunction procedure or permission to perform repair. People remain near the firing line, and muzzle direction and trigger discipline must be maintained throughout. The candidate must explain the recognition and safety boundaries without inventing a tactical clearance sequence.
