8.3.7.1 Self-loaders – Release the slide and pull the trigger (without touching the hammer or decocker, if any). If a handgun has a device which requires a magazine be inserted to enable the trigger to be pulled, the competitor must, on issuance of the above command, inform the Range Officer, who will direct and supervise the use, and subsequent removal, of an empty magazine to facilitate this process.
