As follows:<br/><br/>Your pistol has a ROF of S/2/-. This means it fires Single-shot, 2 shots on Semi-Auto, and cannot fire on Full Auto.<br/><br/>Single Shot, you understand.<br/><br/>Semi-Auto works the same as Single-Shot, except that you gain +10 to your firing test, and if you score at least 2 degrees of success (so, 20 lower than your modified BS), you land two bullet hits and roll damage for each.<br/><br/>A Full auto weapon, if you had one, would add +20 to the test, and score an extra hit for every 1 degree of success up to its ROF.
