打过朋友的1903， 除了保险以外，还有个什么类似训练用的开关？
找到了， magazine cutoff switch.
"The idea behind it was to load the rifle up, switch the magazine cut off switch to OFF, and single feed loose rounds into the gun, until such time that rapid fire was required, then switch it to ON for rapid fire. It blocks the bolt from moving fully to the rear, and therefore keeps the bolt from stripping the rounds from the magazine."
