Kudos to the mangaka. The two main characters have control of their guns; then leave the trigger finger OUTSIDE of the trigger guard. That is the way you have your gun in possession but make sure a simple little bump the gun will not misfire. If it does fire, dissemble the weapon and look for broken parts, or if you do not feel comfortable, then let a gun smith figure it out and have it repaired.
Oh, My work is gun related. Just because we learn this sequence all the time, people still make mistake.
Oh, if you by chance being able to go to a range, remember one thing: If you see your classmates drop her gun or her rounds (bullets) are all over the place' don't wait. GTFO. Talk to the trainers as soon as possible because guns are serious issues, and both you and your trainer will go to the office telling what happened. Usually at this point the manager will be very very respectful and very very polite The more normal case would be send that person home and tell the person come back a week later. The more serious case, such as horse pay, would be an automatic lifetime ban at the range.
