US Marine Corps FMF CORE Weapons Fundamentals (109) Practice Test

Safety and proper ammunition handling must come first when preparing to load a magazine. The essential step is to confirm the weapon is clear—the action should be open, the chamber verified empty, and there should be no round in the firearm. This prevents any accidental discharge during training. Along with that, the magazine itself should be checked for any damage, and the ammunition within should be seated firmly and oriented the same way so the feed system can reliably bring the next round into the chamber. When rounds are properly seated and oriented, feeding is smooth and the risk of a jam or misfeed drops significantly. Other actions like adding optics or tampering with safety features aren’t part of this immediate safety and readiness check, and while secure storage of magazines matters, it doesn’t address the actual loading readiness.
