Understanding the trajectory of a 9mm bullet is crucial for safety, especially when shooting outdoors. While the initial drop point is one factor, several elements influence the total distance a bullet can travel. This analysis focuses on the various aspects affecting the range of a 9mm bullet and the importance of proper backstops.
The idea of using the point where a bullet initially hits the ground as the sole measure of safety is flawed. The angle of the gun at the time of firing significantly impacts the range. If the muzzle is elevated, the distance the bullet travels can increase dramatically, potentially exceeding 1.5 miles.
However, the most critical factor is the possibility of ricochets. A common misconception is that a bullet stops immediately upon hitting the ground. In reality, ricochets are frequent, and a 9mm bullet can travel a considerable distance after bouncing off a surface before coming to rest.

Having a backstop behind the target is vital. Depending solely on flat terrain to stop bullets is dangerous and could be considered criminally negligent if an incident occurs resulting in damage, injury, or death. A proper backstop absorbs the bullet’s energy, minimizing the risk of ricochets and uncontrolled travel.

If you intend to use flat terrain as a backstop, ensure sufficient downrange distance to accommodate the round’s maximum range, not just the initial impact point. While the original question’s phrasing is imprecise, if safety is the primary concern, approximately 1.6 miles of clear downrange distance is necessary when shooting a 9mm without a dedicated backstop beyond the natural terrain. This takes into account the maximum potential range under ideal conditions.
Therefore, prioritizing safety requires understanding the full potential range of a 9mm bullet, including the risks of elevation and ricochet, and implementing appropriate safety measures such as a reliable backstop.
