Selecting appropriate cartridges for a Glock 19 intended for personal protection involves careful consideration of various factors. Effective self-defense ammunition should reliably cycle in the firearm, offer sufficient stopping power, and limit overpenetration. Common choices include jacketed hollow points (JHP) designed for expansion upon impact and controlled fragmentation, enhancing energy transfer to the target while minimizing risks to bystanders. For example, some manufacturers design projectiles specifically to perform optimally within the velocity range typical of a Glock 19’s barrel length.
The significance of ammunition choice for self-defense stems from the ethical and legal responsibility to minimize collateral damage while ensuring effective threat neutralization. Historically, full metal jacket (FMJ) rounds were standard, but advancements in bullet technology led to the development of specialized self-defense projectiles. These modern options offer a balance between stopping power and reduced overpenetration, aligning with the principles of responsible firearm ownership.
