Quick Answer
An ideal home defense firearm should be reliable, controllable, and effective at close ranges. It should be chambered in a self-defense caliber with sufficient stopping power, and have sufficient magazine capacity for the situation. A firearm with a reliable trigger and durable construction is also essential.
Caliber and Stopping Power
When it comes to stopping power, 9x19mm Parabellum and .40 S&W are popular choices for home defense. However, the .45 ACP is often preferred for its larger diameter and increased stopping power. For those who prefer a smaller caliber, the 9x19mm Parabellum with a +P or +P+ load can provide sufficient stopping power. A minimum of 12 rounds of ammunition is recommended for home defense.
Firearm Design and Reliability
A reliable home defense firearm should have a double-action only (DAO) or striker-fired trigger to prevent accidental discharge. A firearm with a Picatinny rail or similar mounting system can also allow for the addition of a flashlight or laser sight for improved target acquisition. The firearm should also have a durable construction and a minimum of a 3-year warranty.
Magazine Capacity and Control
A minimum of 12 rounds of ammunition is recommended for home defense. This can be achieved with a standard capacity magazine or one with an extended capacity. To control the firearm, a grip with a aggressive texture and a comfortable size is recommended. This will allow the user to maintain a firm grip on the firearm, even in high-stress situations.
