Home Defense Guns

Shotguns for Home Defense: The Traditional Choice

The 12-gauge pump-action shotgun has served as the standard home defense firearm for generations and for good reason. A single 12-gauge buckshot load delivers nine .33-caliber pellets simultaneously—more energy on target per trigger pull than any other common defensive platform. The Mossberg 500/590, Remington 870, and Mossberg Maverick 88 are the most proven pump-action options. Semi-automatic alternatives like the Mossberg 940 Pro and Benelli M4 add speed at a higher cost. The shotgun's primary advantage is terminal effectiveness at close range; its primary limitation is capacity (typically 4–8 rounds) and the manual dexterity required to operate a pump under stress. For a homeowner who wants maximum stopping power in a straightforward platform, the pump shotgun remains the benchmark.

AR-15 for Home Defense: The Modern Standard

The AR-15 has become the most popular home defense rifle platform for several well-supported reasons. The 5.56 NATO cartridge from a 16-inch barrel actually over-penetrates less than most handgun calibers through drywall—it fragments and decelerates rapidly in soft tissue and building materials, reducing pass-through risk compared to 9mm FMJ. The 30-round magazine means one reload handles most scenarios. Recoil is minimal, making accurate fast follow-up shots accessible to most shooters regardless of size or experience. An AR-15 with a quality red dot, weapon light, and sling is arguably the most effective home defense package available at any price point. The length of the rifle—typically 35 inches with a 16-inch barrel—can be a limitation in very tight interior spaces.

Pistol Caliber Carbines: The Compromise Platform

Pistol caliber carbines like the Ruger PC Carbine, Kel-Tec Sub-2000, and CMMG Banshee chamber pistol cartridges (9mm, .45 ACP) in a rifle-format body. They are quieter than rifle-caliber carbines, generate less felt recoil, and in many configurations accept the same magazines as your carry pistol. For homeowners in apartments or townhouses where over-penetration is a serious concern, a 9mm PCC with quality hollow-point ammunition offers a meaningful penetration advantage over both rifle calibers and standard handgun loads. The tradeoff is terminal performance at distance and stopping power compared to either a rifle or a purpose-designed defensive handgun.

Handguns for Home Defense: Flexibility First

A full-size or compact handgun has one advantage no long gun can match—you can carry it on your person throughout the day rather than leaving it staged in a single location. The Glock 17/19, Sig Sauer P320, and Smith & Wesson M&P are the most common home defense handguns. A 9mm +P hollow-point from a full-size handgun is a capable defensive load with decades of law enforcement track record. Handguns are also easier to maneuver in tight spaces and easier to retain in a close-quarters struggle than a long gun. For homeowners who also carry concealed, the same handgun staged at the bedside eliminates the need to train on two different manual of arms.

Home Defense Ammunition: What to Use

For shotguns, Federal FliteControl 00 buckshot is the standard recommendation—the FliteControl wad keeps the pellet pattern tight at home-defense distances, minimizing stray pellets. For AR-15s, Federal Fusion, Hornady TAP, or Speer Gold Dot in 55-grain or 62-grain provide reliable fragmentation performance. For 9mm handguns, Federal HST, Speer Gold Dot, and Hornady Critical Duty are the proven hollow-point loads. Avoid FMJ (full metal jacket) ammunition for all home defense applications—it over-penetrates walls and targets without expanding, reducing effectiveness and increasing pass-through risk.

Home Defense Setup: Lights, Optics, and Storage

A weapon-mounted light is the single most important accessory for any home defense firearm. You cannot legally or ethically shoot at a target you cannot identify, and most home intrusions happen at night. The Streamlight TLR-1 and SureFire X300 are the standard pistol and rifle light choices. For an AR-15, a 500-lumen weapon light paired with a red dot gives a complete close-range home defense package. Storage matters as much as the firearm itself—a quick-access biometric or push-button safe keeps the gun accessible to authorized users while securing it from children and casual access. Stage the firearm in a consistent location so you can access it under stress without searching.
