Home Defense Full-Size Pistols: Considerations, Characteristics & Examples

Home Defense Full-Size Pistols: Considerations, Characteristics, & Examples

The on-going debate is what gun makes the best home defense gun. A shotgun, rifle, and handgun each has advantages and disadvantages. Some choose one primary type with a different type as a backup. Most accept that a shotgun with appropriate ammo is usually the best primary choice, but even that is hotly debated. The same hot debate exists between a pistol and a revolver as best for home defense. And between 9mm, .40, .45, and 10mm calibers for home defense or 00 Buckshot or Birdshot, etc. There are a lot of critical personal considerations, in addition to the gun’s specifications and features and the ammo used, in deciding which gun for home defense. Out of the very many considerations (and training opportunities), below are just a few for you. Don’t forget consideration number 13.

Some considerations in making your home defense gun decision:

  1. who in the household might be using the gun,
  2. the familiarities and capabilities of those using the particular gun,
  3. the abilities for handling the recoil and muzzle flip for those possibly using it,
  4. the individual abilities and plans for reloading under stress,
  5. the abilities for using the gun with one hand (when holding child or flashlight, etc.),
  6. the location, easy storage, and retrieval of the gun (especially at nighttime),
  7. the cost of the gun & type of ammo (9mm has proven to be more controllable for our family),
  8. the type and grain/weight of ammo (strongly suggest HOLLOW POINT ammo- better expansion & less penetration properties), and necessary accessories,
  9. the design, levels, and layout of the home,
  10. the thickness and material of the home’s walls,
  11. the size of hallways and overall home and room sizes for maneuvering,
  12. the closeness of neighbors (for penetration and travel distance issues), and
  13. one hundred other important and personal preferences and factors.

Since there are so many personal factors, you must make your own decision based on your family members, home features, gun options, budget, and other key, specific variables. I want this article to stir your thoughts about this important matter, spur you to make some home defense gun decisions, and help you, by understanding some of my considerations and factors. Remember, whichever gun you choose, proper and SAFE training and practice with it in your home and environment are important, including an unloaded “dry run” of “what if” scenarios in your particular residence. Generally, handguns are the least powerful of rifle, shotgun, and handgun options. This can be a plus and/or a minus in home defense. Also, handguns usually require the most training, practice, and proficiency to use effectively inside the home. Practice. Practice. Practice.

Really, just about any compact or full-size pistol or revolver might be used effectively for home defense with modern contemporary ammo. Certainly, Night Sights are required for home defense and Sierra Hotel Tango Foxtrot encounters at nighttime. Also, Mini Reflex Red Dot sights and laser sights can work for effective home defense, IF (and a big IF) potential users of the gun are trained, familiar with them, and practice with them… and have some spare batteries on hand. IF you will do your part. Since I regularly practice, train, and teach handgun essentials as an instructor (and compete some) with realistic hands-on experience, I know that I have the foundation for using a pistol effectively for almost all intruder situations.

Reliability, accuracy, and familiarity with the chosen home defense pistol are key. That involves BOTH the human personal factor and the gun’s attributes. It is important to recognize that others in the household probably will also be involved in intruder situations and using the home defense gun, e.g. your spouse. Given our many unique considerations, my wife and I selected a full-size, semi-automatic pistol in 9mm for our home defense gun. (Note: In addition, one of us has a mild, felt recoil 20- gauge pump shotgun with a youth-size barrel for maneuverability loaded with #00 buckshot readily available.)

I am not prescribing these guns for your home defense, but given our shooting profiles, skills, preferences, medical conditions, home design, etc. these work best for us. Something for you to think about and determine for yourself. Maybe you prefer a revolver over a pistol, or a .45 caliber over the 9mm, or your EDC (Every Day Carry) compact carry pistol for home defense over a separate dedicated home defense pistol.

Your considerations and call!

In my article appearing here on January 23, 2014 titled “Handgun Attributes to Help Improve Accuracy,” I mention several physical characteristics that I look for in a home defense gun or any gun to help accuracy. I believe that there is a natural relationship between inherent accuracy and physical attributes of a gun, in addition to an individual’s contributions to accuracy. (Some debate this. But, for example, I believe that extra barrel length gives the bullet more twist in the barrel to build higher velocities before it exits. Also, that gun weight helps with muzzle flip and felt recoil.) I included them below in my definition of a home defense pistol, in addition to some other things.

For this article I am defining a home defense gun FOR US, my wife and me. Below, I have identified 7 physical characteristics present in our home defense pistol. These characteristics are summarized and drawn from my top 20 home defense 9mm pistol options which are below these characteristics. So our home defense 9mm pistol has these 7 CHARACTERISTICS:

  1. is FULL-SIZE with about a 5-inch barrel average (at least a 4.5″ barrel with a long sight radius);
  2. has a LARGE FRAME and OVERALL LENGTH of about 8.40 inches average (at least 7.70″ for longer Sight Radius);
  3. is a HEAVY-WEIGHT pistol (weighs on average about 32 ounces), lighter guns usually have more muzzle flip & felt recoil- which affects movement;
  4. has a CAPACITY of at least 9 rounds (for multiple intruders; having a large amount of ammo allows you to deal with a threat for a longer time before you must reload; etc.);
  5. has a short and soft TRIGGER PRESS (4 to 6.5 pounds);
  6. with a short and very identifiable RESET POINT & Travel Distance; and
  7. with 9mm CALIBER rounds that allow manageable FELT RECOIL with minimal movement.
