There are three primary firearm choices for home defense, each has inherent strengths and weaknesses, when looking at a weapon for home defense what are our needs and how are they achieved. When you are shooting someone in self defense you are looking to stop the threat and that can be accomplished with a single shot from a .22 or it can take multiple shots from a rifle, there is no magic caliber or weapon that will guaranty stopping an intruder with a single shot. When someone is shot the body has ways of dealing with the injury. Unless there is a hit to the central nervous system instant incapacitation isn’t likely to stop a determined intruder.
First I will look at handguns
Pros
- convenient
- Small
- Light
- maneuverable
Cons
- lack power
- difficult to shoot well
- penetration (excessive)
Handguns seem to be the weapon people seem to think of first when they think of home defense, be it a revolver or a semi-auto pistol , they are small don’t take up a lot of room and are very maneuverable and have stopped many an intruder. The problem I find with handguns is there is a learning curve required to shoot one well. Case in point is my brother we spent many days at the range getting him so he could hit an 8” plate at 15’ there was a lot of ammunition put through that weapon when he finally gave up on handguns in general. Another factor is you will not necessarily be the only one to use that gun for defense. What if your significant other who hasn’t had the chance to practice with the firearm needs to use it?
Next let’s look at shotguns
Pros
- larger wound
- simple to fire
- penetration (walls)
Cons
- Difficult to maneuver
- storage
- requires two hands
Shotguns are normally considered a close range weapon, when shooting at most self defense ranges the shotgun with a 18” barrel is going to have a group about the size of a softball to as large as maybe a basketball in some McMansions if you can put 8 .32 caliber bullets into someone at once you will have done a tremendous amount of damage. Long guns in general are easier to learn to shoot accurately but on the down side they can be tough to maneuver, storage can be a problem and it is tough to use one handed. Another downside is smaller framed people may have a fear of using a “big” shotgun.
Finally let’s look at Rifles (carbines specifically)
Pros
- Power
- large wound
- penetration
Cons
- Difficult to maneuver
- storage
- requires two hands
It has been said if you are going to a gun fight bring a rifle! Rifles are powerful, accurate and easy to use since the down side of a rifle is similar to that of a shotgun I will focus on the pro side of things. The wound created by a rifle is remarkable. I find it amazing at how much damage a little projectile traveling fast can do. I have taken numerous deer with .44 magnum, shotgun and rifle and for pure killing power the rifle wins hands down, despite being a similar projectile to the handgun the penetration can be controlled with proper selection of ammo (this is the case with both handguns and shotguns as well) on top of that due to the velocity of the round they tend to break up easier that the slower moving pistol or shotgun rounds.
Hopefully this will give you some insight in choosing a home defense weapon. Ultimately it will and should come down to what you can shoot well and what you are comfortable with. I have a 12ga locked next to my bed and a .45 either on me or in my nightstand drawer. If I need to barricade myself in my room I will be using the shotgun and the bride will too. If I need to go looking for a prowler the handgun is quick and easy, and if I expect a standoff with zombies I am breaking out the carbine, the choice is yours but don’t choose a weapon just because it is what one person chooses to use after all it is your life in your hands.
