Caliber for Self Defense Handgun

What Caliber for a Self Defense Handgun

Handgun_gel_comparison

 

When we look for a self defense handgun caliber our goal is to choose the caliber that inflicts the maximum amount of damage to the threat.  Although the topic of harming, potentially killing, another human being is uncomfortable to many you do not want to be wondering if you picked the best caliber for self defense when you are defending yourself or your family.

 

When we look at calibers for self defense we must narrow down our options.  In terms of handgun calibers we view .380 through 10mm as viable self defense handgun calibers.  Of those viable calibers we state that .380 through 45acp are acceptable calibers.  Of these acceptable calibers we know through medical research that there is negligible difference is damage caused by these projectiles.

 

We recommend 9mm for self defense due to its ability to inflict the maximum damage to our threat.  This is because 9mm offers higher capacity and less recoil when compared to other acceptable self defense calibers and because the 9mm allows the user to fire more rounds faster and more accurately it offers a high wounding capacity.  9mm is also cheaper than the other acceptable self defense calibers, which, means more practice and training for less.

Defensive Handguns

What makes a good self defense handgun?

 

When we look for a self defense handgun we look for handguns that have a few common characteristics.  These common characteristics are that the handguns is simple and efficient, reliable, light short and consistent trigger pull, and a lower bore axis.

Handguns that have these characteristics generally fall into the category of Modern Striker Fired (MSF) handguns.  Examples of MSF handguns are Glocks, the Smith and Wesson M&P line and Springfield XD and the XDm series.

The MSF handguns listed above are recommended due to the fact that they are simply and efficient.  This means that the handguns are lacking external and manual safeties.  Trigger safeties are considered passive safeties and would not be included considered inefficient because they are naturally deactivated when firing the handgun.

These handguns are also considered highly reliable through years of testing and vetting.

The MSF handguns are also recommended as a self defense handgun due to the fact that they have a light, short and consistent trigger pull.  The common trigger pull, or the amount of pressure that is required to fire the handgun, is 5.50 lbs.  Unlike single/double action handguns that require the user to master two different trigger pulls, one short and light, and one heavy and long the MSF handgun has only one trigger pull.

The last common characteristic we look for in a self defense handgun is a low bore axis.  This means that the bore of the handgun is as close as possible to the users hand.  This allow the user to manage recoil as efficiently as possible.

 

Another characteristic that we look for t is that the handgun be chambered in 9mm.  We will discuss the choice of 9mm as a defensive caliber in a later post.
