Self defense, stopping power, and caliber: Part 5

Posted by:

More energy can be a good thing – as long as it actually does something useful.

Last time we discussed the concept of the hollowpoint as a way to increase the frontal diameter of the bullet in the target. I also introduced the idea that it takes energy to expand the bullet, energy that is also needed to push the projectile into something that it needs to reach.

There is no such thing as a free lunch. If we want the bullet ...

Self defense, stopping power, and caliber: Part 4

Posted by:

The bullet is more important than the caliber.

We know that our bullet needs to do damage to whatever important thing it manages to find. How, exactly, is that going to occur? It just so happens that most animal tissue (including that of the violent felon who has just attacked you) is remarkably elastic, and consequently difficult to damage. Most tissues have a tendency to “close up” around puncture wounds, in the same way that they close up after a hypodermic ...

Self defense, stopping power, and caliber: Part 3

Once it gets there, it has to do work.

In today’s installment, we’re going to look at the second of the Twin Tasks:

2) The bullet has to do rapid and significant damage to that thing when it arrives.

It may not be self evident, but kinetic (moving) energy is either used or conserved (stored.) In the case of a bullet, it starts being used simply by fighting the friction caused by traveling through the air. Unless it encounters a target, the bullet ...

Self defense, stopping power, and caliber: Part 2

Posted by:

If it doesn’t get somewhere, it can’t do something.

OK, so we know about the Twin Tasks, the two things that a bullet has to do in order to stop an attacker:

1) It has to get to something the body finds immediately important, and
2) It has to do rapid and significant damage to that thing when it arrives.

Today we’ll be taking a look at Task #1: getting to something important.

Let’s start by pointing out that the user of the bullet ...

Self defense, stopping power, and caliber: Part 1 of a series.

Posted by:

I’ve gotten a bunch of emails recently regarding the choice of an appropriate self-defense handgun caliber and/or bullet. Around this one topic swirls more misinformation – and outright inanity – than any other I can think of. And now, here’s mine!

What follows is a layman’s understanding, backed by research of available literature and years of hunting and shooting experience, of the practical mechanics of wound ballistics. It is not intended to be a complete and exhaustive study of the subject. ...

A different (and old) approach to the backup revolver.

Posted by:

A gentleman wrote in asking about small backup revolvers – that is, a revolver to carry as a backup to a primary revolver.

I know that many people carry their primary gun on their hip, with a lightweight (aluminum, titanium, scandium) wheelgun in an ankle holster, and I know a couple of folks who carry a S&W “J” frame in a front pants pocket as a second gun.

This is not what the writer had in mind, though. He was thinking of ...

The case for the double action only revolver.

Posted by:

I endorse the practice of rendering defensive revolvers double action only (DAO.) Many people ask why, and I thought I’d give you my thoughts on the matter.

Let’s start with the usual argument for retaining single action capability, which I call the “Walter Mitty scenario”: the mythical need for making precise long range head shots. Let’s face it, folks – this just never happens in real life!

However, let’s say that you’re having a Jack Bauer kind of day ...

Yes, there are people who still think warning shots are a good idea. Don’t be one of them.

Posted by:

Xavier Thoughts chronicles the story of an elderly gentleman who, using his gun, confronted a burglar in his home. The outcome was that the perp got sent to jail. Great, right? Well, maybe not. This may get ugly when the inevitable civil suit is filed.

You see, the perp was injured because the homeowner fired an unaimed “warning shot” which fragmented and struck the intruder. As if that wasn’t bad enough in these litigious times, the gentleman couldn’t ...
