"So, smarty pants - what gun should I get?"

I receive many emails asking, in essence, what the "best" self-defense caliber might be. (Those emails, in fact, have served as the motivation behind this series.) The correspondents are probably expecting sage advice, the wisdom of years, a sort of Ballistic Oracle. What they get is a non-commital "it depends!"

If you take nothing else from this series, take this: there is no such thing as "best" - there is only "suitability for purpose."

Why is that? As we learned in the first parts, there is a pretty large envelope - caliber, weight, and velocity - of performance criteria that have shown themselves to work well. Thus, any cartridge you select within that envelope is likely to do the job, as long as you do yours.

That's the most important part: that the gun in question enables you to do your job. It is the first place you should start. You need to be honest with yourself, accurately assess what you can and cannot handle. Remember that a self-defense scenario often will call for multiple, rapid, precisely-placed shots. Can you do that with the guns that you're considering? Really? Be honest with yourself!

I see many people who are talked into a gun that is touted as a "better stopper", but who are unable to handle it to the standards given above. Most of this is technique, and technique can be learned, but everyone has some upper limit. Remember: only accurate hits count, and you should strive to maximize your hit potential. As we've explored, power is irrelevant if it doesn't get to something important!

Once you've passed that hurdle, the choices almost make themselves. In any given cartridge, if you pick a hollowpoint load in the middle of the caliber's normal weight range, you'll generally have most of what you need. There are exceptions, of course: at the lowest ends of the energy spectrum (say, standard .38 Specials) penetration becomes an issue, so you should tend to the heavier rounds. At the other end (the heavy magnums), the more powerful loads often need lighter bullets to limit penetration and enhance expansion.

For everything else, stay away from the lightest and heaviest bullets, pick a decent hollowpoint, and you'll most likely be just fine.

The most important part of this whole selection process is to practice with the load that you've chosen. If the cartridge/gun combination is "too much" for you to do so, that's a sign that you need to pick something else. You need to practice with your safety/rescue equipment, and if you can't or don't want to, then you will be less prepared to face a deadly encounter. The old trick of practicing with Specials while carrying Magnums on the street has been thoroughly discredited, because it doesn't allow the user to get used to the dramatic difference in handling between the two.

(This isn't to say that you have to do all your training this way; I do a lot of work with light loads when I'm diagnosing a trigger control issue, or to help develop a specific skill. When I've got them down, though, I switch to my carry load and train extensively with that.)

So, what do I carry? Most of the time, I load up the trusted and proven .38 Special +P 158 grain all lead semi-wadcutter hollowpoint. I've spoken with many people who have actually used this load against an adversary, and to a person they were all very satisfied with the ballistic effect. Massad Ayoob tells me that his research showed police agencies who switched from that load to hot autoloading cartridges did so not to get "better" bullets, but to get "more bullets." I'm confident in it's abilities, and in my ability to handle the cartridge from any gun under any conditions.

This is a tradeoff for me. For instance, I really like the .44 Special. It's a great round, but in a concealable gun I just don't handle it as well as other calibers. I'm honest with my limitations; increasing joint pain, particularly in my elbows, is beginning to limit what I can handle, which means that the sweet .44 Special is no longer a good choice for my primary caliber.

In fact, a hot .357 Magnum from a Ruger SP101 is easier for me to control than a .44 Special from a small gun, and the Magnum has become to be too much for me in a normal range session. I like the .357 too, but I have to admit to myself that if I want to live relatively pain free, I can't shoot it from my carry guns any more.

The result is that I've picked the most effective round that falls within my limitations, and practice with it extensively. I think that is the most rational way to approach this whole topic!

Next time, we'll explore some less obvious considerations when picking your "ideal" self defense cartridge.
