Having considered the first ten installments of this series–All the articles in this series may be found by entering “guns and liberty 2023” into the SMM homepage search bar–perhaps you’ve decided you prefer semiautomatics over revolvers, and want a compact semiautomatic pistol for daily concealed carry.  The next substantial question to be answered is: what caliber? Appropriate handguns are available in .380 ACP, 9mm, .40 S&W, .45ACP and a few other common calibers. Which is “best?” As the partial model chart from Glock (above)—solely in 9mm–-illustrates, there are many choices available from that manufacturer alone, including some with integral red dot sights, in all common handgun size categories—very concealable to full-sized duty handguns–and many, regardless of caliber, are quite close to the same compact size and weight.

Keep in mind that there is no such thing as a perfect gun or cartridge, a universally wonderful combination that works equally well for everyone, or that is so unquestionably superior it would be foolish to carry anything else.  While my daily carry gun is an easily concealed Glock 43X MOS augmented with a Crimson Trace RAD Micro green dot electronic sight (I’ll produce an article on that combination when this series is done) before that gun was invented, I carried a variety of handguns, including a Glock 19, a Glock 26, A Browning BDA .380, a S&W Model 59 (much modified), A much-modified 1911, a Colt Commander, a Browning Hi-Power, various Colt Pythons, a stainless steel Ruger Security Six in .357 Magnum (2.75” barrel), and even a Colt Detective Special (.38 Special), to name a few.  Even today I (very) occasionally carry a S&W Bodyguard in .380 ACP.

For a recurring security job, I carry the Glock 43X.  It is identical to the Glock 43 with one exception: a ten round—rather than six round–semi-staggered magazine, which makes the grip a bit longer and wider.  With two spare magazines I have 31 rounds, compared to 19 for a G43 with two spares, and in a weapon, like the G43,  suitable for daily carry.  I also carry the 43X because its slightly longer grip is easier to access from an inside the waistband holster–-I have large hands.


Cartridge choices for handguns are relatively simple.  For revolvers, the .38 Special and .357 Magnum predominate. One can also obtain revolvers in .44 Special, .44 Magnum and larger, much more powerful, specialized cartridges most commonly used for hunting, but for most people choosing a revolver, the choice is .38 Special or .357 Magnum.  The Federal .327 magnum, is another option, but that’s still not a widely known and used cartridge. The .357 is a .38 special with a slightly longer case, which allows more powder, greater bullet velocity, and therefore, more power—at the expense of a louder report, greater recoil and muzzle blast.  Both fire the same diameter and general weights of bullets.

How much more velocity and power? Gun News Daily.com provides a reasonably comprehensive comparison of contemporary cartridges.  Bullet velocity is commonly measured at the muzzle and is expressed in feet per second (FPS).  Bullet energy is expressed in foot pounds (FP).  The weight of bullets is expressed in grains. A 125 grain bullet weighs about .285 ounce.  As distance increases, velocity and energy decrease.

What do these numbers mean?  Generally speaking, the larger and heavier the bullet, and the faster it can be propelled, the better. This combination will generally result in the highest energy level, which generally results in the greatest potential “stopping power,” a subject I addressed in part in part 9 of this series.  However, keep in mind only rifle ammunition—and some shotgun shells–-has what might be considered true “stopping power,” and even that is subject to various caveats. The idea there is such a thing–-particularly in common handgun ammunition–-as a caliber or bullet configuration that will immediately end a deadly threat with a single impact is an iffy proposition.  Much depends upon bullet placement. All handgun ammunition is a compromise between potential effectiveness and the ability to carry a defensive weapon at all as rifles tend to be taxing to carry, and particularly to conceal.

What really matters—for the sake of comparison–is muzzle velocity and energy because very few gunfights take place beyond seven yards (most are much closer, in the area of 7 feet or less).  At such distances, very little velocity and energy is lost from the figures obtained at the muzzle.

Notice that the muzzle energy figures for the 9mm (+P: faster velocity, greater recoil and muzzle blast in this case) and the .45 ACP are similar–-the 9mm is higher–-but their velocity figures are quite different.  The 9mm+P obviously produces its energy through greater speed while the .45 does it via its much greater bullet weight.  At the same time, the .357 Magnum produces much greater muzzle energy and velocity which might lead us to believe it is far more effective than the 9mm or the .45, yet real world experience suggests the .45 is the superior “stopper” among the three.  The point is when it comes to stopping power with handguns, there is far more involved than just bullet weight, muzzle energy and velocity, though they are a useful–-if limited–-means of basic comparison.

Ruger LCR

Small revolvers like the Ruger LCR are designed for concealed carry. This revolver is produced in .22LR, .22WMR,  .38 Special, .327 Federal Magnum, .357 Magnum, and 9mm Luger. While any revolver chambered for .357 Magnum will also fire .38 special ammunition, the opposite is not true.

NOTE:  .38 special ammunition may be safely fired in revolvers chambered for .357 magnum, but .357 magnum may not safely be fired in revolvers chambered for .38 special ammunition.  Thankfully, the cylinders of .38 special revolvers are generally too short to chamber .357, but one should never fire ammunition in any weapon other than that specified by the manufacturer.

It’s reasonable to consider .38 special to be the smallest cartridge appropriate for self defense in revolvers.  Smaller calibers are available, but there is no real advantage in size or otherwise in such weapons.  Revolvers chambered for .357 magnum and larger calibers are themselves necessarily larger and heavier, often much larger and heavier, than smaller, short barreled revolvers chambered in .38 special.

S&W Model 637 “Airweight” .38 Special revolver

NOTE: small, light weight, short-barreled revolvers are essentially expert’s weapons.  Their long, heavy, double-action trigger pulls, small grips, and substantial report, muzzle flash and recoil make them difficult for inexperienced shooters to control, and actively painful to shoot more than a few rounds in a setting.

Common cartridge choices for semiautos are somewhat more numerous: .380 ACP (Automatic Colt Pistol), 9mm, .40 S&W (Smith & Wesson) and .45 ACP predominate. Again, there are a variety of other cartridges, but these are the primary four centerfire cartridges.  Of the four, the .40 S&W is the most recent, having been developed from the 10mm as a shorter cartridge with less energetic recoil characteristics.  Some years back, police agencies widely adopted the .40, but many have returned to the 9mm for less recoil and cost. The .40 S&W does approximate the performance of some .45 ACP ammunition with lighter bullet weights, while being small enough to use the same sizes of frames and slides as guns chambered in 9mm, though in some makes and models, the pressures generated by the .40 caliber round have produced some longevity issues when compared with the same weapon in 9mm.  Generally speaking, none of these cartridges is interchangeable.  Particularly with semiautos, one should load and fire only those cartridges for which a given handgun was designed. 

Ruger LCP-II

In this class, the .380 is generally considered the smallest cartridge effective for self-defense. It is true people have been stopped and killed by the common .22LR, but simply because it is possible to stop or kill an attacker with a .22 doesn’t mean it’s a wise choice of defensive ammunition. Even so, some new designs, such as Federal’s “Punch” .22LR are optimized for handgun use, and do appear to be more effective than previous rimfire rounds.

Handguns chambered for the .380, such as the polymer Ruger LCP, and the updated Ruger LCP-II can be very small and light indeed, but as with very small and light revolvers, tend to have mediocre sights and triggers (the trigger of the LCP-II is a significant improvement over the LCP) and because of their very light weight and small size, tend to impart considerable recoil energy to the shooter.  The muzzle flash and report of these weapons may also be—ahem–surprising.  These factors often result in mediocre accuracy.  Pistols like the LCP, with practice, are quite controllable, but they do have a rather sharp “bark” for the unwary or first time shooter., and a firm, correct grip is essential.

Cartridges are commonly named for their bullet diameter and developer, or to clearly differentiate them from similar cartridges.  The .357 Magnum, for instance, fires a bullet with a diameter of 357/1000 of an inch, and the “magnum” designation is intended to denote a more powerful version of the .38 Special, which fires a bullet of the same diameter.  The .357 gains its extra power from a slightly longer case, which allows slightly more gunpowder.  The .40 S&W fires a bullet of 400/1000 inch diameter, and major development work was done by Smith and Wesson.  It is essentially a development of the more powerful 10mm cartridge, but the case is slightly shorter to allow smaller framed weapons to fire it with less recoil and less long-term stress on the frame, slide and barrel.  The .40 S&W designation clearly differentiates it from 10mm ammunition, though both fire bullets of the same diameter and weight.  While it is possible to fire .40 S&W ammunition in a handgun chambered for 10mm, the opposite is not true, and again, always fire only that ammunition for which a gun is specifically chambered, particularly with semiautos.


For self-defense, hollow points have the greatest likelihood of expending more of their energy within a target–-thus having the maximum potential stopping effect–-and the least likelihood of over-penetration and ricochet as they will tend to “mushroom”—for the shape of the bullet when it comes to rest–-or fragment on impact with solid objects.  Full metal jacket, or “hardball” ammunition–-lead bullets fully encased with copper and with rounded noses–-are military issue due to international treaties and because of the military need for greater penetration of cover.

These are common 9mm cartridges. From right to left, is a Remington full metal jacket (FMJ) cartridge, a Remington jacketed hollow point (JHP) cartridge, and a Hornady “Critical Defense” cartridge—the cartridge I carry.  The red polymer insert in the hollow point cavity is designed to prevent clothing fibers from filling the cavity and preventing full expansion of the bullet.

NOTE: .380 and 9mm cartridges were popular in Europe long before they gained widespread acceptance in America.

In the military context, it is often better to wound than to kill an enemy.  Theoretically, a wounded enemy takes three people out of the fight, at least temporarily: the wounded soldier and two others to tend and carry him, but the need to immediately stop a criminal attacker is a very different matter.  FMJ ammunition is entirely appropriate–-and usually much cheaper–-for practice, but not for daily carry, as it tends to be a less effective stopper, and often over-penetrates, especially in “fast” cartridges like the 9mm.

NOTE: Some of our more recent enemies do not share our determination to leave no man behind on the battlefield, nor do they universally try to medically evacuate their wounded or recover their bodies.  This may eventually factor into ammunition design for our military.  It seems rather pointless to fret over the potential damage done to an enemy by a hollow point pistol or rifle bullet when we’re simultaneously shooting them with cannon from rotary and fixed wing aircraft, or blowing them apart with grenades, mortars, artillery or missiles launched from drones that actually tear them limb from limb or reduce them to atoms.

Hollow point ammunition is duty ammo, ammunition intended for serious, defensive purposes, not training or target practice. Training/practice ammunition is best suited for training.  Cost is also a significant factor.  50 rounds of Magtech 115 grain full metal jacket 9mm cartridges sells for $17.99 at Midway USA, which 25 rounds of Hornady Critical Defense 115 grain jacketed hollow point ammunition sells for $29.99, or $59.98 for 50.

Practice cartridges, whether with lead bullets or jacketed bullets, generally do not use hollow point bullets, and are therefore generally substantially cheaper than carry/duty ammo, however, it is often of lower power and will therefore have somewhat different recoil, report and muzzle flash characteristics than carry ammo.  Carry ammo will also likely shoot to a slightly different point of aim than practice ammo. Some light-loaded practice/target ammunition may cause malfunctions in some semiautos.  This is so because their springs must be designed to function with more powerful carry ammunition.  The lesson is to occasionally practice with the ammunition one intends to carry.  How often?  Perhaps once a year as a means of clearing the old inventory prior to buying new rounds.  While modern ammunition properly stored may remain functional for a lifetime, it’s a good idea to regularly rotate one’s carry ammunition. And yes, I know carry ammo may be hard to find and expensive these days, but we do what we can.

NOTE:  A malfunction is a stoppage that can be quickly–-mere seconds–-cleared by hand and the firearm restored to firing status.  A jam is a stoppage that requires tools–-and time–-to resolve, usually because of damaged or broken parts.  Unlike what many think, revolvers do malfunction and jam.

Another significant issue is ammunition cost. If you’re going to be truly proficient, if you’re going to have the confidence that will help to ensure you’ll likely be able to avoid having to use a handgun, which should be your preferred outcome, or when you do, you’ll be able to efficiently solve the problem, you must practice, and practice correctly, regularly.  Anyone can learn to shoot, but shooting well under pressure is an acquired skill, and a skill degraded without consistent, correct practice. And then there is ammunition availability, or the lack thereof.  Circa Winter, 2023, ammo is generally more available nationwide, but this may be hard to follow advice.  One may not be able to practice with inexpensive .22LR ammo, because it could be as hard to find as any other caliber.  I doubt shortages will be resolved this year, perhaps not the next, but it’s a worthy, if hopelessly optimistic goal to keep in mind as you read what follows.

HINT: dry firing—practicing aiming and trigger control without ammunition, has long been proved to improve marksmanship and confidence, perhaps even as much as firing live ammunition. With semiautos, this also involves cycling the slide for each trigger press, which, if done correctly, builds vital muscle memory. Go here for an article about how to do it correctly.

All of the ammunition that follows was priced in lots of 1000.  This may sound like a great deal of ammunition, but when learning to shoot–-particularly if one attends professional schools–-this amount of ammo can easily be consumed within a single day.  Revolver cartridges and the .380 can be sometimes harder to find in 1000 round lots, but when purchased in that quantity, one can usually save over the per-box price.  The prices listed are, circa March, 2023, close to those of other brands currently for sale on the ammo market.  Hollow point ammunition suitable for concealed carry normally comes in 50 round boxes, but every manufacturer markets ammunition claimed to be nothing short of miraculous–-such as Hornady’s Critical Defense cartridges–-in 20 to 25 round boxes at much higher prices.

In revolvers, .38 special ammo is generally cheaper than .357 ammo of the same bullet configuration, and this is particularly true for ammo employing lead bullets. Be aware, however, that .357 practice ammo with lead bullets is infamous for leaving significant amounts of lead fouling in revolver barrels, requiring time, tools and dedication to remove (too much fouling degrades accuracy and can actually be dangerous). Copper jacketed bullets tend not to have this problem, or at least, to a much lesser degree. In semiautos, 9mm ammo is generally much cheaper than the other three most common types and is generally much more readily available.  Interestingly, .380 ACP, though using less brass and lighter bullets, is substantially more expensive that the larger, more powerful 9mm cartridge, probably because less is made in response to less demand compared with the 9mm.

The listed ammo prices come from the Midway USA site, a popular supplier of ammunition and all things gun.  I’ve found them uniformly excellent to work with.  Their web site can be found here. Keep in mind ammunition prices can vary considerably from place to place. Two additional good places to find ammo are Lucky Gunner, and Ammo.com.  One might find ammunition that appears to be cheaper online, but with shipping costs, and carriers such as Federal Express adding $25.00 or more for handling ammo, ammo found locally may end up being no more expensive after all.  However, online retailers may well have ammunition one can’t find locally.  Not terribly long ago, local dealers were happy to special order ammo in case–1000 round–lots, but no one can count on that kind of service anymore, and case lots might be only found online.

NOTE:  During the Obama era, ammo costs were astronomical, and many common rounds were scarce, forcing rationing on retailers and consumers.  This trend reversed during the first three years of the Trump Administration, and ammo was once again plentiful and back to normal price levels.  However, with the Coronavirus, and the election of the Biden Meat Puppet Administration, common calibers were again scarce, prices increased, and rationing, when ammo was available, was common.  Ammo in these quantities was difficult to impossible to find anywhere, and prices were generally somewhat to obscenely higher for ammunition one couldn’t find but again, the relative prices are useful as a point of comparison.  Circa March, 2023, ammo is easier to find, somewhat less expensive, and rationing is less common. However, it’s still difficult in many places to find sufficient quantities of less common cartridges. With President Biden promising to ban “assault weapons,” and pretty much everything else “come hell or high water,”  supplies may again tighten, prices rise, and sales of guns and ammo continue to set records.

Legend: LRN: Lead Round Nose.  FMJ: Full Metal Jacket—the bullet is round nosed and fully encased in a copper jacket.  LRN: Lead Round Nose–the round nosed bullet is made entirely of lead (usually an alloy containing mostly lead).  Bullet weights are expressed in grains.  All are listed in 1000 round case lots.  All have fully reloadable brass.

Magtech .38 Special, 158 Gr. LRN, $513.99

Magtech .357 Magnum, 158 gr. FMJ, $825.99

Magtech .380 ACP, 95 gr. FMJ, $519.80

Magtech 9mm, 124 grain FMJ, $341.99

Magtech .40 S&W, 180 gr. FMJ, $499.80

Remington UMC .45 ACP, 230 gr. FMJ RN, $654.99 (I couldn’t find any Magtech ammo in this caliber/bullet configuration)

Notice .45 and .357 ammunition are by far more expensive than the other common calibers, while 9mm remains relatively inexpensive in comparison.

Note too 500 rounds of Remington Thunderbolt .22LR ammunition–-and there are many models chambered for this caliber in revolvers and semiautos–-could be had in early 2020 for about $27.00.  Now, it’s $41.49 at Midway, and as this is written, is available.

NOTE:  Every one of the cartridges I’ve just listed is currently in stock at Midway USA. The prices are down from last year, even for .357, but are still, historically, high.  At least ammunition is now available in most places. Elections, and election fraud, matter.

Glock 44 with Crimson Trace laser sight

The .22LR is an important, standard cartridge, and few even moderately serious shooters do not have at least one gun chambered for it. Hopefully, as supply once again catches up with demand, it will once again be easy to find.  Remember however, .22LR is not a good choice for a self-defense arm, though for a backup gun to be used only at near contact range as a last resort if a primary arm is lost or out of ammunition (an article on just such a weapon is available here), it is a reasonable choice, and .22 LR is much better than nothing.

The .22LR remains a very versatile cartridge and no shooter should be without at least one .22LR rifle, and arguably, a .22LR handgun—Glock finally produced a .22LR handgun, the G44. My article on that handgun is available here.

Kel Tec P17

That said, Kel Tec has produced the P17, a .22 LR handgun with 17 round capacity—16 round magazines and one in the chamber. Though small and light, it has an excellent trigger, fiber optic front sight, and ships with three magazines, all at a MSRP of $199.00. It is a fine practice handgun, and with 17 round capacity and a 3.8” barrel, might reasonably serve for self-defense with the right ammo.

Kel Tec CP33 with Vortex Crossfire red dot sight

Just for fun, my article on an unusual–highly accurate and enormously fun– .22LR handgun, the Kel Tec CP33 is available here.  Its magazine capacity is an actual 33 rounds!  It’s obviously not a wise choice for concealed carry, but Kel Tec makes interesting and innovative firearms.

New Factory Ammunition Alternatives:

The ammunition about which I’ve been speaking to this point is factory loaded with all new components.  A reasonable amount of money can be saved with factory-reloaded–-usually marketed as “remanufactured”–-ammunition.  Such ammunition is usually loaded with once fired (and properly cleaned and resized) brass and usually less expensive bullets.  This allows a manufacturer to provide a line of quality ammunition at reasonable prices, particularly when compared with their top of the line defensive ammunition.

Such ammunition is virtually always reliable, however, it is a good idea to use nothing but first quality ammunition loaded with all new components in a firearm upon which you depend for your safety.  Reloaded ammunition is easier to get these days; but bullets, powder, and particularly primers, tend to go to manufacturer’s standard lines.

One might be able to save money by reloading ammunition, which for many people is enjoyable, a sort of Zen experience.  Once the necessary equipment has been purchased, the price per round can be lower than even remanufactured ammunition, but this is true only if one shoots and reloads a great deal. In the first years of the age of Trump, the availability of brass, bullets, powder and primers was no longer an issue, and prices were reasonable, but again, all of these components, particularly primers, in the era of Biden, or whoever his handlers are, are difficult to impossible to find and far more expensive than usual, on the order of $100 dollars per thousand.  Ammunition manufacturers also make and market primers, but their production is being used almost exclusively in their products, leaving little or nothing for the reloading market.

Absent buying a progressive or automated reloading system, reloading is labor intensive and time consuming.  By that I don’t mean it takes a great amount of strength, but it is repetitious.  Obviously, it requires consistent focus and attention to detail, for one is essentially making one cartridge at a time and must make each perfectly.  Many experienced shooters buy their handgun practice ammunition in bulk and reload only specific, larger rifle cartridges, taking great time and care, and more precise than usual tools, to produce the most accurate ammunition possible, which is one of the advantages of hand loading.

Why is ammunition so scarce and expensive?  There is no evidence to support the various conspiracy theories, though our current federal government, and about half the state governments, would love to disarm us; it is a simple matter of supply and demand.  All the manufacturers have pulled out the stops to increase production, and there is at least one entirely new manufacturer coming on line in 2023, all of which should help.

With D/S/Cs in political control, the summer of love, defund the police, Antifa, Black Lives Matter, and police officers across the country doing only what is absolutely necessary to avoid being fired—the Ferguson Effect–sued or imprisoned, millions of Americans of all political beliefs have come to understand where the defense of self and those we love is concerned, we’re on our own, and we always have been.  Demand for firearms, and ammunition, is the primary cause of the shortage.  The other factors I’ve mentioned are driving demand.

The next article will cover the primary factors to be considered in choosing a caliber/handgun. I hope to see you next Tuesday.
