The Best 9MM Ammo in 2024 For Self Defense

I’m going to go deep into the best 9mm ammo here, but you may just want my picks and move on. So I have summarized the picks here, but I hope you’ll dig in to understand why.

	Buffalo Bore +P+ JHP	$
	PolyCase 9MM +P ARX Inceptor	$
	Hornady‘s XTP +P JHP	$
	Underwood 9mm Xtreme Defender +P+ (Penetrator)	$
	Federal HSTs	$$

	Corbon PowRballs	$$

I’ve been a handgun enthusiast for a little over a decade now, and I love everything about handguns. I love older pistol designs and all modern designs the same way. I have my preferences as far as handguns designs, i.e. I like hammer-fired handguns better than striker-fired ones, I like handguns with an all-steel frame better than those with a polymer or an alloy frame, and I like 1911s and SA/DA magnum revolvers far more than I’d ever like any other handgun platform.

My Favorite Handgun Calibers

Likewise for handgun calibers, not counting rounds I consider obscure but slowly gaining popularity (e.g. 10mm, .460 Rowland), I have a soft spot for both the .45 acp and the .357 magnum — which shouldn’t come as a surprise to anyone because like I said, I love 1911s and magnum revolvers. For me, as far as handgun calibers, these two being on the higher end of the ballistics performance spectrum, no other calibers come close.

The .45 ACP might be the slowest and heaviest of the “big three” semi-auto handgun calibers, but it makes the biggest holes in soft tissue targets when comparing FMJ vs. FMJ or JHP vs. JHP — its only downsides: terrible solid target penetration (slow and fat bullets have a hard time penetrating even entry-level body armors) and lackluster ammo capacity in handguns chambered for it (the typical 1911 magazine can only fit seven to eight of these big fat cartridges).

Do You Feel Lucky?

The .357 magnum on the other hand is the complete opposite of the .45 acp. A lighter bullet with a smaller cross sectional circumference propelled to velocities a couple hundred feet per second faster than the speed of sound, this handgun caliber is unrivaled when it comes to penetration, so much so that it will overpenetrate soft tissue targets — but that can easily be mitigated by using soft jacketed hollow point (SJHP) or jacketed soft point (JSP) bullets.

Its only downside: lackluster ammo capacity. Typical small frame revolvers can only hold five rounds, medium frame revolvers can only hold six to seven, and large frame revolvers can only hold up to eight. Not saying that wheelguns are worse than semi-autos, if anything I feel safer knowing that I can store and access mine in a pinch, like in my car or nightstand.

So as much as I hate to say it, my two favorite handgun calibers have the same Achilles’ heel: the handguns they’re chambered for can’t carry as many rounds as I’d like.

Why the 9×19 Parabellum is a great option

Just because I said I prefer the two handgun calibers I mentioned above doesn’t mean I think the 9mm is no good. In fact, I like it a lot (just not nearly as much as I like the other two). I don’t buy into the whole .45 acp vs. 9mm debate, because I don’t see the point. Why do I have to choose one over the other when I can have both?

The 9mm will not create as big a hole as the .45 acp does, and it will never outrun a speeding .357 magnum bullet fired from a 4-inch-barrel revolver, so as far as ballistics, it will never come close to my two preferred handgun calibers. But it offers one thing neither of my preferred calibers offer: superb ammo capacity.

9MM Ammo Capacity

Case in point, a full-size Glock 17 can hold 17 rounds of 9mm in the mag, while a Glock 21 (which is about the same size as a Glock 17) can only hold 13 rounds of .45 acp.

I wouldn’t bother comparing ammo capacities between shooting platforms for the .357 magnum and the 9mm, as I see no point in comparing revolvers to semi-autos.

But if pushed to it, comparing single stack semi-autos, a single stack 1911 in 9mm can hold up to ten rounds, while both the long-defunct LAR Grizzly and the recently-revived Coonan 1911-style pistols chambered for the .357 magnum can only hold seven rounds.

And don’t even get me started on modern 9mm handgun designs with wider frames that allow for double-stack magazines. I can go on all day.

9MM Ammo Wins in Capacity

So the 9mm trumps both my preferred handgun calibers in the ammo capacity department. What about its downsides?

Well, there are 9mm ammo extreme pressures loads (i.e. those with the +P+ designation) which, while a full 100 fps slower compared to entry level .357 magnum velocities, are up the same super sonic alley, making it vastly superior to the .45 acp whenever there’s need for more penetration.

And with modern bullet designs such as expanding full metal jackets (EFMJs), jacketed hollow points (JHPs), etc., the lighter and faster 9mm can rival the slower and heavier .45 acp in the terms of wounding capabilities.

With all the 9mm ammo choices on the market though, we’re presented with another problem.

Which 9MM ammo do we pick for self defense?

The perfect self defense load for handguns, regardless of the caliber, must provide penetration depths of 12 inches minimum and 18 inches maximum. At least these are the numbers the FBI go by.

Fortunately for us, since the FBI already did the research, we can use this metric to help us determine which ammo to pick. But we’ll add a few more metrics of our own: muzzle energy, wounding capability (the bigger the permanent and temporary wound cavities, the better) and pricing.

So to narrow down the ever-growing list of 9mm ammo options for self defense, we’ll be comparing offerings from different manufacturers based on the bullets’ ability to penetrate only within 12 to 18 inches (those that penetrate less than 12 or over 18 inches will have to be weeded out), how they perform in ballistics gel tests, and how much each costs.

Info were gathered from several YouTube videos uploaded by tnoutdoors9, ShootingTheBull410 and ScubaOz, ammunition manufacturer websites, third party websites such as LuckyGunner and online gun forums. The research took a few days to make sure we only provide the most accurate data possible.

To help our readers make sense of the table above, we’ve created a few 9mm ammo graphs.

9MM Ballistics Analysis

The chart below specifies each brand’s ballistic performance factoring in bullet weight and velocity:

9mm Bullet Weight

The red bars on the bar graph above represent each bullet’s weight in grains.

 A heavier bullet penetrates barriers better, and when it hits a bone in the body, causes the bone to fracture and splinter. The bone fragments shooting in all directions in turn result in more tissue damage.

But the problem with heavier bullets (in 9mm cartridges at least) is they can be harder to push with the limited room the cartridge provides for powder — in simpler terms, a heavier bullet will move slower compared to a lighter bullet. This is why the heaviest 9mm bullets only weigh 147 grains. In addition, heavier bullets tend to have more felt recoil.

Five of the contenders, Federal Premium HST JHP, Speer Gold Dot +P “Short Barrel” JHP, Hornady XTP +P JHP, Winchester PDX1 Defender +P and Buffalo Bore +P+ JHP all weigh 124 grains. While these will have no problem breaking bones, these bullets will be significantly slower compared to the lighter and faster options like the PolyCase ARX Inceptor +P and the Underwood 9mm Xtreme Defender +P+.

Actual Velocity vs. Advertised Velocity

The green bars on the bar graph above represent each bullet’s velocity in feet per second. These are actual velocity figures when bullets are fired from a 4-inch barrel — not the velocity figures printed on the box of each of the brands.

A higher velocity equates to more energy which results to better ballistic performance. But like weight, a higher velocity also has the same downside: more felt recoil.

The fastest of all the bullets we gathered info on is PolyCase ARX Inceptor +P, which is understandably so, because it is also the lightest. Underwood 9mm Xtreme Defender +P+ is the second fastest, while Corbon PowRbal +P is the third.

9MM Ammo and Muzzle Energy

The yellow bars on the bar graph above represent each bullet’s energy in foot-pounds of force (ft.lbf) at the muzzle. Since we’re using actual velocity figures when bullets are fired from a 4-inch barrel, these are also the actual energy figures, not to be confused with those printed on bullet packaging.

It’s a no-brainer that a higher muzzle energy equates to better performance. The consensus among firearms enthusiast is, when a high energy FMJ bullet hits a soft target, the energy is just wasted because the bullet won’t stop until it travels too far or it hits another target. But with designs such as modern day hollow points and fluted bullets, the energy is not wasted as the bullet can utilize it to cause more tissue destruction.

So for the purposes of this analysis, since we’re not including FMJs, the higher muzzle energy a bullet has, the better it will be as a self defense option.

9MM Energy Winner

Among the bullets we analyzed, the one with the highest energy is the Bufallo Bore +P+ JHP. It’s among the heavier bullets but it has a 1,300 feet per second velocity, only 1 grain and 50fps short of typical entry level .357 magnum loads.

In second place comes Underwood 9mm Xtreme Defender +P+, and Corbon PowRbal +P comes in at third.

9MM Ammo Terminal Performance

The graph below gives an idea how each of the bullets dump their energy in a soft target.

These results are in no way scientific because the type and measurement of wound cavities can be highly variable depending on a few factors such as the target’s stature and clothing, not to mention these results were taken by firing each bullet from a 4-inch barrel at a soft medium (10% ballistic gelatin – as dense as human flesh but behaves and reacts differently when hit by a speeding bullet) without accounting for bone hits and measuring only the widest visible disruption caused by the bullet (in inches).

So as a disclaimer, take these results with a grain of salt. In a gunfight, it’s not the guy who uses the super awesome bullet design that wins, but the guy who can place well-aimed shots at the right time.

Still, these results are a good indicator of how well a bullet would dump its energy in human tissue. Assuming you do your job, the bullet that will give you the best chances of incapacitating your bad guy quickly is Underwood’s Xtreme Defender +P+. The PolyCase ARX Inceptor +P comes in as a close second, and the Buffalo Bore JHP +P+ comes in third.

9mm Soft Tissue Penetration

As we briefly touched upon, the FBI adheres to a specific standard for handgun bullet penetration.

A bullet has to penetrate at least 12 inches minimum and only up to 18 inches maximum when fired in 10% ballistic gel. The 12-inch minimum is required to make sure that it will penetrate deep enough to cause damage, while the 18-inch maximum is required so that it will not overpenetrate to the point that innocent bystanders might get hit.

The chart below shows the bullets’ minimum and maximum depth of penetration measured in inches:

The blue bars represent the minimum depth (measured in inches) of ballistic gel material each bullet penetrated, while the orange bar represents each bullet’s maximum penetration depth.

Unlike the previous chart listing the somewhat variable terminal performance of each bullet (i.e. wounding capability), these penetration tests can be repeated by simply shooting each bullet in 10% bare ballistic gelatin. It is therefore scientific and reliable.

No Collateral Damage

When shopping for 9mm ammo that will penetrate enough to only cause damage in the bad guy and not cause any collateral damage, we think the Hornady XTP +P comes out on top, the PolyCase ARX Inceptor +P again comes as a close second, and the Buffalo Bore +P+ JHP again comes as a close third.

Unfortunately we’ll have to weed out the only over-penetrating contender when considering this metric (i.e. if you’re sure you won’t have to shoot a bad guy through a solid barrier) — Underwood’s Xtreme Defender +P+. In several tests it has been shown to always penetrate a couple of inches over the FBI’s 18-inch penetration limit.

And this means we’ll have to remove the under-penetrating bullets as well. Lehigh Defense Maximum Expansion JHP, Speer Gold Dot +P “Short Barrel” and Corbon PowRball +P all have to be taken out of the list.

9MM Ammo Price

Of course, what’s the point in crunching all these numbers and determining that brand X is better than all the other brands when you don’t have enough moolah to buy it? All this Mathcraft is useless if your handgun’s mag is empty, yes? The chart below shows how the different offerings stack against each other so we know which ones are wallet-friendly.

As can be quickly surmised from the chart, Hornady XTP +P is THE most affordable brand, while Corbon PowRball +P comes as a distant second and Winchester PDX1 Defender +P comes as an even more distant third.

So Which 9MM Ammo Should You Pick?

Yeah, it gets confusing when you have to factor in a bullet’s ballistic and terminal performance, its effectiveness to penetrate just enough to disembowel a bad guy, and its price.

So, to make the comparison as fair to all contenders as possible, each bullet will be ranked from 1 to 9 depending on each of the metrics used, and all scores will be added up and divided by the number of metrics used.

The table below shows how each bullet was ranked in the different metrics we used:

	Brand	Weight Rank	Velocity Rank	Energy Rank	Minimum Penetration Rank	Maximum Penetration Rank	Wounding Capability Rank	Price Rank
	Lehigh Defense 9mm Maximum Expansion JHP	8	5	6	0	6	5	2
	PolyCase 9MM +P ARX Inceptor	5	9	7	8	8	8	5
	Underwood 9mm Xtreme Defender +P+ (Penetrator)	6	8	8	9	0	9	3
	Buffalo Bore +P+ JHP	9	6	9	7	7	7	4
	Corbon PowRball 9mm +P	7	7	8	0	0	5	8
	Federal Premium HST JHP	9	3	5	7	7	4	3
	Speer Gold Dot +P "Short Barrel" JHP	9	4	6	0	7	5	6
	Hornady XTP +P JHP	9	2	4	8	9	6	9
	Winchester PDX1 Defender +P	9	4	7	7	6	5	7

And here are the results:

Best 9MM Ammo Recommendations

As far as I’m concerned, PolyCase ARX Inceptor +P, Buffalo Bore JHP +P+ and Hornady XTP JHP +P are tied for first place. Each bullet is designed differently — Polycase uses a more recent fluted design while Buffalo Bore and Hornady use classic jacketed hollow points.

Of these three, I would choose the Buffalo Bore JHP +P+ simply because I just love Buffalo Bore. While they’re involved in a personal injury case with Glock and Cabela’s right now, I’ve always had a soft spot in my heart for their loads.

A small ammunition company (which makes them an underdog) known for offering some of the hottest factory loads on the market, Buffalo Bore has been around for a while (can’t find anything on them thru Google, the first time I heard about them was in 2008 when I read an article about the .460 Rowland) but I believe they were founded by Tim Sundles — a hunter who has a passion for super hot handloads. Like most simple folk, I like rooting for the underdog, and being the gun nut that I am, I just love hot loads.

I’m not too sure about PolyCase. Their bullets have been shown in several tests to penetrate like an FMJ and wound like a JHP and those are made of polymer (blended with copper). I personally don’t care too much for things made of polymer, whether it’s handguns or bullets, but that’s just me. Then again Glock wouldn’t be the successful company they are now if all handgunners think the same way I do.

If you want to try them out, no one’s stopping you. Feel free to share your experience with us by leaving a comment below.

The real star of the show is Hornady‘s XTP +P JHP. It ticks all the boxes and is the cheapest of the bunch at just 59¢ a pop. Everyone in the U.S. likes Hornady, I have yet to hear anyone complaining about their products. And these XTP bullets are literally everywhere, availability will never be an issue.

I would not dismiss all the other products here though. Underwood’s Xtreme Defender +P+ does overpenetrate but I wouldn’t hesitate to carry these super hot loads in an all-steel 9mm EDC piece, simply because we never know when we might need to shoot a bad guy hiding behind some sort of solid barrier. As some Jewish writer I know once said, “Better to have, and not need, than to need, and not have.”

Federal HSTs, Speer Gold Dots and Corbon PowRballs are some of the more established premium brands. I wouldn’t feel undergunned carrying any of these loads if they’re the only ones available thru my favorite gun dealer. My only real issue with these is being premium brands, they can be a bit too pricey.

Another obscure 9mm hot load option

If you happen to have a Glock 19, you might want to know about a conversion option for it called .960 Rowland (I swear I’m not a fan of Johnny Rowland — okay maybe I am, just a little).

It’s relatively new, I believe it only came out two years ago. But it’s supposed to mimic true .357 magnum revolver performance in Glock 19 handguns with just a barrel and recoil spring swap. Johnny’s Impact load boasts of a 115-grain 9mm projectile with velocities of up to 1,600 fps from a 4.25-inch barrel.

Best 9MM Ammo Conclusion

The 9mm as a handgun caliber is a great option for self defense, and there are literally a ton of good 9mm ammo out there. If you’re interested in a particular brand/design and they were not covered in this article, do your homework. Research on that load’s terminal ballistic performance and find out if they’re available in your area, as availability affects pricing.

Practice, practice

As with all else in life, choosing good 9mm ammo for self defense is never going to be easy as there are a lot of things to consider. But whatever you do, whether or not you end up ordering any of the ammo brands in this article, make sure you save some for practice shooting if only to familiarize yourself with how your handgun handles the loads —  specifically, how accurate the bullets are and how they recoil.

And never make the assumption that you can win every gunfight just because you have your mag loaded with some of the best ammo on the market. Always remember that in gunfights, shot placement is king.
