This debate has raged for decades, but it’s important to settle for yourself when choosing a defensive caliber., Read what some of the best have to say HERE

And here we go again … you already know that you can’t go wrong with either of these classic calibers. But it’s a debate that continues to create controversy among shooting enthusiasts everywhere. Each round has its pros and cons when compared, yet each remains a staple among firearm fans.
Read on for not just some of the same old argument (there’s some of that), but considerations from our Team Springfield™ SMEs on which caliber may be the best for you.
The greatest attribute of the 9mm cartridge is that it has the easiest-to-manage recoil. Pair this with the weight of a full- or mid-sized pistol, and handling will prove to be comfortable and pleasant. And this combination is also a perfect gun for brand-new shooters to start with.
PRICE & AVAILABILITY
If you don’t want to go broke buying range ammo, then 9mm has your back. Due to its prominence among our military and law enforcement communities, and popularity with civilians, the 9×19 is the most commonly-encountered pistol round world-wide.
This and the relatively small amount of material used in the manufacturing process also makes 9mm the most economical center-fire pistol round currently available.
When it comes to personal defense, the 9mm is more than ready to do the trick, especially with hotter +P (increased velocity) hollow-point loads. Its lighter recoil makes follow-up shots quicker, and the smaller size gives 9mm pistols additional round capacity.
Team Springfield™ SME Ivan Gelo, is a huge fan of the .45, but knows that much of the comparison bullet “data” stems from bullet performance technology that is over 25 years old. Like most tools, equipment and devices, bullet technology has grown by leaps and bounds over that same period, especially in the area of the 9mm pistol round. Ivan says that, “Old 9mm technology was related to the .45 and the concept of the heavier bullet; hence the widespread use of the 147 grain 9mm bullets. With advances in technology though, the more common 9mm 124/125 grain +P loads have substantial stopping power. So with greater mag capacity and the lighter ‘carry’ weight, the 9mm benefits are easy to argue.”
If you have any physical limitations, i.e. carpel tunnel, tendinitis, loss of hand-strength, etc., Team Springfield™ shooter Kippi Leatham recommends the 9mm over .45 without question: “I shot larger calibers through many of my competitive years. My first competition gun was a 1911 .45 — and I loved it! Eventually though, over several decades, I developed tendinitis in both elbows. With continued proper strength training and a decision to shoot exclusively 9mm pistols, my elbow injuries are no longer an issue.”
So if you have physical limitations or pain, don’t continue to damage your body or create discomfort in exchange for greater stopping power. In Kippi’s opinion, a well-trained, competent and confident 9mm pistol owner is easily able to defend him or herself should the need arise.
The terms “stopping power” or “knockdown power” are concepts popular with the self-defense crowd. The .45 regularly is considered to have more stopping power than a 9. It’s a big reason why it was adopted alongside the 1911 for U.S. military service back in the day. While its velocity is slower than 9mm, what you lack in speed, you more than make up for in a larger and heavier projectile.
To its fan base, the .45 is the best round for law enforcement and personal and while the .45 does obviously have more recoil than 9mm, that is the cost of increased power.
Curiously, decades later the US Military also adopted the 9mm and widely replaced the .45 with it, but for more reasons than power alone. Many Spec Ops groups did not change, and retained the .45 for its greater power.
Team Springfield™ Captain Rob Leatham says, “My position on this subject is well documented: I like the .45. While currently, I do shoot more 9mm in competition than anything else, it’s because of the rules and subsequent advantages the lower-powered, lighter-kicking 9 has. For defensive use, especially in a mid- or full-sized, easily controlled pistol, I would choose the .45 every time.”
FROM THE PREPPER’S MINDSET
Steve Horsman — Team Springfield™ Expert Prepper — has multiple guns in an assortment of calibers. But he does have a preference when carrying for self defense. He likens the .45ACP v 9mm debate to hunting. Steve states that choosing a 9mm for self defense, with the higher-capacity, lighter kick, and lighter-weight, is like him choosing to hunt elk with an AR 15 with a 30 round magazine. “No one in their right mind would ever use a .223 for elk hunting; they would more likely choose a .308 [minimum]-caliber rifle. Given the choice, I will pick the bigger bullet with more power every single time.” Magazine capacity alone cannot and will not substitute for power and accuracy.
Apple pie, baseball, bald eagles, and .45ACP! This cartridge has a proven track record in America that dates back over a century. It was trusted by the United States through two world wars, and, while its use among the military and LE agencies has lessened more recently, it still serves a large role in many specialized units, as well as remaining a favorite of many civilians.
Supply of this cartridge should also be high. The .45 auto has been around for double-digit decades and while pricier than 9mm, the large quantities in which it’s produced makes it easy to find.
PICK ONE AND PRACTICE
To summarize, both the 9mm and the .45ACP are great self-defense rounds. Though a 9mm pistol will hold more rounds, the .45 ACP definitely packs more punch.
So as with most things firearms related — pick your preference: heavier and more powerful cartridges with more recoil OR a caliber that allows for greater capacity, less recoil and a lower cost to shoot.
And as you read above, even our Team Springfield™ SMEs don’t agree on caliber… but they do agree on this:
Whichever caliber you choose, put some rounds down-range, shoot a lot of them actually, and make sure you train on a regular basis. Become proficient with your caliber of choice, because that is the best way to maximize the effect of any firearm that you carry for self defense.
