Albuquerque, NM --(  Please check out the below video from Paul Gomez about his thoughts on the 9mm versus the .45.

Aah, the never ending debate about the effectiveness of handgun ammunition in different calibers.

Some people are probably tired of this debate and have moved on.  They’ve already picked the cartridge that that they shoot best in their respective gun(s).  However, I do not tire of this discussion.

Not because I think I’ve already picked the biggest and baddest round for myself.  I just really enjoy the enthusiasm that this subject can produce from shooters. Plus, the information exchange during these talks is immensely valuable and sometimes entertaining.

In this video I like the fact Mr. Gomez points out that the only thing handguns do better than long guns is that they are easy to carry and conceal. But in most cases “handguns suck.”

This video got more interesting for me at 02:40 mark. He points out that with “modern defensive/duty ammunition,” all are designed to perform to the same standards.  The organizations that he mentions that designed the standards and test protocols are the FBI and IWBA.  With the FBI protocols, the ammunition is tested on 10 percent ballistic gelatin.  They have a required minimum acceptable penetration of twelve inches and a desired eighteen inches of penetration in the gelatin.

What really impressed me about this video were the the inserted pictures of various calibers of bullets ranging from 9mm all the way to .45  penetrating at almost the same depth into the ballistic gelatin just as he mentioned.  However, he definitely starts to clarify his argument later in the video that bigger bullets are indeed better because they will expand more and create a larger wound channel.

I must admit to having been very ignorant to these testing protocols, which is why I found this video so informative.  It also got me thinking about past discussions I’ve had on this subject where pretty much everyone disagrees on what caliber is ideal to carry for defensive purposes.

However, almost everyone seems to agree that ideally a person should carry the largest caliber handgun that they can shoot the most effectively.

What’s your take with regard to the best handgun caliber a person should legally carry for self defense in a pistol that can be carried and concealed well?

Also, what’s better in your opinion, carrying a pistol with a higher capacity magazine of smaller caliber bullets? Or, would it be better to carry a pistol with larger caliber bullets with a lower capacity magazine?

    1. Well spoken my brother. A pistol is just a rifle waiting to grow up.

      Stop the video at about 8:18, and take a good look at the width of the wound effects. This is tissue that is hit by the shock wave as the bullet is moving through the bullet hole.
      The bullets with the highest muzzle energies (a combination of velocity and mass) cause the worst damage when they strike the tissue of the target. Unfortunately higher muzzle energy also means more severe recoil. (A .45 kicks a lot harder than a 9mm.)
      The moral of the story is: You should carry the largest caliber that YOU can effectively handle to put multiple rounds on target. I would never ask a 90 lb grandmother to carry a .45, but I think most full size men can and should.
      On the other hand, if your aim is atrocious, then you will need more rounds in order to get enough on target to hurt your adversary. You should carry a gun with a large capacity magazine, until you can find the time to get the necessary training to improve your aiming skills.

      Remember that you are responsible for every round that you fire. Even the ones that miss your adversary … and strike an innocent victim in your neighbor’s house or apartment or your childrens’ bedroom.
      And you might not survive the gunfight long enough to wait for your 5th shot to finally be the one that hits your target.

      Make every shot count by 1)putting it on target, and 2)ensuring that your bullet type causes the most damage.

    4. I agree about carrying the biggest gun you can accurately shoot, I carry a smith 500. I figure even if I miss I can track em by the poop trail.

      I personally carry a full size Colt .45 with a Bersa .380 as a backup. As far a recoil goes between the two, they are about identical. The lighter the firearm, the heavier the recoil. I can get on target and stay on it with either. But a friend has a light weight small frame .45 thats almost impossible to control.

      My wife’s carry weapon is the Bersa .380 with a Taurus .357 magnum as a backup. The Taurus is a small snub nose 5 shot light weight revolver that wants to tear your hand off when fired. She is very accurate with either, but target re-acquirement is much slower with the .357. And after 5 shots with the .357 she is done with her hand (and mine) wringing from it. Even with .38 specials in it, its still a jack hammer. But she prefers it as a backup as not having to worry about any safety release in a panic must have situation.

      All are loaded with Hornady critical defense rounds for maximum expansion. The .45 is a slower and heavier projectile, larger wound with less worry of over penetration, the same for the others but smaller wound. The .357, I still wonder about it over penetrating.

      I am a larger guy and the full sized Colt .45 (a Combat Elite Series 80 MK4) conceales well with me and fits my hand perfectly, the Bersa grip with the rubber OEM grips fits nicely as well. Her Bersa has the OEM plastic grips and fits her small hands well but the .357 with its small grips fits her hand perfectly.

      Each weapon and caliber allows us to control them easily, each to our own fit. The only thing that has been customized on any of the is the Colt, it has the Houge wrap around grips with the finger reliefs to fit my hand better, allowing better control.

      We never found a 9mm that we would be happy with, or a .40 for that matter, even tho a 9mm is the most economical to practice with.

      In the end, personal protection is going to be up close and personal, so no matter the caliber, its operation and control (accuracy) thats going to count the most as well as a safe daily carry and concealment. We carry condition one.

      Just as a note, the Bersa .380 is marketed and boxed as a “less than lethal” firearm. But it has been used numerous times to the demise of perpetrators.

      You can see the percentages of one shot stops, listed by caliber and ammunition type here:

      I’d rather actual usage data than gel tests any day.

      PS. I am NOT affiliated with the above site, I just like the data.

      Screw both of em… I carry a 10mm!!!

      my dad a wwII and korean war vet advised that when it comes down to the gritty part of defending yourself to go as big as possible. he said the .45 was the best thing going. i have used both and have to say the .45 is my preference. it is big,strong and will knock down your opponent w/one hit.

      Let’s put this in perspective:

      If you are in a “shoot your way out” situation and it’s a given that you are gonna take at least one round, what had you rather get hit with? A 9mm or .45?

      That’s perspective.

      If you need 17 rounds in your magazine to survive a gunfight, you are hanging out in the wrong locations. The FBI stats I’ve found show that after 3 shots, your odds of hitting your target (if you haven’t already) drop like a stone.

      It’s far more important to hit your target with your first couple shots than it is to have an additional 10 in the magazine.

    11. 5.7 is really nice

      ill take a 9mm

    13. gun shop owner on July 3, 2012 at 7:25 PM said:

      a 9mm has less recoil allowing me to shoot rounds quickly at vital organs

    14. killer on July 3, 2012 at 7:26 PM said:

      2 9mm =1 45

    15. Keep my model 29 with 44 spec. hp’s

    16. or get .357 magnum and bypass the whole debate =)

    17. The round is less important than good placement of the round. Bad shooting is needing 15 rounds to hit a close target.

    18. Love both 9 and 45 but if I had to go i. Combat 9mm all the way more is more and hitting is everything!

      I wear a long mustard colored trench coat, and im always packin my old lever action 10 gauge loaded with 3 n a quarter inch slugs, for backup i got a 460 magnum and a 9mm with a modified 139 round clip, i usually just take it to sunday prayer meetings tho.

      People see a 45 round, and think damn that must be powerful as hell, it is big, but also slow, wont penetrate. Its still good, but it and the 9mm are prettt much equal, they will both kill a fella, now if ya want that bigtime power, go 357 mag, 10mm, 41 & 44 mag on up to 460 & 500mag. The 9mm, & 45 are bout equal slight edge to 45, then the 40 is right there with em, but 40 sucks, and no one fives a rats ass about it, bout like 357 sig, both of them suck and no one carries ammo for 357 sig, because its pretty much dead. At the end of the day… 9mm cant be beat. 100 years n still goin strong out sellin em all. Peace.

      A 45 is a big slow shitty round, the guns hold like 7. Hell just get a revolver, a semi auto that holds 7-8 is pointless. A glock 19 and a 10mm and your set. Maybe a shotgun too. Nuff said.

      Glock 19 Pistol

      if you are sharp shooter and one bullet is enough for you then choose .45 ACP but if you need more practice then choose 9x19mm (9mm), because 9mm is cheaper than .45 ACP, and in 9mm you can fully load the magazine into 15 rounds or more…
