OP, you really need to take a class or read a book on terminal ballistics. Then draw your own conclusions. I will summarize what I learned:

1) All handguns suck at stopping determined aggressors.
2) All handguns SUCK at stopping determined aggressors.
3) If you're going to get around handguns sucking, you MUST hit the central nervous system (CNS) or brain. Alternatively you can hope for the criminal to bleed out, which can take many minutes or hours. If you hit a major artery like the aorta, this can be reduced to seconds.
4) Everything you want to hit is basically in the center chest area, and if you miss the CNS, there's lots of good blood vessels there.
5) Caliber doesn't matter. You want to penetrate deeply enough to reach organs, which is why everyone doesn't use a .17. .380 from directly facing someone is exactly as effective as .45ACP at immediately stopping someone. Either you hit what you need to hit, or you don't.

To distill it down even further:

1) Handguns suck.
2) Shot placement is literally all that matters assuming your bullet penetrates deeply enough to hit organs.

Why do police carry .40? Marketing, and a lack of knowledge. You'd be amazed how little research into terminal ballistics is done by police and militaries making decisions.

Either will do.

Whichever you shoot best.


9mm is plenty enough. .40 is as well.

I encourage everyone to watch the FBI shoot out that occurs in floridia awhile ago. It may shine some light on the effectiveness of handguns against attackers if they really won't stop until dead. The firearms used were .357, 9mm, 13 gauge and a mini 14.

The strategy is pretty to to simple practice. I have a two step practice method.
At 15 yards:

1. First shot to center of mass.
2. Head shot.

Practice slowly at first and when you feel bored or you got it wired increase speed. It's not rocket since. Use whatever caliber you like. I practice with 9mm, .40 and .45 after all variety is the spice of life.

This guy was shot 2 times with I believe 9mm ball ammo. That is what is used as a typical police round in these countries. It eventually kills him but look at the time it took. Had he had a gun, the gun fight would have continued.

It is important to know people just don't fall over from a gun shot.

ScotchMan nailed it.

Militant,
The Miami shoot out story is a good point of reference in that it demonstrates the relative shortcomings of handguns. For that purpose, I like your suggestion. The downside is that the Miami story has given birth to a lot of bad assumptions. Ammunition then simply doesn't compare to what we have now, in terms of penetration or expansion. People reviewing the Miami shoot out should keep it in mind that that event revolutionized the ammunition game, and appreciate how far .38spl, 9mm, etc have come as a direct result of that fiasco.

I conceal carry a .357 mag 6 inch barrel in the winter with a heavy coat on and in the summer I carry a .357 snub. I had a 9 then a .40. I can shoot revolvers much more accurate so that's what I carry. I personlly would hope to have a 12 gauge with 00 buck if my life was on the line.

Might I also add that in that firefight with the FBI, agents were hit with the .223 in the neck and the perp was hot with 12 gauge in the face. The .223 did not kill the agent but did paralyze him and the 12 gauge some how did not stop the perp.

Thank you ScotchMan. I pretty much tried to sum it up to the exact same thing for him.

1. Only hits count.
2. The hit must be sufficient to change the BG's channel.

9mm or .40

I carry 9mm in my pocket. That's what fits. Besides, my ammo gives me 1400 fps for 115 gr Gold Dot bullet. That's about what .357 Sig does, nearly a .357 mag. What need do I have with .40 or .45? I ran across this stuff in Grants Pass, OR about 20 years ago, and it doesn't exist anymore. Glad I loaded up when I did. Even today's best loads don't match it. I used to carry it in my old .32 Keltec P32 until I experienced "rimlock". That ended the .32. Now I get to carry a 9mm Keltec PF9 with my fab ammo.

You have a 9mm round achieving 1400 fps? Chrono pics please.

The same would probably apply to most handgun rounds.

Scotchman said caliber doesn't matter, it is penetration that counts. Many posters agreed with him.

Well, isn't this where .40 S&W has an advantage over the 9mm?

The .40 hits harder with heavier bullet and penetrates deeper.

Not true. No. And no. And no.

They're about a equal. Different loads do different things. One may surpass the other which may surpass the other. There isn't a "one penetrates more than the other" between .40S&W and 9mm. You're wrong.

The 40 can go up to 180 gr bullet whereas the 9 peters out at 147. Assuming the same bullet design, FMJ vs JHP, wouldn't the bigger, heavier bullet hit harder? If not, why not?

Apparently the laws of physics don't apply to the 40 vs 9 debate.. Oh well, train with what you feel comfortable with.

9mm or .40

Here is photo of ammo boxes for my 9mm and .40. This stuff was made for cops in south Oregon. The .32 I had was 60 gr Gold Dot at 1250 fps.

It is interesting that, in the Miami shoot out, it was the lowly .38 spcl +P that ended the fight. Agent Mireles shot 6 rounds out of his S&W 686, the first round missed, but the second round shattered driver side windshield, 2 rounds hit Matrix in the face, the bullets travel downward and severed his spinal cord and the 6th round hit Platt right on the chest close up, killing him instantly and ended the shoot out.

I don't know what weight bullet in his .38 spcl +P but considering they are the FBI. It would not be unreasonable to assume the 158gr +P LSWCHP.

Barcat6, Have you checked out Underwood ammo yet - both 9mm and .40 cal?Youtube videos show that Underwood's figures are not exaggerated and in fact perhaps understate figures. http://www.underwoodammo.com/

So, basically caliber does matter, but just not once you pass into the 9mm range.

I did apologize previously for not doing a through enough search the first time. Being new to the whole gun community I had no idea that this was such a hotly debated issue.

Also, if they were so easy to find, maybe next time with your first post, you might want to trying being nice and include the easy to find links rather than being a smart alec.

Finally, if you don't want to be involved in another "caliber war", then don't. No one has forced you to post 4 times in this thread.

To CurlyQ.Howard: I notice the 115 gr 9mm are +P+ at 1400 fps. My ammo is not +P+, or +P. Mine is fit for ALL 9mm pistols at normal SAAMI pressures.

My first post was from a phone, so I wasn't go to do your job for you on a 4" screen. I thought my very clear comment early in the thread might prompt you to search for yourself, and I pretty much summed up the message that you were going to get from everyone anyway.

My second post elaborated further on what I said in my first post, since somehow the thread was still going.

My third post was a joke.

In my fourth post, I decided to finally post some links for you, even though I shouldn't have to.

But hey, you're right - forums are for discussion. I keep posting in this discussion. So I guess, as many times as this topic has been brought up before, we will still talk about it. No offense intended.

I'll be honest, I mostly ignored your first post because of the tone. I understand that you were on your phone, but something more helpful like:

"I see that you are knew here, this is a topic that has been debated for years. I suggest doing a search for '9mm vs 40'. That should give you more info than you want.

would have gotten your point across (in fewer words) without sounding like a jerk, and probably would have gotten me to do that search earlier

Please understand that I am very new to this forum (you can tell by my number of posts) and handguns in general. I honestly had no clue that this was such a hotly debated issue, I didn't do a very deep search (apparently I did a fairly pathetic job) before starting this thread. I'll admit that your 2nd and 4th posts were VERY helpful, thank you for that. Your 3rd was obviously a joke (al be it one that helped continued this thread that you wish didn't even exist). I'll probably look at the most recent of the ones you posted (about 2 years old), but I think I've decided to stick with the 9mm for now.

Also, I do now see that there are two very entrenched camps on this topic, and to be honest it may not be possible to sway either side either way.

Advantages of 9mm
1) Less Recoil
2) More shots (given the same weapon frame)
3) Cheaper practice ammo

Advantages of .40
1) More oomph

The question (and the one that will probably remain forever is "Is the extra oomph of the .40 enough to overcome the negative of fewer shots and more recoil?"
