    Where is the real world evidence that modern 9mm is as effective as a .40 bullet? I keep hearing people say modern 9mm jhp is equal to .40. How could that be? If that was the case why even go with the .40 like most Leo's do?

    .40 does better on windshields regarding deflection for one.

    Oh goody, another anti-caliber thread. Ok I'll bite.

    Generally .40 is marginally better than 9mm. .45 is marginally better than .40. And so on. Hell .500S&W beats them all. Are you going to carry that? There are other considerations besides raw power. Weight, cost, capacity, recoil control, shot-to-shot speed, etc infinity.

    Here's some stats for Ranger-T JHPs. The case could even be made that the 9mm is MORE effective.

    Bare Gel:

    9mm: 13.9" penetration .65" expansion
    .40: 12.7" penetration .6" expansion
    .45: 11.6" penetration .75" expansion

    4-layer Denim:

    9mm: 14.5" penetration .66" expansion
    .40: 14.3" penetration .7" expansion
    .45: 12.7" penetration .72" expansion

    I shoot .40 occasionally. I absolutely LOATHE the kick. You asked why even go with the .40 if the 9mm is just as effective? The real question is why go with the .40 when you can have a .45?

    a buddy of mine was carrying a .40 on duty when he was shot and killed by a guy with a 9mm. 1 shot. POS 115gr. didnt even come close to exiting. still dead.

    my former captain got in a shootout with a kidnapper (who was using a 7.62x51 semi auto rifle) with his issued .357 magnum S&W model 19 around 1980. upon autopsy of the offender it was found that the .357 SWC my captain fired went through the perpetrators heart, flatted out and did enough damage to stop bloodflow to the rest of his body instantly. guess what the guy did after he was shot through the heart.


    he turned around and ran 800y before collapsing of lack of oxygen in his blood stream. yeah, 800, rifle in hand.

    what does that tell you? it tells me that unless you get a CNS hit all bets are off and any caliber debate between the difference of .045" is limited to academia. because in the field their will be so many other variables that **** wont even make a difference.

    does .40 have more potential than 9 in the best of scenarios using the same bullet, probably. just like .45 would have an edge over .40 shot for shot in the same scenario in soft targets. however, no two gunfights are ever an apples to apples comparison and the only certainty is uncertainty.

    now why did you have to go and kill another thread with facts and logic?

    mo rounds

    mo reliable expansion from a shorter barrel

    mo better to carry a smaller, lighter gun

    and the pop of the .40 is mo better too!


    :cool:

    I love these threads! I'll pour some gas on the fire;

    I heard that a .45ACP round fired from a GLOCK has 9 times the stopping power of that same .45ACP round fired from a 1911.

    :tongueout::rofl:

    Geez, now I'm really confused. Why don't we get a bunch of goats & shoot them to see which works best? Oh wait...

    Think of the 40 as a 45 in a 9mm platform. Same terminal effectiveness as the 45,etc. The 40 and 45 are slightly better than the 9mm, but the performance gap isnt quite as great as most think.

    According to this logic...

    .355<.451=.400

    ...or is it

    147<180=230

    ???

    I am not following...

    It is against the laws of physics for the 9mm to equal the .40. I am a 9mm fan and think it is a great manstopper with the proper round, but with the same bullet the .40 will always outperform it.

    I guess that depends on your definition of performance. To me stopped is stopped and dead is dead. If in one shooting one 9mm does the job and in another one .40 doesnt, then some would argue that the .40 didnt exceed the performance of the 9. its semantics.

    capacity and size..

    Regardless... PLACEMENT iS KEY! It doesn't matter if it's a 9mm, a 40, or a 45(only the 10mm "hits even when it misses" :))..

    i heard the .45 GAP beats the .45 ACP and the 9mm, but has a 1% less stopping-power percentage than the .40....

    now im really confused...LOL

    which is better? Honda or Toyota? Ford or Chevy? I've come to believe that the .40SW is that much better than the 9mm so that's why I'm gonna sell my G27 and keep my XD9 and G19 :D. I'm confident i can kill the bad guy just as dead with a 9mm and it cost less to shoot.

    screw it, I'm just gonna stick to my 22LR :D

    I read about the SAS and their choice of pistols. They use Sig 228s and 226s in 9 mil and are taught that a 9 mil is a "multiple hit" weapon. They do very well with double taps. I'm guessing a quick tight group of three rounds in the chest is a good way to do some cardio vascular damage. Three rounds can be fire in less than a second. Practice practice practice.
