Advantages of 40 vs. 45 ACP?

Sheeish

.40 S&W and .45 ACP are specific cartridges which have caliber as a characteristi.

for the O.P. the .40 S&W was designed for an overall cartridge length (O.A.L>) to fit the same length magazine well as pistols designed
originally for a 9mm LUger/9x19 cartridge.

Price - example Double Tap similar bullets
.45 ACP $38.95/50 rds
.40 S&W $35.95/50 Rds

1 small advantage of the .45 ACP is
shot shell ammo available for it. Anybody
know of a company making shot shells
for the .40 S&W?

Another advantage of the .45 ACP - in the
230 gr. defense loads it's subsonic < 1120 FPS
which is quieter than having the sonic booom
added in to the gunblast.

CCI makes shot shells for both the 9 & 40 S&W.
 
This is like the 41 mag 44 mag debate.
Good points -41 is more powerful than 357 and kicks less than a 44.
Bad points-41 kicks more than the 357 and isn't as powerful as the 44!
No need for the 40s&w or the 41 mag.

Huh? If you don't like 40S&W, just say so. Trying to discredit something you don't like by using a line of BS like you just used is like Obama taking credit for cutting the defecit. Congrats, you and Obama share the same sense of logic.

You say increasing the diameter from 9 to 10mm is "nothing to get excited about". Maybe you're right, it's roughly 1/2 a caliber (.355 vs .400). Doesn't sound like a lot - maybe it isn't. But just for the sake of argument - and objectivity - let's check the difference between the diameter of 40S&W and .45acp. Well slap me silly - it's also roughly 1/2 a caliber (.400 vs .451). So you dismiss 1/2 a caliber increase from 9 to 40, but champion the 1/2 a caliber increase from 40 to 45?

So you say a 40S&W is a "9x19 plus" and a "9x19 with a bigger ego"? Huh?? That's like saying the 45acp is nothing more than a 40S&W with a "bigger ego". Both statements are blatantly false.

And for the record, I own and shoot all three calibers. In reality, there are advantages and disadvantage for each. What is gained by making false statements to justify or rationalize one's choie of caliber?

The Obama thing was uncalled for. You may be technically correct, but back off a little. Just the facts, Mam' just the facts

Other point: .357 is the gold standard man stopper so there is no need for any other round.

Just because you're not a fan, doesn't make it obsolete. I have .40s and .45s, I like the increased capacity of my .40s

Well, it might not have been necessary, but I did think it was funny.

Me, like many others on this fine forum, know that 40 S&W is an inferior and unneeded caliber. That caliber is very popular, though, just like Obama as a president.
 
The stopping power of the 40 is equivalent if not better than the 45.

Obviously, the .40 has consistently high stopping power. The .45 is roughly equivalent. The .357magnum, mostly a revolver caliber, has exceptionally good stopping power with an inexpensive Federal 125 grain jacketed hollow point.

Secondary defense calibers, with lesser but still effective stopping power, are the 9mm and the .38 Special. In both calibers, the most effective load is the Cor-bon 115 grain JHP+P. Both of these calibers, especially the .38sp, are known to have limited ability to penetrate intervening obstacles like automobile windshields, or hard targets like the human skull.

Corbon 115grain Jacketed Hollowpoints +P(highpower) are the clear winner...but these hot loads are expensive and should only be used in high-quality guns that specifically say they are suitable for +P ammo.

Personally, I like 9mm, 45, 40, 357 and 38 special.

I just want the bullet to be in the .380 inch range or larger.
 
Flatter trajectory, wider range of bullet weights, ever-so-slightly better terminal ballistics (if you believe the FBI study), and since it was designed to fit into a modified 9mm platform its firearms are traditionally smaller and lighter with a higher capacity.

Not that the 45 doesn't have its own advantages-- operates at half the pressure of 9mm/40/etc., displacement (.45") and bullet weight (hard to argue with 230gr).

Pick the one that shoots most accurately in YOUR hands.

Well, I guess it's settled then. The sicence of sasu has spoken. Just like the science of man made global warming. Once the science has been settled, the debate is over.
 
Thank you for accepting the facts. Please remember to vote for me when I run for an office. You need smart people like me to manage your lives.
 
I had a .40 once. Discovered that I couldn't shoot it near as well as either the 9mm or the .45. Tried several factory loads and uncounted handloads, but the accuracy just wasn't there. Might have just been my gun, but I've never bothered to buy another to find out.
I'll stick with my .45s. I shoot it well and am completely satisfied with it.

I notice that some of you .40 lovers seem to be a might touchy about others putting it down. Kinda like Glock owners.

martialcomp,

Those 'one shot stop' percentages are based on statistically unsound methodology (like disregarding data that did not 'fit'). No weapon that can be hand or shoulder fired by an individual (except for rocket assisted and/or explosive warheads) will reliably stop an assault with a generic torso hit. Even the 12 ga. shotgun with full power loads will sometimes fail to produce the desired results.

Human beings are not computer models or bags of generic jelly. Like most other vertebrates, they have large areas that contain no mechanisms that are immediately required to sustain life or purposeful action. Hits in such places, even with the afore-mentioned shotgun, will depend far more on psychological factors than on actual physically causal effects for 'stopping'. Purposeful activity can be maintained for short periods of time even without a functioning circulatory system. You may have just inflicted a fatal wound, but failed to prevent the dying assailant from finishing his immediate business.

As I mentioned previously, there is no real difference between the permanent wound channels created by good bullets in any of our standard 'service' calibers. The only exception to this might be the .357 magnum using true 'full power' loads and even it fails far too often (in one case, a petite female was able to kill her ambush assailant after he nearly destroyed her heart with a .357). The full power .357 should not be included in a consideration of 'service' calibers because its blast and recoil make it difficult for the average person to shoot well under stress in a revolver of 'normal' size and weight.

The controllable 'service' cartridges all have 'power factors' of between 130 and 180 or so and produce muzzle energy levels in the 350 to 450 foot-pound range. This is far too little momentum or energy to reliably do the job. Consider the rifle cartridge recommendations for hunting deer. Deer are about the size of human beings and are usually no threat to the hunter, yet most people who have extensive experience will recommend nothing less than the .30-30 WCF (or its equivalent) for deer. Even the lowly .30-30 dwarfs any of our 'service' pistol cartridges in power.

We carry pistols because rifles or shotguns are inconvenient. We should focus our attention on becoming proficient with a pistol that we will actually carry - every day. We should choose that pistol for reliability, controllability and 'availability'. As long as we can put the bullet where it belongs (accuracy and penetration), caliber considerations are irrelevant. Is your chosen cartridge 'inadequate'? Yes, but so are all the rest...
 
The 40 S&W has a lot of detractors but in it's defense one must realize that you have alot of advantages - nearly the same expansion and penetration of the 45 acp (especially shooting through car doors and windshields) with nearly the capacity of the wondernine. So really it is an effective cartridge of comprimises that fills a need.

I'm not sure where all the statistics are coming from, but I'm going to throw in a couple pennies worth. I never trust the latest Gov. reports on balistics and stopping power. What I do trust is the several wars this country has been involved in. This brings to mind the Spanish American war in which the .38 cal. military issued side arms where absolutly worthless. Granted it was the .38 colt. Many soldiers stated they would have been better off throwing rocks at the enemy. Thus enter the .45 cal. Colt model 1911. Again involved in two world wars and many other campaigns in which EVERY report from actual soldiers killing the enemy had at least a 90% or better "one shot stop" and in many cases death. I enjoy reading and this is one topic that is found in many of our wars history books and records. Just what can a fresh collage grad. working in a lab for the FBI or some other Gov. building tell me or anybody else about stopping power or killing power that history hasn't already. My thinking is the old .45ACP or even the 45 LC is a tried and true man stopper. I know this is why I own several and enjoy shooting them. When and if I need to defend myself or my family, I know I will be very well armed. Truth is the bigger the hole the better. And it does not take a supersonic bullet to acomplish this. I do agree that shooting through cars and other various objects may be a different story. I appoligize for the very short history lesson, but we all can learn from our history. Our military went to the nato 9mm simply on account that there is more females in the militay (amongst other reasons) and recoil was an issue. It is a fact that the military now teaches "three shot stops" and not the older "one shot stop". In my opinon thats why the smaller cal. guns need the additional magazine capacity, need more shots to do the job. I will never give up my .45's as our countries history states loud and clear this round is one hell of a manstopper. Just my two cents.
