.40 S&W vs .45 ACP

I'm offically opening the can of worms and ooopps........I just spilt 'em.

Ok, heres my question. Why does everyone like the .45 ACP so much when the .40 S&W is cheaper and ballistics seem to favor the .40 better. Now before anyone goes off on me, I know the average .45 weighs in at 230 gr. vs the lighter 180 gr .40. BUT, the .40 is faster and generally puts more numbers on the board when it comes to ft/lbs of energy, so what up with the .45 following? I'm not saying the .45 is a crap round or anything like that, I was just wondering why there aren't more .40 cal fans than there are?
Is it just because the .45 has been around longer?

It seems to be that the 9mm and the .45 are the most popular semi auto round offered. Whenever someone that doesn't even know anything about handguns decides to get one, they usually get a 9mm or a .45. Just like the way my boss bought a Glock on the name alone. He doesn't know anything about 'em, never been around one or handled one. He didn't do any research on 'em or anything. He didn't even know that they make different models in a particular caliber. He just ordered one on name alone. Oh yeah, and guess what caliber he ordered.......... .45 ACP. Go figure.

Personally, I wish you could find more .40 cal 1911's than are offered. Maybe Ruger will decide to make the SR1911 in .40. I can only hope.

I think people get too caught up in caliber wars. The fact is that most pistol calibers aren't very good at dropping a bad guy.

But, I do have a friend who is a die hard .45 ACP guy. I think it's because his dad was like that and now he is like that. That and he hasn't done any research at all into ballistics and thinks because it is bigger that it must be better.

I don't really think I'm caught up in a caliber war, but I know what you mean. It just seems to me that from a cost/stopping power standpoint, the .40 S&W is a more efficent choice.

I always hear the sledge hammer vs tack hammer argument (9mm/.40 vs .45) when this topic comes up but my .40 is really starting to grow on me and for me it's the best of both world so to speak.

I'm a fan of all pistol calibers because i love pistols and revolvers. Havin said that, i'm a 40 calber affectonado too. In the spirit of "there aint nothin new under the sun" i would recommend reading this article by one of my favorite gun guys, John Taffin (...here is the link: The 40 S&W ....) John says he thinks that the 40 is a "rebirth" of the old 38-40. I think he is right. When ya consider the availibility of ammo and reloading components for the 40, it's indeed a great caliber to shoot with and it's plenty powerful. I like it.

the .40 was a solution to a problem that did not exist.

in my opinion, the .40's recoil is too snappy. i think it's easier to shoot a .45.
i am a 9mm fan, so i don't care either way.... but i don't think the slight advantage in "power" is worth the price you pay for the snappy recoil. and if i did want to trade power for recoil i would just get a .45.

You know any of them will do the job really. I have been watching 48 hours lately and a simple .22 was at fault for a few Homicides.


For up close and personal a .45 will do everything and make a big hole. The .40 from what I can see shoots flatter at a distance which would help law enforcement on longer shots or maybe a barrier.

10mm just kills them all

I only have 9mm and .40 cal guns simply to keep the cost of ammo down. For plinking I use my 22 Mark III. To be honest I would not want to get shot with any cal gun and would not know the difference between 9 40 or 45. If I could I would be heading in the other direction if I were a bad guy.

I can see your point. Thanks for the comment.

That's true. Any of 'em will do the job. Shot placement is the name of the game.

10mm will never be an option for me. That extra little umph you get from it ain't worth the cost and lack of availibility of ammo.

With all due respect,I disagree.It actually was the perfect solution for shooters who felt a 10mm was too much gun.

I think the exact same thing. Personally, I can't see getting a .45 when you've got the option of a .40. You get basically the same power at a cheaper price.

I have both .40 and .45 with complete confidence in both. I practice with both, reloaded both, carry either but tend to carry my Glock 23 more often than the Sr1911 or combat commander because of the weight.

Have to admit the Ruger is getting more shooting lately.

An interesting thread from Iowegan in the library on momentum. I am personally a large bullet fan even though I carry a 38 Spl +P load. That 158 gr bullet gives me a momentum figure of 23.2 lb-ft/sec and a M/E of 372 ft/lbs out of a 2 1/4" bbl. There are different ways of judging performance and a bigger bullet obviously has a larger frontal impact and the big bullet digs deeper. Having said that either the 40 or the 45 will work fine and the key is what you can shoot the best.
