9mm +P ballistics = .40 ballistics?

That's because you're trying to sell the world on .40 S&W


It would seem that I made a statement of fact about my shooting the 9mm, the .40 ant the .45 and noticed no real difference in recoil and you make me out to be some fan boy.

The fact is the difference in the three calibers recoil is barely felt by me.

maybe you are just very biased against a caliber that works for many people because it is "new".

It would seem physics are standing in the way of the validity of your perception.

It would seem that perception is only perception and physics has got nothing to do with it.

A 200 Lb. man is going to take the same amount of energy from a hit as a 100 Lb man will.

There is a real possibility that the bigger man is going to think it hurt more than the smaller man would.

Perception is not fact. It is an input into the brain after and event and decoded by the individual. We all have a different perception of identical things.

Save your perceptions for those who feel the same.
 
For some reason, this "debate" always seems to get started by people shooting the .40

I shoot'em all duke!

I pack the .40 cause I got one great deal on a night sighted 27. Already had a night sighted 26. Just started using the 26 for IDPA and carried the27 cause it has just a bit more wack. Just a bit more mind you, but it still has a bit.

If I had bought just the 9mm 26, I'd carry it and be happy (my prefered 9mm load is the winchester +p+ 127.) I just happen to have the .40 to!
 
Smith

I used to have 'em all, but I did give up on the .40 (I'd rather have the longer case instead;)) Nothing wrong with the .40 at all, just if you shoot it, don't have to knock a smaller round as to being "inferior" of some sort.

Usually I carry a .45 for cc and be done with it.:D

That said, had a guy come over to my house some time ago to do some shooting and get familiar with his gun. We go out back, he has a Smith in a
.40

I asked him why a .40 since he was new into shooting, and he told me that eveyone else told him that a 9 was underpowered and "wasn't any good" for stopping people:confused:

Here you have a new guy into shooting and my personal opinion is people are feeding him crap.

Funny thing, the guy was having issues hitting the target even at 7 yards with the .40, however, let him try one of my High Powers, and he was on the plate almost everytime loving shooting that gun (he still wants to buy it off me).

A caliber is only as effective as to how accurate you are with it.

The original question to this thread was answered, yet it still seems to come down to a 9 vs .40 debate.
 
fact

Perception is reality; THAT's a fact.
But one's "reality" is not necessarily "fact".

And recoil, while measurable, is still "perceived" by the shooter, regardless of physics.



I cannot get the image of David's rock out of my head.......and I wonder if it was a 9mm rock, or a 10mm rock, or an 11.4mm rock...
 
.40 S&W exists for "historical" reasons. The market liked it because there were a lot of 9mm designs that people liked and it was relatively easy to convert them to .40 S&W. Converting 9mm designs to 10mm or 45 Auto was harder and it didn't happen. That's what "killed" 10mm. So people got a bigger 40 caliber bullet in a design they liked and .40 S&W took off. Nothing wrong with that.


But then 45 Auto revived. Not that long ago, 45 was virtually synonymous with M1911A1. Now, though, you can get all kinds of 45s. If you can't find a 45 design you like, you're not looking.


So, why .40 S&W?
 
Duke,

You were cheating using a P-35. I made class 'A', IPSC, using a P-35 (granted back then most of the .45s, except custom ones, jammed at least once a match while my Browning never ever jammed!)

If I had to give up all my Glocks except one for competiton and one for carry, I'd just end up with a pair of Glock 26 9mms. One to shoot and not clean (the IDPA gun) and one for carry. +P+ Winchester 127s would be the load.
 
When we look at top-end loads with light bullets in both we see the following

Double Tap 9mm +P-115grn@1415fps=511ft.lbs.
Double Tap .40S&W-135grn@1402fps=605ft.lbs.

So, the .40 does have a fairly significant energy advantage. There is also a diameter advantage but I don't really buy that a .045" difference is going to be particularly significant. The biggest advantage to the .40 S&W is that it's available in heavier weights which enhances penetration in both soft tissue and auto glass. Whether or not the penetration and energy advantages outweigh the capacity and recoil advantages is debatable. FWIW, I'm not really a fan of the .40. Personally, if I need more than a 9mm I'll go on up to a 10mm or .45 and be done with it.
 
Perception is reality; THAT's a fact.
But one's "reality" is not necessarily "fact".

I perceive that you are a figment of internet noise...since you have no proof that you exist then you are not a fact, except unto yourself.

Reality is reality...perception is perception (see below)...a spade is a spade...as I have told my children a gazillion times before...call it what it is and drop the BS.

You just refuted your own logic...

Note... On acid one can believe one can fly, but that isn't true.

The perception is not reality....need I continue....?

Back to the thread that was dropped.
 
Reality is reality

To coin a great comedian - "Reality, what a concept."

And of course, there's the theory that unless you can actually see it, it doesn't exist. The store down the street isn't even there unless you observe it. Then there's the thought that the whole universe is simply a molecule on some giant being's fingernail. And there's the further thought that we have a tiny universe on OUR fingernail. But I digress.

I believe both the 9mm and .40 S&W have their place in the SD world - and most of that is what the individual prefers to shoot and carry. Military and LEO use is completely different than what we're looking for, and aren't fair comparisons.
 
Here's my take on the matter,

I just don't have much confidence in the 9mm as caliber that can quickly stop an attacker.
So I prefer the .45ACP caliber.

But I also prefer a high-capacity pistol.
The only problem with this combination is that all the high-capacity .45ACP pistols (like the Glock 21) are too fat for my grip.

Eventually this lead me to the .40S&W.
And eventually I bought a CZ75B Single-Action .40S&W, which I like alot but it still only gave me 10 in the magazine.
So I later bought a Glock 22 which gives me 15 in the magazine, and I'm very pleased with its performance so far.
I really can't see myself ever going back to a 9mm again.

The 9mm might be equal to the .40 in ballistics and gel, but it just doesn't give me the confidence I need, and IMO, one needs to be confident in one's handgun.
 
Patent #123456789

I am working on a new bullet design. I call it the 45-9-40. First I have a .45 round, then inside I have a .40 round, then inside the .40 I have a 9mm round.

The .45 nose is frangible and it crushes on hitting the target...no penetration, just surface trauma. Then the .40 continues on to make an initial cavity. The the 9mm has an additional charge that is ignited by friction from the .40. The 9mm then continues on for very deep penetration.:cool:

Regardless of energy, one is unable to make a .355" diameter bullet .400".

No but the .357 diameter 38spl +P+ I shot a guy with opened to .612 check my photobucket under Police Dept'

and...

What was the expanded diameter of the .400" bullet you shot the guy with?

(I don't fret caliber of gun; I fret skill level and shot placement and avoidance tactics and similar nonsense.)

I repeat; if I load my 9x19 and 40 S&W ammo using the same-weight bullet to the exact same velocity, how does logic and reasoning then apply?

I'm most certainly NOT arguing nor advocating either cartridge as "better", as that answer is obviously the 41 AE.



How do we feel about 'caliber of shooter'? 'Cause if caliber of gun were obvious we'd have enough evidence by now....
