Default 9mm vs 40s&w vs 45acp is silly

power structure brand for brand (blazer brass el cheapo)

.40s&w 155jhp 475ft/lbs at 1175tf/sec

45acp 230jhp 365ft/lbs at 845ft/sec

9mm 124jhp 351ft/lbs at 1126ft/sec

this was all Blazer brass ammo all fmj all cheap crap so yeah cost for cost the .40 rains supreme and is just a hair under the

.357mag 158g 494ft/lbs at 1150ft/sec

the numbers dont lie so any thing else is just a matter of preference

What are the barrel lengths of all four guns?

"assuming" that blazer used the standard 5" test barrel for 9, 40, 45 and the standard 6" for the .357mag

then i guess that would be it being as that info was not stated,,

i came upon this when a friend and i were arguing that the .40 vs .45 thing,, i told him that my .40 shoots flatter and hits harder out to 30 yards (i was correct) but he wouldnt hear it

so i looked here

Ammo matters. I would never use Blazer brass to judge anything. The only ammo I refuse to use in any gun!

Hornady critical defense...

9mm 115gr 1140/332 4" barrel
40sw 165gr 1175/506 4" barrel
45acp 185gr 1000/411 5" barrel

The fact is you can't compare a caliber based on the same ammo, you have to base off of the best ammo available. For example, the federal 357 mag is unbeatable by any factory round for any caliber.

Then there's those wonder rounds like halo points and safety slugs. There's simply too many variables to play the ballistics game.

Put your bullet where you can and choose the gun you're best at achieving aim with.

I think you're missing a key factor here... velocity and energy are not the only points of comparison. Notice how there's over 100gr difference between the 9mm and 45? That 100gr at 1000fps is nothing to dismiss, which equates to more than just energy at impact. Hole diameter, aim forgiveness, etc, etc, etc.

i understand all that but what i was originally arguing with my friend was that the .40 brand for brand type for type hits harder and has a flatter trajectory then the .45

The numbers by themselves are totally useless! To many people who are not well informed or educated in terminal ballistics get all hung up in the 'numbers'. The ONLY thing that 'stops the fight', short of a central nervous system hit, is oxygen deprivation to the brain! This is caused by blood lose from a large permanent wound cavity (long and wide the shape of a foot ball).
If you use the 'best' defense ammo available today for the a fore mentioned calibers there is less than 5% diffidence in this wound cavity, so for all intentness and purposes they are all equal. But as ask above, 'what is the barrel length?' The 45 acp loses it's MV VERY fast when you shorten the bbl length and it is a 'slow' round to start with so if you go below the 4.5 inch bbl in the 45 you will be VERY disappointed in it's performance as a self defense weapon.
Don't take my word for it, do your own research and you will find the same thing I did!

Very wise decision. I've had them all, 9mm and 45, I'll stick to my 40 S&W.

I have unloaded all my .40 handguns, I just dont care to shoot all day with the high pressure cartridge , its not comfortable to go to a class and shoot 200-300 rds , I will stick with my 9mm and .45 . If you enjoy shooting the .40 more power to you , if you wanna make a bigger step jump up the the 10mm
