Carry Calibers: .40 S&W Vs. .45 ACP Vs. 9mm

Is this video a joke or serious? A 9mm is only capable of inflicting flesh wounds? And a 9mm round just bouncing off a tin can? 😂😂😂
That’s Chris Baker from Lucky Gunner in one off his “Manny Mansfield” character videos where he spoofs popular gun and ammo arguments, like 45 ACP is the only caliber a manly man would use. His “Manny” character videos are made for pure fun & laughs.

I really wish he'd do more of those. They are hilarious. I also really like the one he did on 'pocket pistols.'
 
It doesn’t matter.

Seriously—IT. DOESN’T. MATTER.


Pretty much all handguns have the same % of a stop after 2 or more hits.

So practice to make those hits, and stop worrying that your gun isn’t big enough.
 
Quote by Dr. Gary Roberts

Basically all the standard service calibers work when using good quality ammunition.

Keeping in mind that handguns generally offer poor incapacitation potential, bullets with effective terminal performance are available in all of the most commonly used duty pistol calibers—pick the one that you shoot most accurately, that is most reliable in the type of pistol you choose, and best suits you likely engagement scenarios.

Unless your department picks your caliber for you, pick the platform you shoot best, then decide on caliber from there. Basically all the standard service calibers work when using good quality ammunition; the platform picked tends to dictate the caliber
They are all around 350-400 ft-lbs of kinetic energy, some of the lighter/cheaper 9mm is in the low 300's for K.E.
.357 Magnum and 10mm gets up into the 450's and even higher, for K.E.

Seems to be saying shot placement is more important than caliber. And thus, pick the pistol you shoot the best.

.44 Magnum and .50AE does make a big jump in K.E. but also are limited in the pistols in that caliper, that also would be a challenge to use as a EDC or CCW.
 
Dang ... seems there is not a lot of love for the .40 S&W. I guess if you all don't like it I might as well sell it now. 🤪 Then I have to buy a 10 mm so you all can't talk about me ... that much anyway.

Glad I also have a couple 9 mm's for those tin cans and a "new .357" for the woods (my Christmas present, still in it's box, not even wrapped yet so I have to keep staring at it, ugh).

I'm not gonna fret too much about calibers here, I'm sure even my .380's will provide some good results when hitting the right spot.

KE doesn’t wound. In fact, it’s quite easy to have a caliber with higher KE that will wound less than one with lower KE.

Permanent channel is the only factor that matters with handguns.

Besides contributing to the permanent wound channel (mechanism of injury), KE also caused a shock wave into the body thus causing trauma to additional body parts. Example - a deep bruise

Kinetic energy in a moving object is never lost, but may be transferred to another object. When the energy is transferred to another object, it will be accelerated. If this energy transfer is to a human body and is above the level the body can tolerate, tissue damage will result.

My Christmas present has been hidden away and I don't know where, it's a Taurus G2C in (Gasp) 40 S&W.
 
A Ranger NCO I trust said that he hated the 9 and would've rather carried a shotgun. I carry S&W MP 40 shield and it's been trying to convince me that my grip isn't sufficient to handle it for 2-3 years. The 9mm price and capacity features do seem to be a bonus.
 
Bullet tech has improved greatly for the smaller calibers greatly increasing their effectiveness compared to back-in-the-day.

So, in handgun calibers-the ones mentioned in the title in particular—the temporary cavity damage from the bullet’s passage is not a reliable factor in wounding/stopping.

In addition, you could have, for example, a high KE RN Solid bullet that would do less damage in simply passing through and no deformation than a lower energy bullet that deforms and creates a larger channel.

I still vote 12 gauge. :)
 
You noticed that, too.
.380 sized 9mm bullets and 158gn .45acp?
Proof reading
For the record I've not shot any 45acp rounds less than 165 grains, with the exception of the civil defense no lead bullets of less than 165 gn.
I believe the article referenced ".380-inch" 9mm rounds rather than just .380 9mm. And: https://www.outdoorlimited.com/hand...rip-45-acp-158-gr-copper-trocar-hp-20-rounds/

Many of the more recent articles I've read on the subject of caliber seem to acknowledge how the genius of marketing has related caliber size to the size of one's ... 'hands'.

.380 acp and 9mm Parabellum use .355" bullets, 9mm Makarov use .363-365" bullets. None of them use .380" bullets.
His 158 gr. 45 acp bullet comment is likely misstated since 180-230 gr. bullets are much more common than a bullet of that size.
I enjoy reading about guns and related content but accuracy, spelling and grammar give me more confidence in the source. YMMV
