Does anyone know which has the grater amount of stopping power?
Check out the following
Handloads.Com - Stopping Power
No doubt a .38+p has way better stopping power.
thanks, that's definitely going to become bookmarked, but does anybody know about the joules (in general) of either bullet
To calculate energy (in ft-lbs, not joules, sorry) for any bullet:
Weight in grains * velocity in FPS * velocity in FPS / 450240
For example,
92 gr * 900 FPS * 900 FPS / 450240 = 165 ft lbs
158 gr * 1000 FPS * 1000 FPS / 450240 = 351 ft lbs
Ft/lbs don't stop an attack. You need a nice, wide tunnel through the CNS for that. The .38 Special is your clear choice here.
Regular load .38 special far outshines the .380.
Plus P .38 special blows it away, not even close!
A .38 special can "bury" the .380 ACP... if fired from a 20" lever action carbine.
My point?
Let's first ask the person... using which specific platform?
Too many answers and not enough questions.
Are we talking about comparing a Bersa 380 with an S&W ultra-lite with LESS than 2" barrel?
No part of a firearm stands on its own merit and the most important part is the person who uses it.
Has the person ever fired a 2" revolver with +p "kick hard but also rip your hand off" recoil?
It's the package deal we should look at. Imagine try to shoot a .45 ACP... using the "platform" of a KT 380 or the new Ruger LCP?
How many shots can YOU get off?
And would you hit or would you miss?
Just wanted to point this out to the original poster.
You still have other questions that need to be answered before you can get a fair answer on which one has a "better" stop.
Just my opinion.
Wow! And I thought all he was considering when he asked the question was, "assuming reasonable hits".
"Stopping power" is just a unit of measurement... not a tactical philosophy
You know who said that?
Evan Marshall... who literally wrote three books on stopping power.
And you know what he carries?
A Glock 26 9mm, a .38 Scandium J frame revolver and a KT P32.
This person who posted first here is a new member. Shouldn't he get "more" than the "stopping power" claim.
His or his family's life can depend on the answers he get here.
Again... just my opinion.
A .38 Special is a lot better than a .380 ACP. The bullet weighs almost twice as much, so it will penetrate better. The recoil is nothing to worry about. An alloy J-frame .38 is not hard to shoot fast. It doesn't break your wrist and rip the gun out of your hands. It just goes "pop!" and sends a bullet downrange. Anything with a short sight radius and a small grip will be hard to aim and shoot fast with.
That's just my opinion though, worth what you paid for it.

Run some 38 +P through a chronograph using a snubbie and tell me how much 'stopping power' it has. Most velocity and energy figures for the .38 are measured using a 4" barrel.
The last Winchester +P 158 grain SWC-HP ammo (the old "FBI Load") that I chronographed through my 2-inch S&W Chief's Special clocked 925 fps. Same box yielded 992 fps from a 4-inch S&W Model 10. Of course that was in 1996 so ammo may have changed.
Of course I'm old fashioned and feel the .38 Special is perfectly satisfactory served up in a 2-inch barrel when used with bullets of decent weight whether in +P guise or not.
I kinda hate to see the .38 Special round relegated to snubbies in the eyes of modern shooters. The round is more versatile and flexible than that. It's natural home is in 4-inch "service" revolvers and 6-inch target revolvers. I most often carry a 4-inch S&W Model 10. It's more concealable than many suppose. It also is great for range or field use. Other great .38 Special revolvers that should be put to use more often are the Colt Police Positive, Official Police, Diamondback, and Officer's Model, the Smith & Wesson Model 10 M&P, Model 14 K-38 Masterpiece, and Model 15 Combat Masterpiece, and the Ruger Speed Six and Security Six in their .38 Special variations. Any of these make great range, field, and home defense choices and the models that have 4-inch barrels can be concealed quite handily.
I've had far less field experience with Texas critters with the .380 than with the .38 Special but will say that the .380 pales in comparison in my view.
The 38 has a larger bullet and more powder in the case. You do the math. The 38 will deliver more Kinetic Energy then the 380. Kinetic Energy is what some refer to as "Stopping Power"
Quote:
Kinetic energy is the energy of motion. An object which has motion - whether it be vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) which an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object.
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine. And for a fourfold increase in speed, the kinetic energy will increase by a factor of sixteen. The kinetic energy is dependent upon the square of the speed. As it is often said, an equation is not merely a recipe for algebraic problem-solving, but also a guide to thinking about the relationship between quantities.
Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg*(m/s)^2.
