Re: +P vs Hollow Point

Yo guys. First time on this site. This thread was appealing. I just purchased my first handgun. I was in the military and loved the 9 mm so I recently went with the Sig X5. The salesman explained that I should have a magazine of hollow point and that i could also use +p. He didn’t really explain that so i also was under the impression they were mutually exclusive.

As I understand the attributes are different now, the question really is not this or that, as in +p or hollow point. The question is what does each do, on its own?

So am I hearing this correctly? +p are used for stopping power and hollow point are used to control collateral damage? So if I’m in my house and don’t care about what my bullet hits after it takes down the intruder, then I would use +p. It would have greater force and therefore more stopping power. Also these bullets will do more wear on my gun and will cost a lot more.

However, if I’m in my house and I care that my kids or wife or husband could be behind the intruder, then I would opt for the hollow point? It will flatten on impact and therefore has less penetration power and is less likely to travel through an intruder into my neighbors home. This type of round will cost more than normal 9 mm but not as much as +p.
Are those correct summaries? I suppose for completeness you could add what a +p hollow point combo is good for. I assume the ultimate home defense round? Stopping power plus collateral damage mitigation?
Get it out of your head that +P and hollowpoints are in the same category of things. Hollowpoints, also called "JHP", is a type of bullet construction. +P is a measure of case pressure during cartridge detonation. Generally speaking, cartridges of a given caliber have a "standard" pressure measurement for the caliber. Adding additional gunpowder to the cartridge increases the pressure in the case during detonation. So, take a standard load and increase the powder, and you have a +P load. Take a +P load and add even more powder, and you’ve got a +P+ load. OR.... take a standard load, but add a longer bullet that sits deeper in the case, and that can increase pressures to +P levels.

Exactly none of this has anything to do with bullet selection except in one way.... hollowpoints are almost always superior for self defense. They do more damage, and are less likely to overpenetrate and hit an unintended target. Adding more gunpowder to create a +P load with that hollowpoint might make it perform even better, or it might make it disintegrate after entering the target.

With rare exception, using a hollowpoint is the better choice. But your decision whether to use a standard pressure hollowpoint load, or a +P or +P+ hollowpoint load should be dependent on several different factors, including what kind of gun you’re using, in what caliber, for what intended purpose, and your personal sensitivity to recoil.

I am asking about the +P and Hollow point for defensive only, not range time.
You're most likely going to be using a hollow point, regardless of whether it is loaded to +P pressures or not. You have to get that important distinction into your head. Hollow point is a bullet type, abbreviated as "JHP" for "Jacketed Hollow Point." The term +P refers to the pressure generated by the cartridge when it fires a larger than normal load of powder. A +P, or +P+ load has more gunpowder in it, and will generate higher pressures, and therefore higher bullet velocities, than the same bullet loaded over a standard load of powder.

It's like your asking "should I put high octane gas or bananas in my car's gas tank?" ...when you should either be asking if high octane gas is preferable to low octane gas, or asking whether bananas are better than apples. The two categories are really unrelated.

Now, if you want to know whether to carry +P 9mm ammo or not, begin by assuming that you'll be carrying hollow points, regardless of whether they are +P or not, and then ask yourself whether or not you really think you need the higher velocity of a +P round. That's a call only you can make. Just be aware that shooting them is harder on your gun, and they tend to be less pleasant to shoot for practice purposes.

I only use +P ammo in one of my guns, and that is a S&W 642, because the .38 Special cartridge is a little bit anemic compared to some other cartridges — particularly in a 1-7/8" barrel — and therefore a +P load is likely to perform better. OTH, all my other carry guns are in .45 ACP, and while +P ammo would probably make them more lethal, standard pressure cartridges with proper bullet design and plenty lethal already in that caliber, and they don't beat the gun up.

http://en.wikipedia.org/wiki/Overpressure_ammunition
Understood, but I've never seen an FMJ loaded to +P pressures because +P ammo is generally used as self-defense ammo and FMJs are primarily (but not always) used for practice ammo. +P ammo tends to beat up guns, even guns that are rated for +P pressures. Over time, shooting a steady diet of +P ammo and nothing else will decrease the life of your gun. That's why most people never practice with it, except to run an occasional magazine of it through a gun to familiarize themselves with how it feels to shoot it.

Re: +P vs Hollow Point

As far as I know, most +P ammo is hollowpoint.
