9mm +P vs standard load

Sorry for the newbie question; I just picked up my new sr9c and should be getting my ccw permit in the next two weeks. My questioin is what is the difference between 9mm+p load vs a standard load, and does it really make that much of a difference? Also what are some opinions for those of you who have an sr9c. I am leaning towards a 124gr JHP round. Looking for some advice please.

people will surely stop by to quote speeds and energy... but for all practical purposes; no.
there are great arguments to be make either way though.

that being said -i do like Gold Dot Short Barrel ammo, which in 9mm and .38 are both +P (there is no non+P version in those two calibers).
but, if this makes any sense, i primarily like them because; i love gold dot bullets ( i use gold dots in all my guns), and it's designed for short barrels. but not because it is +P (it just happens to be +P).

i honestly can't tell the difference, unless i was deliberately trying to tell the difference, between +P and non-+P, as far as factory self defense ammo is concerned.

I am of the opinion that if you "need" the +P version of a round,
you actually need the next step up in power from what ever caliber you have.

The 9mm +P will produce slightly better performance than a standard 9mm, at a noticeably higher cost.
It is also incompatible with some guns (look at the owners manual for specifics on your gun).

If you are an LEO and have a .45ACP then carrying +P is not as much of an issue, because the next step up from .45ACP is a 10mm and many departments will not allow officers to carry 10mm.
.
.
.
.
And then there is always the "shot placement" argument.
A properly placed standard load will produce better results than an improperly placed +P.
Thus if you can use less expensive and perfectly functioning ammunition, you will probably practice more.
More practice increases the likelihood of proper shot placement.

You dont want to use +P ammo for range use... only for self defense, as it puts more stress on the weapon and can lead to premature wear / breakage if used regularly.

I fired a few 124 gr +P rounds in my XDm 9 and I like the performance of them over the 115 gr standard rounds... next up for me will be the 147 gr standard rounds.

I carry 147gr. standard pressure jhp. The +P is a personal choice. It really does not make much of difference. All modern ammo will do what it claims. While most guns will shoot +P, it is true it increases wear.

buck ... in terms of a direct comparison, the 9mm +P cartridge is simply loaded at an increased PSI of 10% (38,500psi vs the standard 35,000psi per SAMMI pressure specs). The real questions that I would suggest that you ask yourself here is:
1. Will that additional 10% pressure and subsequent effect on momentum & penetration help you achieve a better self defense result (keeping in mind that there are many other factors that will also impact the effectiveness of a SD round including bullet weight, material, shape, etc.) ... and
2. Is the additional expense worth it.

While both of these questions have been debated extensively over the years and a good case can be made for either, the answer for me personally was no. After researching this issue until my head hurt a few years ago , I finally decided to go with a standard pressure ammo in both my 9mm & .45acp carry guns (Winchester Ranger JHP in 147gn for my 9's and 230gn for my 45's - YMMV). I also found the following momentum chart (by Iowegan) very helpful in reaching my final decision Ammo Momentum and Energy Chart. Hope that it helped ... Good luck with your decision

+P is a waste to shoot nothing but for practice. A few rounds are fine but just know sometimes the standard stuff is just as hot so do the research.

I also don't agree with the comment you need a larger caliber if shooting +P. If you are going for expansion of a hollow point sometimes it requires a +P rating to do it's thing. Sometimes the bullet fragments... View some YouTube videos of grain bullet you like and expansion results. If you see one that expands and stays together nicely but is a +P don't hesitate in using them!

Andre has about the best collection of said videos I know of:

YouTube - andreleger2001's Channel

I personally use and have for my 9mm the 147gr Winchester Ranger-T's. The talons on these things will tear things up for sure! Law Enforcement uses them and here is a 127gr +P+ video:




Other videos out there of the 147gr

The RCMP up here use the 147 gr Ranger bullets illustrated in the above jug test if that means anything to you. The choice was made after extensive testing involving such factors as penetration and expansion.

None of the handguns typically carried are death rays and most say shot placement is everything. If it were me though I would be carrying a CZ 75D Compact over the Ruger but that is just me.

Take Care

Bob

This is certainly a "loaded" question, pun intentional. And there is no one correct answer. If you get 10 posts on this thread in response then you will probably get 10 different answers.

Some are of the opinion that momentum is a more important factor in a round's ultimate performance if used for real business. That will (generally) give better penetration in a BG, and some maintain that after shot placement that is the single most important factor. And in the momentum category you usually get higher numbers with heavier rounds.

Others think that with shorter barrels of compact guns you need the lighter +p rounds to get up to speed quicker and get more energy on the target, and hopefully impart enough velocity for the hollow point to expand properly.

But to further muddy the waters, sometimes hollow points don't perform as advertised, especially when the hollow point cavity is filled with cloth after hitting heavy clothing, and they have little or no expansion.

So there is no single good answer, other than whatever round you use must be absolutely reliable with your weapon. After that, you must be acceptably accurate with it. After that, its really anybody's guess as to which is better.

+P ammo is generally more expensive, so you should balance out the fact that you will be able to practice with standard pressure ammo more frequently if your budget is limited as is usually the case. Plus the standard pressure rounds will not wear on the gun as much.

as others have said it's loaded to 10% higher pressure. this usually adds 70-100 feet per second to the bullet. IMHO this isn't a bad thing, but by the same token a gun that's not +p rated is not a deal breaker to me either.
I use either 124+p golddots or 147 standard pressure depending on which of my 9mms I'm using.

well...i am a fan of heavy per caliber, ive done the math, the comparisons and so-on on a hefty list of sd rounds. from the dismally preforming Powerball's to +p+ 147g Buffalo Bores....when the +p 124g rounds are pitted against a typical 147g round, the knockdown numbers are tied...so the reason i say heavy instead of hotter is because the 147g's have less pop and are easier to control than a +P or +P+ round. the damage done to a gun from using +p rounds on a regular basis is dismissive...any well made auto should be able to throw a box down range without fail...really just do the research find what fits and most importantly WHAT YOU CAN HIT WITH.

i use 147g Hy-Shocks...not hst's, the original hy-shoks...numbers have backed them up and they function flawlessly in my gun.

You may want to call up a few manufacturers before you make that claim... Springfield for one does NOT recommend using +P rounds on a regular basis, yes their weapons are +P rated, but that doesnt mean you should use +P all day long either, they are for self defense / hunting, NOT range use....

Thanks everyone for the different advice and opinions. I picked up 100rds of Winchester 147gr Ranger T's JHP for a great price so I will be testing these out first and seeing how the sr9c handles. Thanks again!
