Best SD Load for 9MM?

And you have NO idea......

FWIW, from page 11 of the M&P owners manual:

• "Plus-P-Plus" (+P+) ammunition must not be used in Smith & Wesson firearms. This marking on the ammunition designates that it exceeds established industry standards, but the designation does not represent defined pressure limits and therefore such ammunition may vary significantly as to the pressures generated and could be DANGEROUS.

You have NO idea how much overpressure a round has and there is no limiting cap on the pressure.
 
Federal HST, Corbon DPX, Gold Dot, any of these will do plus others.

I'm a 115 grain man myself... ;)
 
One little note;

Make sure that new pistol gets about 200 rounds through it to
break it in before you start any of your SD test.... maybe more?

Even rifles and shotguns need to be broke in before they settle down and start to group and cycle smoothly.
My Beretta 391 12 Ga. needed WD-40 the first two weeks for it to feed the next shell in some times, when it got dry.

Good shooting with the new pistol.
 
I believe that the best load at present time is the Federal 124 gr +P
HST round according to the "experts" and gel test results. So I decided
to buy some, hmmm...easier said than done so others must think it's
good also. After a few months wait sgammo.com notified me that they
had some in stock again so I quickly ordered 200 rds. Velocity out of
the short barrel of my Glock 43 of 1135 fps was a bit higher than
expected. I can say that a two ltr. plastic soft drink bottle filled with
water will give you a shower if you hit one with the HST round from
10 ft away and a couple of the bullets dug from the ground of my
back yard remind me of the Winchester Black Talon ammo hated
by the media. I don't know if the're the very best but you could do a
lot worse.
 
I don't want to ruffle any ones feathers but..........

I tested the 115 and the 124gr 9mm Gold Dot loads and did have..................
a failure to feed/eject with one of them.

One reason to test just more than 20 rounds to see if they will work in your weapon.

I reloaded both weights with shorter and longer OAL than the factory bullet with store bought bullets, to see if there might be an improvement, using medium and slow powders.
(Alliant powder was not used due to case volume in the short OAL test......just ball type powders were used.)

NOT !!

Speer has the correct OAL for this bullet design.

I might retest the half of a box again but right now I am happy with another companies loading.

Stay safe.
 
A lot of major departments use Gold Dot in the 124+P flavor. Others like the Federal HST.

That said, given the improvements in modern ammunition, just about anything you find by the major ammo companies will work well. You just have to put it in the right place. Look around to see what you can find locally at a decent price.

On general principles I don't buy from boutique ammo makers. Given the design specs (10 inch max penetration), I don't believe Critical Defense by Hornaday has sufficient penetration.
 
A friend of mine is a police chief and he gave me (4) 50 round boxes of 9mm LE ammo because his department switched to .40S&W. Half were Gold Dot 147gr, and the other half were Winchester Ranger T, also 147gr.

Best Choices for Self Defense Ammo

Try some of the recommended 9mm rounds, and choose the one that you shoot the most accurately with your new Glock.
*
That page is based on the work of Doc Roberts, by far the leading expert in the wound ballistics field today. (And the only exception to my rule about avoiding ARFCom to avoid the soul sucking stupidity there.) Buy a bit of each of the choices that are available to you easily, test them for shootability and accuracy in your platform, pick one or two you find workable, and then buy a case (1000 round minimum) of it. Put 500 rounds through the pistol w/out a malfunction, clean to taste, lube appropriately, holster up, and drive on.
 
In my 9's, I generally practice* with 124 grain FMJ NATO surplus and use Remington 124 grain Golden Saber for self-defense. That said, I practiced with the "new" Winchester 147 grain Train & Defend ammunition, which I'm pleased to say, lives up to all the hyperbole.

*I'm becoming less and less enamored with the 9mm and pretty much just shoot .38 Special and .45 ACP. I'm leaving all that polymer bull****:D behind without any sadness or regrets. YMMV
 
I have had various jams using hollow point ammo in various semi autos over the years. My Ruger 1911 eats everything and has never jammed. My Colt 1911 eats ball ammo without a hitch ever, and it is very accurate, can't say that for hollow points in it. I carry ball in the Colt when I carry it. The Ruger is loaded with hollow point. Just gotta have that sense of comfort in what you carry and the ammo you use. Pistols can vary from one to the next. Best to shoot a lot of what you intend to carry and find what works flawlessly. Good luck.
