I think if you are slitting hairs, 124gr
ammo is a little more reliable feeding in most 9mm pistols. And if penetration is adequate, it is still where you put the bullet that counts

I've been shooting HST 124 standard pressure loads in my G26-5 and my G43. It's worked well but when I went to re-order, my vendor only had the +P 124s or 147.

Any advice on which load might be best for my guns? Do they perform equally well, in terms of reliability?

Stay away from +P. To much recoil for no gain. Hst 124 or 147 is the choice.

Some here might find the following to be of interest.

Recoil of +P and even +P+ is not that much more than standard pressure to me, but recoil is one of the most subjective things in shooting. When I used a .40 a lot more than I do now, I found the recoil of the hottest 9mm to be roughly equal to the lightest of the .40 S&W duty loads, the subsonic 165 grain, in the same full-size Glock platform.

Looking at institutional experience, some departments have been happy with standard pressure 147 grain subsonic (i.e, Portland Police Bureau, LAPD, LASD) and some have not. LVMPD, CHicago PD,Jacksonville (FL), and NYPD (early Transit and Housing Authority elements) were not happy with 147 subsonic, went to 1124 +P Gold Dot, and reported much better results from their 9mms.

If you go standard pressure, definitely go with the more modern designs (HST, PDX-1 or Ranger, etc.) Personally, from slaughterhouse to street results, I'm still more comfortable with 124 +P and 127 +P+.

Best,
Mas

FWIW,
When I contacted Speer to inquire about the difference between their 124gr GD +P and 124gr GD “Short Barrel” +P, Technical Supervisor at Speer told me that their “Short Barrel” version is loaded “hotter,” so the projectile would still reach the optimum velocity for proper expansion after going through a short barrel of less than 4”.

Along with Massad Ayoob’s expert opinion, this is also something to consider when considering effective self-defense ammunition for sub-compacts....

Back when I worked at a LGS/Range, it was astonishing how many times people came out of the range and needed "hollow points" because they had literally just shot all their carry ammo. Much of this was during ammo frenzy times so the pickings were slim.

In today's supply situation, I can't imagine not carrying the exact round I want. Don't shoot the last of the good stuff before ordering replacements. While Glocks are usually very forgiving on new ammo profiles, I prefer to know my particular gun will feed when I need it to.

In 9mm HST, my choice would be 124gr non +P. If I had to wait a month or two to order, that'd be OK.

 

[Master Guns]

124 +P in my 19.4 and 43. Difference in muzzle flip is.negligible with the stress-fire grip, and the added velocity is useful with (a) shorter barrels, and (b) added clothing layers in cooler climes.

YMMV.

How is it useful? Can you give some detail please

Ayoob has been on and off the bandwagon so many times it’s ridiculous. He is played out. Go with standard pressures.

 

[cheygriz]

Of your choices, I would choose 147 +P every time.

 

[GlockFan7]

I carry HST 124 or 147 standard pressure, but prefer 147.

 

[E.Bar]

I settled on 124gr standard in both my 43 and 19, though I would be fine with any of them. Plus P gains you about 50fps and increased expansion, but if I read the gel tests right the standard pressure loads actually penetrate deeper. Thats the reason for my choice.

More propellant produces more pressure resulting in higher velocity. Higher velocity helps assure full expansion and adequate penetration. Since those two forces are diametrically opposed to one another, and since the muzzle rise and recoil of a 124 gr. +P are negligible to me, it is my preferred round (a) when using shorter-barrel firearms given energy dissipates more quickly than in longer barrels, and (b) if needing to defend my life against BGs wearing multiple layers of clothing in the cold clime in which I live.

YMMV.


P.S. Thanks for your service.

Thanks. Penetration is key. Accuracy is final. HST is awesome in any flavor

 

[GlockerBill]

All will be in the same ballpark in terms of momentum, but I prefer the heavier bullets for penetration. I also shoot a suppressor, and the heavier slower 147s stay under the 1100 fps speed of sound.

 

[fredj338]

IMHO, +P ammo is a no go for me in my G26. Too much muzzle flip and increased recoil - I have doubts about the increased powder load has a chance to burn in such a short barrel. I shoot 124 grain JHP in mine, no +P.

FWIW, I shoot 124 grain +P in my G19.

Regardless of bbl length, highest vel will be achieved with slower powders or higher powder charges used in shorter bbls. You just get more blast.
I like +p ammo in my g26, 124 or 147, HST.

Add'l vel aids expansion & momentum for penetration. Useful in shorter bbls where you are losing vel with std pressure loads. The HST is pretty foregiving as to exp when vel drops, but Other jhp, even 50fps can cause a failure to expand.

 

[10or45]

I choose heavy for caliber usually, especially in short barrels. 147 for me

147gr ranger t & hst have a good rep with several lea out here. I am fine with 124 or 147, but do like +p in shorter bbls.

146gr tanger & hst have a good rep with several lea out here. I am fine with 124 or 147, but do like +p in shorter bbls.

I'm not a big fan of +p but in a short barrel Glock I also prefer them. I agree they do help make up for lost velocity in shorter bbls.

 

[BBMW]

These might be useful

And I'll throw in one the OP didn't ask for...

 

[1L26]

Just purchased some standard pressure 124 HST for my BHP. Hopefully, this is the right way to go!
