Glock 31 Versus Glock 32

[Tzvi]

Which of these handguns would you prefer?

The Glock 31 has a longer slide than the Glock 32, would this help absorb more recoil than the 32? I understand the .357 SIG is a hotter round. And the 31 is out in the Fourth Generation.

The 32 is lighter, more easily concealed, and can fit many roles. It can use the 31's 15 round magazine, too.

Both of these pistols I imagine are in use for law enforcement. So, what are the opinions on these two Glocks?

 

[Apocalypse-Now]

the FBI and Dr. Gary Roberts both tested the 357sig round and found it penetrated identically and also had identical wound cavities as hot 9mm jhp's. the extra energy it imparts is pointless in terms of stopping power. they concluded when compared to 9mm it has less capacity, much more muzzle blast and noise with no advantages.

i would just get a gen4 23

Is the 357 Sig bad? NO! It is a very reliably performing 9mm bullet, but it is does not offer significantly better terminal performance compared with the best current 9mm ammunition. When firing through heavy clothing, automotive steel panels, automobile windshield glass, interior wall segments, exterior wall segments, and plywood, both the 357 Sig Speer 125 gr JHP Gold Dot and 9mm Speer 124 gr +P JHP Gold Dot exhibited nearly identical penetration and expansion results THROUGH ALL THE DIFFERENT BARRIERS, as demonstrated by both our testing and that of the FBI. Most 357 Sig loadings, unless the fail to expand, do not offer excessive penetration; in fact, the exact opposite, under-penetration, can be a problem. Several .40 S&W and .45 ACP loads offered superior terminal performance through barriers compared to the 9mm and 357 Sig loads. In addition to having tested virtually all the handgun ammo available in lab settings, we have also had the opportunity to analyze numerous OIS incident forensic results and have not observed any greater incapacitation in actual shootings with users of 357 Sig loads compared to those users of 9 mm, .40 S&W, or .45 ACP who are using equivalent modern, well engineered ammunition.

I have a G32. It's NOTICEABLY more accurate, faster, and overall a better round than the standard 9mm and 9mm +P. I disagree about the damage assessment of a previous poster. The 357 SIG round is a devastating projectile which imparts a plethora of damage profiles, all of them good to excellent.

A hundred feet or a hundred yards, the round will get the job done at a high velocity impact with very little gravity drop. It's not hard to shoot either.

A terrific pistol and round. Shoot one and you will come away a believer.

 

[Tzvi]

Ah, very well then. Glock claims that the 31 can penetrate 'light armor', leading me to believe it performs similar to a +P or +P+ 9mm. Thank you for the information.

 

[Tzvi]

I do understand that the .357 SIG is supposed to be accurate at a long range, but is it all that much more accurate?

you're welcome. glad i could help you avoid this pointlessly expensive caliber.

I do understand that the .357 SIG is supposed to be accurate at a long range, but is it all that much more accurate?

the bullet drops at a slightly slower rate than 9mm does at distance, but since most pistol fights don't take place at 100+ yards, so it's not something that'll ever be an advantage for you.

 

[Tzvi]

Glock's "Penetration" Claim?

I'd conquer with that. You really don't need a 'long range handgun'. But, Glock does claim that it has the highest penetration of the Glocks along with the G20.

 

[Tzvi]

Conclusion?

And I know the overpressure 9mm is capable of that, too. but is the .357 SIG any better at armor penetration than the overpressure 9mm?

hmm, where did you see that claim? it's not on glock's website. 357sig users incorrectly make that claim. lol

 

[Apocalypse-Now]

And I know the overpressure 9mm is capable of that, too. but is the .357 SIG any better at armor penetration than the overpressure 9mm?

no.

glocks can handle +p and +p+ 9mm all day long. the gen3 357 sig is the exact same as the 9mm glock except for the barrel, extractor parts, and mag. even the recoil spring is the same.

the gen4 31 as a heavier spring to reduce frame spanking and recoil lol

 

[Tzvi]

Concluded...

Now that you think of it, I am wondering where I saw that! Thank you very much, the information you gave me is very helpful.

 

[Apocalypse-Now]

you're welcome again my friend!



357sig fans will be here in the morning to regale you with the tales of local pd's stories of amazing one shot stops with 357sig lol.

 

[breacher]

Tzvi- do your own research, the 357 Sig is racking up an impressive record of one shot stops in the LE community. I have personally seen less than stellar results in 40 cal shootings with the Glock 22's. I switched to the Glock 32 on my own dime.

 

[Apocalypse-Now]

did i call it? lol


where's your proof of this "impressive record"?

you can read all about the FBI and Dr. Robert's scientific data (including actual shootings) with 357sig.

 

[R.W.Dale]

I carry the 32 and have been known to carry a 9mm 34 on ocassion.

The assertion that 357 sig brings nothing to the table is blatently false. Even with a shorter bbl my 32 will launch 124g bullets easily 200fps faster than the long slide 9mm. This is what allows for the rounds fantastic barrier penatrating ability and that's probably why the secret service adopted the round

So look at it this way, any run of the mill 357 sig load is like getting the highest performance subgun +p++ 9mm ever loaded plus another 100fps sprinkled on top just for good measure.

To assert that 9mm is good enough then let me counter that with the question. Why bother with 40 then?

Back to the op's question. The g32 is wonderfully shootable and is in no way taxing to shoot compared to even a full sized 9mm. The good thing about glock is if you decide you want the higher capacity all you need is a g32 mag and a grip extension sleeve. Which is what I recently did.

Should just get this out there for the benefit of us all and before it happens... Let's not start a fight here!

again, proof?

the FBI has the most stringent ballistics test. the secret service is also known to carry armor piercing ammo in addition to jhp.

lol just a friendly debate. hopefully i didn't get the 357sig guys riled up lol

 

[Tzvi]

I guess for some it is an interesting and informative debate.

not really a debate. it's basically scientific data vs. a few local police officers claiming amazing performance lol

 

[R.W.Dale]

OK lets assume that you're correct that terminal performance is identical to 9mm .

Well in that case its all good because 357 sig's higher mv will allow it to match 9mm's performance at the muzzle much farther out and again will provide superior barrier penetration at the same time which is almost purely a function of velocity.

To claim that its no better because the wounds are similar pays attention to only one aspect of a handgun rounds overall performance and ignores everything else.

since the performance is identical at 10, 15, 25 yards as test by the FBI, why would the performance be better at longer distances? regardless, it's a rater moot point, since most encounters occur 7 feet or less.

 

[Apocalypse-Now]

ooops. double post

 

[R.W.Dale]

Here's a rather nice test that clearly illustrates the 357's ability to shoot through things

http://intrencik.com/357sig.htm

Any way you look at it the advantages are indeed there. It's up to each individual to decide if they're worth having.


For me they are. With active shooter incidents on the rise. One of which was very close to home for me. I'm no longer banking on every engagement being a point of contact scuffle in the dark.

Now would you please start your own thread to discuss this further rather than impolitely detailing the OP's thread about shootability between the g32 and 31
