.357 Sig Question
#1
Hey Guys,

In terms of ballistics (inflicting the most damage to a "threat") is the .357 sig more "powerful" than a 9mm and/or .40 cal? Also what is recoil like compared to a .40 cal and 9mm? Assume I was comparing the G19, G23, and G32 since you can use the same caliber but have different "felt recoil" due to firearms with various features: steel frames, polymer frames, recoil springs, etc. Thanks fellas!

"More powerful"

Well they are fast 9mm bullets. really fast. So I guess in that regard, yes a 357 sig bullet of the same weight out of the same barrel length is going to have more energy than a 9mm including +p and +p+. How much more depends on the manufacturer and how much to the rounds ability its loaded to.

It does recoil more than a 9mm, more like a +p++IMHO.

As to the 40 s&w, energy can get pretty close. There are hot light grained 40s that zip along and can put up pretty good numbers. That one is a toss up to me, as you have speed vs diameter.

I prefer the recoil impulse of the Sig to the 40 in guns that I own 2 barrels for.

One issue with the Sig is sound and muzzle blast. It is a LOUD round, and some folks don't care for that. I have had people move over a lane in an indoor range when shooting mine.
I swear, by my life and my love of it, that I will never live for the sake of another man, nor ask another man to live for mine.

Comparative ballistics. Note identical bullet weights:

Winchester 9mm+P+ SXT 127gr JHP: 1250fps

Buffalo Bore/Underwood/Doubletap 9mm+P+ 124gr JHP: 1310fps

.357 sig original loading, 124gr JHP: 1400fps

.357 Magnum legendary Federal 125gr SJHP: 1450fps

The 9mm listing is maxed out, but you can drive both .357s a good deal faster with handloads or with specialty ammo like Buffalo Bore.

I think .40 S&W is quantifiably inferior to 9mm or .357 sig, I think it's a stupid compromise caliber that fails to do anything better than either of the rounds it's trying to replace- but which recoils more than both.

Thanks for the input! Right now most of my money is going into my AR and a few other things (expanding my education, picking up some stuff for a future business, etc.), but if I ever buy another handgun then I might want to get a .357 sig. I know my next handgun is going to be a full sized model and that is meant to be a great range gun and OC gun. In other words, maybe a Glock 31 gen 4.

Personally, there is so little difference in the performance between top end 9mm+P+ and typical .357 Sig that IMO there's just no reason to give up the extra capacity of the 9mm, nor deal with the extra blast and recoil of the .357 sig. I think when you bump up to full power .357 ammo, the blast and recoil are excessive.

I think that among the legacy calibers, 9mm is still the king of the hill. Which is why every military on earth that hasn't switched to a PDW caliber is still using 9mm. An exception is suppressed work, where the .45 ACP really shines.

Again: Just my opinion...but a fella can lay out a lot of hard data to back that opinion. Wink

This is just some generic observation I have noticed by looking at published data for various 9mm, .357Sig and 40S&W.

In similar bullet weight, say 124 for the 9mm and Sig and 135 for .40, the Sig runs all over the 9mm.
Average for 124grn .357Sig is between 560 & 580 ME @ approx 1450FPS
Average for 9mm+P is about 470ME @ approx 1300
Average for .40 in the same weight class (135) is about 525 @ 1300

If I were only to have one handgun and was looking at stopping power and capacity I'd go with a 10mm G20 or Witness, followed by a Sig 229 in .357 SIG and then the 9mm (capacity) and then .40.

My 229 in .357 was very "easy" to shoot, recoil was not anything to moan about at all.

When it comes to 4 legged animal defense, i think .357 sig/magnum hold a BIG edge on even the hottest 9mm. But for people, i just don't see it. 90fps is not a huge difference.

I would like a FN Five-Seven, but I can't bring myself around to dropping $1,000 on a pistol just yet. I all ready have a .380, 9mm, .40, and .45. I think the .45 GAP is a stupid round, but I've seen some gel tests from a .357 SIG and was quite impressed. Back to the .45 GAP, the full sized model (G37) only holds 10 rounds, and my Glock 30 holds 10 rounds of regular .45 acp. I understand the G37 has a smaller grip, but still holds a "large diameter bullet", but for the price and popularity of the ammo, I rather own a .45acp or .40. I really don't want to get a 10mm either because on the 10mm thread it was discussed that the factory loads aren't filled with enough powder or good enough powder for the 10mm's true potential.

Sorry, I have to disagree, over 100lbs ME is not a little difference IMO.

I don't have tons of experience with .357 Sig other than my 229, but I don't think it's that bad.
Maybe a Glock might be a different animal?


But still, that all said, for now my EDC is a 9mm, until I pick up a G20 this spring, or possibly a G29.

Unless of course you are shooting montana gold 115gr jhp for um special penetration. I am gonna stick with Sig on that round.
