40 S&W VS. 357 SIG (part 4) (FMJ WOOD TEST)

Penetration test between the 40 S&W, and the 357 SIG. Targets were 1
) 4"x4" wood post, 4) 1"x6" red cedar boards, and 1) 3/4" piece of plywood.
Rounds used were, Winchester White Box full metal jacket
40 S&W-180gr.
357 SIG-125gr.
Firearms used were,
Smith & Wesson M&P 40 Pro Series 4.25" barrel, and
Smith & Wesson M&P 357 4.25" barrel

This is probably one of the simplest and best demonstrations on penetration for different calibers.

[@ThePenetrationChannel]

[@bobbyjames1714]

The 357sig is a beast, im starting to feel like it's the best defensive handgun round.

[@ThePenetrationChannel]

Bobby James It's definitely a beast of a round. I carry 9mm merely for the extra 2 round capacity. And I keep my 357 sig in the case since it is no longer made in the M&P line. I am very fond of the 357 sig, and it is the most accurate of my M&Ps with me behind the trigger. Thanks for watching.

[@bobbyjames1714]

The Penetration Channel My defensive auto's are 9mm and 45acp but thanks to your videos, I got to convince the wife that I need another handgun. Keep up the good work brother, we need these penetration test. Everybody has gel test but few are doing barrier test like yours.

[@12c40]

The Penetration Channel I have an 357sig M&P full size . Got it in 08, don’t shoot it at all, what do you think about keeping it in my safe. Got my ccw permit with it about three years ago here in Illinois. Maybe 500-600 rounds through it.

[@IamKILLASWAGG]

The reason I carry on and off duty the .357 sig. Great penetration thru solid objects, and excellent stopping power and ability in soft targets.

[@ThePenetrationChannel]

Glimtech Arms Couldn't have said it better myself. Thanks for watching!

[@SINESTERSERPENTSIXXX]

i personally prefer the fact that the 357sig has a high capacity, is a very flat shooter. the penetrations a big plus. although the draw back would be over penetration and collateral damage. i have been carrying a 357sig for 10 yrs and don't ever see myself changing.

[@tmager2545]

I really enjoy that your channel does alot of head to head comparison with comparable rounds. Too many channels out there are comparing apples to oranges

[@n300zx931]

lots of people will think the 357sig will over penetrate. hope they understand that a hollow point round would have very different results.

[@ThePenetrationChannel]

True. The 357 sig was designed for better barrier penetration performance, and I wanted to demonstrate that capability. Hence using fmj rounds. I personally would rather have a bit too much penetration than a bit too little. When using hollowpoints, the difference in penetration between these two calibers is minimal. Thank you for watching!

[@CheifDegenerate]

n300zx931 that's true and false at the same time. most manufacturers today have (for lack of better Terminology) "watered down" the 357 Sig. and have had to slightly redesign the bullet. early hollow points still over penetrated because they tried to make them just like 9mm. but they often clogged giving them minimal expansion and thus over penetration. though many brands these days have tamed them to still beat many barriers and still stop within desired FBI specs using gel. however, these calibers still grossly over penetrate (in comparison to 9mm or 380 auto) when fired into parts of the body with less resistance such as the stomach or into the thigh missing the bone. That has always been and will always be a danger of larger bore calibers and higher pressures. I'm not an advocate for any caliber being better than another. my actual theory is the more diversity out there the better. I am often left only being able to carry a 32 auto, and with Lehigh Defense creating the Xtreme Cavitator i feel more comfortable with it. if 357sig ammo was more affordable, and more plentiful in my area I'd probably find myself carrying my Sig P239 more often. Though I wish Kahr made a 357sig (especially in their K series) I'll settle for what I have. I may have to set out and see the difference of my 357 Sig ammo like he displayed here (my P239 having a shorter barrel may have different results) but I'm going to try between JHP, FMJ, and my Lehigh Defense Xtreme penetrator and Xtreme Defense ammo. time to line up somewhere to go shooting!

[@SINESTERSERPENTSIXXX]

the difference is minimal? 2 inches of wood difference is minimal?

Man , ..............I'm totally blown-away by the results of this penetration test ! I own just about every handgun caliber there is , and although I really like the .357 Sig , I was betting against-it . I didn't think it would make it beyond the 4X4 piece of wood . I thought the "40" would make it over the finish line 'cause of the weight & momentum . I used to like my Glock 31 ; now I LOVE-IT !!!!

[@tonyorob]

wow i didn't realize the difference in performance would be THAT significant...great vid

[@ThePenetrationChannel]

Both rounds are sufficient for personal defense. I do tend to lean towards the 357 though.

[@tonyorob]

+The Penetration Channel i have both calibers and which one i carry on any given day/night depends on whichever one would likely fit specific self defense scenarios that i could possibly encounter while i'm in different enviornments. For example: the times i go to dept. stores, malls or any place where a mass shooting could take placei'll take the 357 SIG or a 10mm. Any other place where i'd likely have to defend against a more personal attack i'd likely have my 9mm, 40 or 45.

[@ThePenetrationChannel]

+tonyorob sounds like good logic to me!

[@gymreaper1728]

[@caseyterrence1606]

Sorry that the .357 Sig never took off in a wide sustained acceptance by military or police departments. It is one hard hitting fast round that can do the job expected from it. Just about every publicized test that I have seen puts it ahead of 9mm, and just behind 10mm + .357 mags. Ammo is hard to find and expensive but I would trust this cal. in defense of home and family.

[@charlesdickens8599]

Winchester white box is a very weak loading of the 357 sig. If the load does not achieve at least 1450 fps, then the test is not really testing a valid loading of the round. But this was interesting anyway and showed the anticipated results; the sig is a really good hard barrier penetrator.

[@robertciaschini7625]

The Beauty of the S&W compact 2.0 40 cal is that I just found out I can fire the Sig 357. Ironically, I purchased the Sig 357 Winchester white box for my Taurus 605 poly snub nose by mistake. I picked up my 40 cal Saturday. Who knew? Not me. But, I can shoot the Sig 357 rounds and compare to 40 cal. Great video!

[@boedude8496]

the 40 180gr is heavy for caliber, a 155gr would be a more equal comparison. you are comparing a slow and weak 390 energy round with a good fast 500+ energy round. obviously in this scenario the 357 will perform much better. underwood ammo would provide a much better comparison, keeping the bullet weights comparable.

[@ThePenetrationChannel]

boedude I should have the Underwood ammo test video up this weekend. I have the 140 gr. extreme penetrators for the .40, and the 115 gr extreme penetrators for the 357. can't wait to do the test....Stay tuned.

[@SINESTERSERPENTSIXXX]

506 lbs at the muzzle from a 4 inch barrel.

[@JohnLloydScharf]

180 grain is the most common round for .40 S&W. At 125 grains, the .40 S&W maxes at about 469 ft/lbs compared with 564 ft/lbs for the .357 sig At 180 grains, the .40 S&W maxes at about 520 ft/lbs compared with 524 ft/lbs for the .357 sig At 140 grains, the .40 S&W maxes at about 415 ft/lbs compared with 568 ft/lbs for the .357 sig

[@JohnLloydScharf]

In all cases, a .357 magnum from a 6" barreled Desert Eagle has less kick with more energy/velocity.

[@sethstidams6358]

boedude heavier bullet will penetrate more

[@linkbond08]

I shoot all 3 (9mm\.40S&W\357sig) Out of my M&P.40 with conversion barrels, the 357 has the most overall power and penetration in wood, water jugs, and varmints.

[@GunsHarleysUSA]

Try using the 135gr .40 S&W instead of the 180gr. I think this would be a closer match of the two rounds and so would the outcome.

[@thebeastofyoutube1064]

Being a person who shot a 40 and a 357mag (I know it's not 357sig) accidentally with no ear protection, I would take a heavier slower subsonic bullet any day of the week in case I have to actually use the gun for self defense. Last time I forgot to put on earbuds with my .357mag, it took 3-4 days to actually hear again in my right ear, I have tennatis now.

[@squideye1144]

you let the results do the talking,not personal opinion excellent job.

[@ThePenetrationChannel]

Thanks for watching.

[@nil981]

if my understanding of ballistics (with relation to bullet design) is correct, than in terms of penetration, the smaller, faster bullet retains its power over longer ranges and penetrates deeper. The slower, larger bullet has more penetration and power at closer ranges but loses its effectiveness at longer ranges. so the .357 sig would be better at penetrating cover due to its higher muzzle velocity, if a police officer is in a place where theres a lot of cover criminals can exploit. The .40 s&w would be better in tighter spaces inside alleys and buildings where its lower velocity and lower penetration are ideal for police officers raiding a building where collateral damage cant happen. so, irrespecitve of ammo cost, i can see a well reasoned case for both the .40 s&w and the .357 sig.

[@moeynola6747]

wow awesome testing..i was sitting here with my new sig sp2022 40 and saw they have a 357 sig barrel conversion..after looking at both rounds online side by side I thought that there wouldn't be much of a difference and the 357sig barrel is just a waste of money..i guess it isn't but then again I don't think I need a bullet that'll penetrate as much as the 357sig would..but its still a cool option to have

[@wemcal]

Great video.... the 40 165 grain would have been better than the 180 grain... neither would have out penetrated the .357 sig

[@cogunlover5550]

Impressive

[@billyjack6658]

Great video. You could probably end the whole debate and and use the underwood extreme penetrator in 357 sig. 9 mm 40 caliber in 10 mm that was settled all arguments. And while you’re at it you could try the double tap 357 sig. in the 147 gr full metal jacket flat nose . I think that would be a task that everyone would want to see. Also to keep it uniform you can probably just do multiple sheets of plywood. Just a thought. Anyway great video you’re doing a great job. B

[@yosefmartinez9318]

you should a make a competition between 357 sig and 7.62 ×25mm tokarev due than 7.62 has more penetration than 40 s&w maybe 357 sig will find her counterpart

[@Mana_Cryptid]

I wasn't expecting this video to end with black metal lmao GG

[@jamesfrancis9725]

I love the .357 sig. But here's the thing. When you are comparing 125 gr to 180 gr of course there is going to be a difference and a huge one at that. For the .40 that is at the very top of the weight for bullets. Not sure what is at the top for the. 357 sig but the. 40 becomes ALOT closer to the .357 sig and a much better comparison when a lighter bullet is used.

[@ThePenetrationChannel]

James Francis the 147gr. Is pretty much as heavy as the 357 sig goes. But heres my issue, if I were to use a 140gr projectile in the 40, why should I use the heaviest bullet in 357? Should I not also decrease the weight for the 357? 125gr is middle of the road. There are heavier bullets for the 40 such as the 200 gr. So. I went with the 180. You can check out my underwood ammo comparison where I test a 140gr 40 s&w.

[@coreyfaith9745]

[@crowmagg1]

try a lighter 40 and heavy er 357 (if possible) when the 40 gets lighter it approaches the 357 sig in velocity

[@panzerkami2381]

"when the 40 gets lighter it approaches the 357 sig in velocity" Which won't change the kinetic energy one bit, and a lighter projectile with penetrate even less. So... no.

[@robertleo8006]

crowmagg1 agreed. Converting a 40 to 357sig, or versa visa, is in *most cases* just a matter of a barrel swap, seeing 135gr 40 s&w vs 125gr 357sig, and 155gr 40 vs 147gr 357 would really help determine if i need a barrel swap or just a lighter box of ammo! ... and also other guy who will probably be notified in this thread; kinetic energy is literally a product of mass and velocity, sooo......

[@billyjack6658]

Nice test. Have you tried using the double tap 147 grain hard cast flat nose in 357 sig.? Or the 125 grain Full metal jacket offering from underwood. Also to make it more uniform why don’t you just stack 10 to 12 pieces of half-inch plywood to make the test uniform actually you will probably need about 15. Just a thought. Great information

[@caseyterrence1606]

The 357 sig imo superior to the 9/40/45. My handgun caliber of choice is the 357 mag 125gr out of a 4in barrel. With semi autos obv being the preference for LE etc the 357 sig should be utilized by more departments esp highway men and any that will likely encounter barriers.

[@swaghauler8334]

The .357 SIG was far better in its original loadings. Remember that until the turn of the 21st Century, the standard loading of the .357 SIG was a 125-grain bullet traveling at 1450 to 1500 fps out of a 4" barrel. I guess the polymer framed guns (and shooters) couldn't stand the power of the original loading. I also remember when 1400 fps was a TYPICAL speed for 10mm Auto and virtually EVERY 230 grain .45 ACP round would ROUTINELY RUN 950 fps (not 820 to 880 fps) from a 5" barrel. The "wussification" of ammo in the 21st Century continues unabated.

[@troy3456789]

+swaghauler It is just how cheap and downgraded factory loads have gotten. They're not "wussified", they're "cheapified" and over millions of rounds, the manufacturer saves a lot of powder, thus money, thus maximizing profit. DoubleTap, Underwood and Buffalo Bore offer quality controlled standardized factory loads that are considered "premium" by today's standards, but were considered standard ammo performance/ballistics at the time the firearms were designed.

[@troy3456789]

+Steve Johnson 357 magnum and 357 sig are not similar on paper. 357 magnum outperforms it by 27% more energy. 357 magnum 158gr JHP Buffalo Bore= 1,475 ft/s & 763 ft·lbf energy. 357 Sig 125 gr Underwood TMJ = 1,450 ft/s & 583 ft·lbf energy.

[@markdavidson1049]

I prefer something heavier that moves a little slower but is also more cost-effective. .40

How far away from the target were you? I have never heard of a projectile breaking up before impact. If you were extremely close, maybe it was some unburned powder stippling the paper.

thank you I have a S&W in 40 SW an have been thinking of setting it up to run 357 sig often the bad guys will start crap then drive away I put first though the motor the crap stops here my question is will the 45 colt 250 gr. fmj. at 950 fps' do that job an can the 357 sig stop a running car motor in a pinch ???

The 40 had a 180 Grain slug. The 357 had a 125 grain slug. The difference in weight would vary the velocity. Thus, penetration is different. I laugh when these 357 Sig fanboys tout their Sig as if it was all more powerful than the 40, when they are using a dud load for the 40 and a hot load for the Sig. It's like comparing two crossbows. One is shooting arrows made of Balsa wood, while the other using using lightweight graphite arrows.

Nice test. Thank you. That made it clear. 1) Did you use the same kind of gun and same length barrel? 2) did the kick feel the same. They sounded the same.

both guns were M&Ps. both have 4.25" barrels. the recoil is similar in both calibers. the 357 has a louder blast even though it doesn't sound like it in the video. Thanks for watching!

so... through the bad guy then through a car door then through the kid setting in the car then through the other kid setting next to him... dont get me wrong, i am a huge fan of the 357 sig and i personally carry it often. but more than anything i hope that this video reminds people that as gun owners, we are responsible for every round that comes out of our guns. NO EXCEPTIONS!

philip mullins this video was to showcase the "penetration" capabilities of these two calibers. hence the use of fmj ammo. Hopefully if ANYONE carries a firearm for self defense, they will be carrying self defense ammo. Hollowpoint ammunition performs very similar to each other between carry calibers due to being designed to perform at a specific standard. If anyone carries fmj ammo for self defense, they greatly increase the chance of overpenetration. If one is responsible enough to carry a firearm, then hopefully they understand this risk.

i appreciate the reply. and i also appreciate the video. yall did a very good job of a real world, easy to understand comparison of the impressive penetration capabilities of both rounds. and i dont bother to reply to crappy videos. i was just offering my perspective on what these results could reveal. some people dont always think that sort of thing through. ammo prices, availability, extra mags, etc... not a complaint or passing any judgement on your vid. just adding food for thought for someone who might be watching this vid trying to decide on a caliber of weapon to buy for self defense. maybe their first handgun?

[@ThePenetrationChannel]

philip mullins no worries....thanks for the feedback. I welcome all perspectives.

[@marksmith351]

Stats show that cops miss around 2/3 of their shot so over penetration is not what many make it out to be.

very cool!
