10mm v .357 Magnum


June 21, 2007, 11:19 AM
I am considering to buy at new handgun, which is more powerfull than 9mm. The choices I have in front of me are 10mm and .357 Magnum. But not sure which one is better in terms of power and self defense use. Right now I carry 9mm pistols and .45s, and wanted to add more power to the collection.

Your opinons are more than welcome.

The bigger frontal area of the 10 would seem to give it the edge. This is with the assumption of a decently brisk load: say, Double Tap's 135-grain JHP at their advertised 1600 fps, which appears to be a pretty close match to the proven fight-stopper, the 125-g SJHP .357 Magnum.
You can always mess up the comparison by changing loads, but this particular one would seem -- at least on paper -- to be very effective.

Which make do you recomend in 10mm, other than Glock.
I have alse heard that FBI adopted 10mm and later droped it. Why? I dont know. Any thoughts on that (anybody)?

June 21, 2007, 11:55 AM
They dropped it because of excesive recoil using full power loads. The FBI load (a lower power 10mm) is what became the 40 S&W. I believe that the frame size also played a role in the development/adoption of the 40 S&W to accomadate agents with smaller hands.

I'd have to answer your question with another revolver or auto,if auto 10mm if revolver 10mm if you can afford it if not 357

June 21, 2007, 01:03 PM
I'd say both 10mm and .357 are great rounds with a lot of versatility. 10mm unfortunately is not nearly as common, available or widely used as .357mag.

That said, the question really is: do you like revolvers or automatics?

June 21, 2007, 01:11 PM
Your 10mm is about equal to a 41mag. Ammo is kinda of high, but worth it. I had a Dan Wesson Pointman and should have never let it go. The only other pistol I have liked better is my Les Baer PII. Check out the DW

the question really is: do you like revolvers or automatics?

I tell you what, I would love a 10mm, but it's not the most popular of rounds, if it was as popular as 9/40/45 I probably wouldn't own a .45 at all.
Oh, and I love my .357.

June 21, 2007, 01:21 PM
I own both a Glock 29 and a Dan Wesson Model 15 .357 Mag. Both are hellaciously powerful rounds. I reload all my bullets because of the price.

I would have settled for a .357 Mag autoloader if they made them, but the 10 is just a kick ass round. I'm a large framed guy, so the recoil from either is manageable. But the DW is just too damned bulky with it's 6" barrel to be concealed.

I'm not a fan of the .357 Sig, however.

June 21, 2007, 01:39 PM
The issue is revolver or semi-auto, no? Which do you prefer?

June 21, 2007, 01:55 PM
The 10mm is available in the 1911 platform, while, with the exception of the uber-cool Coonan guns, the .357 Magnum is not. So settleth the argument...


June 21, 2007, 01:56 PM
I really like 10mm, but given what happens to the gun after you shoot and the police pick it up (ruined by evidence handling), .357 might be less of a heartbreaker.

Both are damn fine for defense.

10mm firearms - I hear surprisingly good things about the cz clone witness pistols in in 10mm. Steel frames and 15 round capacity is a nice mix.

If you look around you might still be able to find a smith and wesson revolver in 10mm, which is also a dang fine looker.

.357 magnum has a lot of excellent choices in terms of low budget quality revolvers. There has been the rare auto for the round, but they are bulky and obscure.

if you ever decide to expand your range into handgun + carbine, .357 has a few levergun choices which adds to the appeal of the round.

June 21, 2007, 01:57 PM
Tough, tough choice but I voted for 10mm.

I've been sold on the 10mm's versatility for some time, having owned a Colt Delta Elite. It's good with .40 S&W-equivalent loads as well as stronger loads.
However, the .357 Magnum is also a sentimental favorite but, truth told, I'd rather have the 10mm. The reason: If the 10mm can do everything that the .357 Magnum can do, it does so in a more efficient package, so that's why it got my vote.

June 21, 2007, 02:02 PM
The 10mm can be found chambered in new autos made by Glock, Witness, Kimber, and Dan Wesson. The Witness is a CZ clone, the Kimber and DW are 1911s.

Used, it's available in autos from S&W (the 10xx series-1076 was what the FBI used) and Colt (the Delta Elite). There are also some less common ones like the Bren 10 floating around. S&W also made a revolver, the 610, in 10mm.

Pretty much every company that makes or has ever made revolvers made at least one model in .357 Magnum.

June 21, 2007, 02:18 PM
Go for the Ten and don't look back. The 200gr hollow point at over 1200 fps is midway between the 357 and the 41 magnum. Sixteen rounds in a very nice comfortable pistol (the Witness full size all steel) is a joy to have on your hip and much fun at the range. Bullets are available in weights from 135 to 220 grains and muzzle energy ranges up to over seven hundred foot pounds. My Witness is very accurate out to a hundred yards without holding six feet over the target. The .40 cal 200gr bullet has a very good ballistic coefficient and doesn't shed velocity like similar weight .45s. For summer self defense against humans the 135 gr at 1600 fps is good as stated above but don't trust it in the winter in cold climates as it can literally come apart penetrating heavy clothing whereas the 200 gr hollow point or solid just keeps on going like 18" in gelatin.

Here's a link to a formerly stickied thread containing links to most, if not all, THR threads on the 10mm; http://www.thehighroad.org/showthread.php?t=206247&highlight=10mm+threads. Plenty of reading there.

Should've said "can do everything...plus maybe a little more." But anyway...

And thanks, OneShot! I've succeeded in talking myself into a future 10mm! :D

June 21, 2007, 04:48 PM
Ya'll have warmed my heart. As an owner of a 10, I would pick it also. I have owned 357's and have liked them very much but I lean toward autoloaders. I personally carry the Witness full size steel frame 10mm in an IWB holster.

June 21, 2007, 06:12 PM
You guys check out randgfirearms.com he has a engraved Delta Elite. Sweeeeeeeeet

June 21, 2007, 06:25 PM
I like 'em both, but the 10mm is my favorite cartridge period.

My Glock 20 with 16 rounds of 180gr doubletap ammo? Yeah, I'm good. :)

I have both a GP100 .357 Mag, and a Glock 20 10mm. I like both of them very much, and don't plan on parting with either one. I give a slight edge to the 10mm though, it's just too neat to be without. If companies like DoubleTap stay in business, then my Glock 20 will stay with me forever :D!!! Although .357 mag is much easier to find, when you find true " full power " 10mm ammo it makes the search all that more rewarding ;).

P.S - stay away from .357 sig, you will be better served by a plain vanilla 9mm. Don't let the flash and blast fool you!

June 21, 2007, 07:20 PM
I'm voting for the 10mm, mainly since your listed prior experience is in autoloaders.

June 21, 2007, 07:58 PM
While there is absolutely nothing wrong with the .357 Magnum, I also voted for the 10mm. Absolutely LOVE this cartridge. I like its power, I like its performance, I like the platforms it is/was offered in, and there's something cool about owning a caliber that's off the beaten path.

If you opt for the 10mm, I'd stick to loads in the 155-gr. to 180-gr. range for SD purposes. To me, the 135-gr. weight is just too light and the 10 hits its stride with the heavier bullets.

June 21, 2007, 08:20 PM
Actually, now that I think about it, you should do like I do and go for both

June 21, 2007, 08:34 PM
the computer agrees they're both great notice the poll = 102%

Sure enough!


June 21, 2007, 10:43 PM
I got them both! A 10mm Dan Wesson Razorback and a Taurus 66 6" .357 revolver. I can load up the .357's a little hotter, but love the feel of a 10mm 1911 in my hand. Plus its 8 10mm rounds (with a couple of 10 round mags also) to the Taurus's 6.

June 21, 2007, 10:54 PM
While IMO the 10mm is a more powerful round and I like it a lot better then the 357mag and 15rnds of 10mm beats 6 rnds of 357mag.

It is my understanding in that in real life nothing comes close to the 357mags one shot stop record. So that being the case I had to vote for the .357mag.

June 22, 2007, 12:15 AM

Carry a 10mm auto as prime.
Carry a .375 as backup/deep conceal.

They're really 2 very different animals.

June 22, 2007, 01:07 AM
I'm a semiauto guy so I voted for the 10MM which is my woods gun . Packs a bigger whallop than my 357 Mag and ammo isn't that hard to find at all .

Damn, I don't wanna know where you conceal a .375 handgun! :D

June 22, 2007, 02:07 AM
This question is not about the cartridge difference - they are pretty much in the same ballpark and may both be the best self-defense cartridges around. The question is whether you want a revolver or autoloader. Pick the gun.

June 22, 2007, 02:56 AM
It's just my opinion, but I think its a no-brainer...10mm all the way. Like already mentioned, they are both versatile loads, but cmon..a 10mm projectile traveling at 1400-1600fps, or a 9mm projectile traveling at 1400-1600? I'll take the 10mm...16 10mm shots from a Glock is no joke either. 6 from a revolver or 16 shots from an auto?

Maybe I'm biased towards autos, but I still think if you are after raw power/numbers, a 10mm Glock would be your best bet.

June 22, 2007, 03:00 PM
by caliber I like 357 better. but it is a revolver bullet so the question is do you like revolvers?

August 19, 2007, 12:34 AM

August 19, 2007, 01:54 AM
10mm if you like semi-autos, .357 if you prefer revolvers. Or something like that. With a glock 20 or 29, you still get more rounds before reloading. With the .357, you get a platform with more versatile barrel length. Love both, but haven't seen the .357 do anything that the 10mm couldn't.

However, here's the kicker: .357 is much more popular and accessible...and you can shoot .38 in the same weapon for less money. With 10mm, you are stuck with the price, period. Your only way out is to have a glock or Witness and get yourself a .40 barrel so you can shoot the cheaper ammo. Then again, that takes away from the purpose of having the 10 mm in the first place. For longevity, go with the .357, it will always be around. The 10 should be around too, but weapon platforms are fewer and it may actually fade more into the background.

Of course, you could always get both. However, if I had to pick only one or the other: .357, for all the reasons stated above. You can always hand down a good revolver from generation to generation, too.

August 19, 2007, 02:28 AM
The FBI stopped issuing the 10mm because it was hard to control and follow up shots were difficult. Why would you want to make things hard for yourself if a SD situation arises? I'm not knocking the 10mm at all because it is a very powerful round and I am a very big fan of the .357 Magnum too. I see many here don't like revolvers and if you agree why not buy a pistol that's chambered in .357 SIG? As you know the .357 SIG was developed to mimic the .357 Magnum in a semi-auto pistol. It's just another option that might make your decision a little easier. (or maybe a little harder LOL)

August 19, 2007, 02:31 AM
First of all, just because a 10mm has higher ballistics doesn't mean it will perform better than the .357. And, while many on this thread clearly like the 10mm (and .357), there are many more who post regularly on this website who wouldn't go near them due to their substantial recoil and blast.
Whichever you choose, be sure that you can shoot them as well as you can the lesser power calibers you are shooting now or you are defeating the purpose.

August 19, 2007, 04:25 PM
L-Frame brings up a good point. If you go with the 10mm are you prepared to buy or reload enough ammo to attain a level of proficeincy with it that will match the 9mm's you're replacing?

August 19, 2007, 07:50 PM
IMO, whether you choose 10mm or .357 does'nt make much difference; they're both great rounds !; but one forum member's end quote says it best...

" shot placement is King, penetration is Queen, everything else is just angels dancing on the heads of pins"

.357 magnum
August 19, 2007, 08:47 PM
More shots with the 10mm. I have had a lot of experience with the .357 Mag. I switched to semi-auto's over a year ago, never looked back. In fact I would recommend the .45:evil:- less kick, easier to place your shot's-more ammo choices:cool:. A lot of the .45- 230gr HP's are real stoppers! The Federal HST and Hydra-Shok, Winchester Ranger's and The SXT. Remington Golden Sabers, Speer Gold Dot's.

The Best to you and Yours!


August 20, 2007, 04:21 AM
It would be stupid to REPLACE a 9mm with a 10mm.

The full power 10mm loads in a glock 20 or EAA Witness are NOT anymore "blast/roar/buck/whatever" than a full power .357 in a revolver. Trust me. I've owned and shot both extensively. The only thing soaking up any recoil in the revolver is weight. The action and low bore axis does it for you in the glock.

It doesn't matter if you can't shoot the dang gun worth anything. If you can't place the shots, don't even pick up the gun. If you can't handle recoil, please don't bother with either cartridge, 'cause you won't like either one. Both will penetrate and shoot accurately, time after time.....again, if YOU can. Don't worry about the cartridge or the gun. Both will perform quite nicely.

Better to be downright surgical with a Bersa Thunder .380 than keyboard commando with an HK USP .45 Elite.

August 20, 2007, 04:45 AM
I think the 10mm has the edge with slightly better ballistics and usually a higher capacity package. If ammo available is a concern for you though .357 is hands down the winner. If you don't reload 10mm can also be a killer.

As usual the stories of the 10mm recoil in this thread are greatly exaggerated.

August 20, 2007, 08:49 PM
10mm is a .357 ballistically speaking, just add a lot of rounds in an autoloading format. My Ruger GP-100 has significantly more recoil and blast (sideways as well as straight ahead) than my Glock 20. The Glock-20 doesn't feel any different than the .45acp to me. I have heard the buisness about the .45 being "a push" vs other rounds but I just didn't see it.

Whether you pick .45acp or GAP, .40, 357mag, 357sig, or 10mm, they will all have more recoil than the standard 9mm. This will increase follow up time. Move up to a 9mm+P or +P+ and the difference becomes less significant. When I hear most folks talk about 9mm vs caliber x split times, they are practicing with standard 9mm's and carry +Ps or +P+s.

It all depends on whether you believe FPE adds anything beyond penetration and expansion. Some would have you believe that beyond 125-147ish gr expansion (permanent crush injury) and 10-12" of penetration that the rest is wasted kinetic energy. This doesn't necessarily jive with why the .357mag was considered the metric SD round or the common sense that 300 FPE difference b/w the 9mm and 10mm or .357mag just "evaporates" into thin air.
