10mm vs .40 S&W

[The_Shadow]

For me it’s the best of both worlds...10mm pistols and 40S&W conversion barrels! Why you might ask, 40S&W brass is free or cheap and plentiful, I cast my own bullets so a little time and powder & primers I up and shooting 40S&W from my 10mm pistols with the barrel swap. It builds proficiency and the same sight picture while practicing with the 40's. But with woods carry or street carry its 10mm with full throttled loadings! Oh, I can do the 357Sig or 9x25 Dillon also!

But this is America you are "FREE"(atleast for the time being) to do your own thing!

Enjoy and best regards!

Hey Shadow looks like you joined up just for this one.

[NordicG3K]

I prefer the 10 because of its versatility. It can do anything the .40 S&W can do and more. Besides, it's just plain cool!

[The_Shadow]

Kind of, I had been in and out of this forum looking from time to time, but never signed up. The 10mm pistols are a favorite of mine since 1990 with the first which was the S&W 1006. It sports extra Bar-Sto "Match Grade" 40S&W and 9x25 Dillon conversion barrels to play around with in addition to the 10mm.

The poll sort of sparked the intrest to sign up!

[liberty1]

Oh man I love all of those.

It would take a Military contracts or large LEO contracts for the current manufactures to produce a quantity guns for 10mm platform. Glock sells to other militay and LEO in other countries. Other than that they will be feeding the enthusiast passion.

The 10mm ammo watered down (to 40S&W) spec. is a definite problem. Also ever increasing attempts by manufactures’ to wring out as much power out of the 40S&W to achieve higher ballistics to the point of brass stretching and bulging doesn't help to shift platforms. Just look at the Redding "Push Thru Die" to squeeze the brass back for reuse, IMHO it think this will invite disaster if these are loaded to high pressure potentials.

The 10mm loaded to its potential(not over) is what it is, superior to 40S&W and 45ACP. If people actually measured the velocity that they get with the ammo they used in there guns, they would have a better understanding of what we are speaking of.

What has this led to? Bullets of weaker construction so they would perform in the weaker platforms, so the 10mm are being subjected to bullets not optimized for the caliber anymore. The bullet makers using plated bullets are flooding the market with cheap bullets of lesser quality(except for maybe Gold Dot® these are thicker plated and bonded) for the potential of 10mm velocities.

So what does it boil down to Cases, 10mm (0.992"/25.2mm) vs. 40S&W (0.850"/21.59mm) are 0.142"/3.61mm different in length and Cartridge Over All Length, different in length of 10mm (1.250") vs. 40S&W (1.125") 1/8" or 0.125" an the most significant feature Pressure 10mm (SAAMI 37,500psi) vs. 40S&W (SAAMI 35,000psi) difference of 2,500psi which is substantial in performance.

FBI wasted good money finding out that the 10mm was all that it could be, only to try and reinvent the wheel!

The 1016 would have been a 3.5" Barrels version of the 10** series pistol Traditional Double Action but Double Action Only due to the bobbed hammer but the decocker like that of the 1006 or 1066.

They made one in 45ACP S&W 4516 http://www.kitsune.addr.com/Firearms...ls/SW_4516.htm

Possible 3.50" model numbers based on the original lettering designations...
xx0x = full length barrel TDA
xx1x = compact barrel TDA
xx2x = full length barrel Frame Decocker
xx3x = compact barrel Frame Decocker
xx4x = full length barrel DAO
xx5x = compact barrel DAO
xx6x = mid size barrel TDA
xx7x = mid size barrel Frame Decocker
xx8x = mid size barrel DAO
xx9x = Special Order

xxx0 = Scandium frame

1016...like the 1006/1066 TDA
1036...like the 1026/1076 Frame Decocker
1056...like the 1046/1068 DAO
1096...special order

1000... = Scandium frame

OH Well!

I chose a .40 (G27) for CC because of the weight of the overall firearm when loaded and quantity of rounds.
Try this logic test - have someone shoot you with both and see which hurts more. then let us know.

[10mm, singing to .40 S&W] "Everything you can do I can do better..."



The 10mm does have a little more recoil and noticeably more snap than a 9mm, or a .45. Comparing apples to oranges, my G20 with full power Double Tap 180 grainers is still much more comfortable than a SIG Pro .40, which is my only experience with the .40. I fired one magazine through my friends SIG and went back to shooting my G20. I will say I have a P220 .45 that is much more comfortable to shoot than my G20. But I don't necessarily believe for a second that the 10mm has more snap than the .40. The recoil isn't bad. It isn't painful. It doesn't abuse you. I've seen a 16-year old girl handle my G20 with full power ammunition easily. It means you probably won't get the split times with the 10mm that you get with the 9mm. If that is all that matters to you, look elsewhere. I think there is as much folly in thinking split times is all that matters as there is thinking muzzle energy is all that matters.

The 10mm Auto may not be a grenade launcher or RPG, but it is a decent amount of firepower for an autoloader. It is ballistically very similar to a full power .357 Magnum. Nobody is surprised when they touch off a .357 Magnum and find it has more muzzle flip than their favorite 9mm. That's because everyone understands what the .357 is and the risks and rewards that are involved. Think of the 10mm as a .357 Magnum in an autoloader. Then you won't expect .1 sec split times and won't be disappointed when you don't get them...

[gun nut]

I'll stick with the 40 s&w.

10mm is great but, expensive. I would take .40

[gandog56]

Why choose? I have BOTH!

[Nite Ryder]

I voted for the 10 MM. It can do everything that a 40 S&W can do, and do it better. I have a 10 MM in a Ruger Blackhawk, S&W 610 revolver, Glock 20, and Springfield Target Omega. The Springfield is ported and I can do better with it during rapid fire than the Glock or 610. I reload for several pistol cartridges, 10 MM being one of them, so ammo will not be a problem until I can no longer buy primers. If a person shoots a lot, I suspect they can handle at 10 MM as well as a 40 S&W. For a casual shooter the 40 S&W might be a better choice. I intend getting a set of Crimson Trace grips for my Glock, and possible a ported barrel. I do like shooting the 10 MM, my shooting buddy hates anything that makes too much noise and thinks the 10 MM is totally worthless. But he doesn't spend money on anything that isn't an actual need. Myself, I know the difference between need and want...

[got_the_itch]

The 10mm is a bad mofo. But the price! I don't have a 10 but my little brother does. It's fun to shoot, but he's a lawyer. So he can afford to shoot it. LOL My .40 with the correct ammo suits me fine. And I feel it's within my comfort zone.

Cheers,

I own both, a Glock 20C, and a FN-40, The Glock is what I carry in the woods, the 40 is usually in my pick-up or Rhino. If you are not afraid of a little recoil, and can find the right ammo (or any ammo these days) I would go with the 10 if I had to choose just one. I would not want to be on the receiving end of either

[LoneStarWings]

Had a chance to test my .40 HST's on some milk jugs, 2 on the left are 180gr, two on the right are 165 gr. The 180's penetrated two milk jugs filled with water, put a hole in the back of a 3rd but came to rest in the bottom of that 3rd jug while expanding to .83". The 165's penetrated 4 jugs and came to rest in the 4th, and expanded to .70". Wish they made an HST in 10mm (and .357mag for that matter). The milk jugs were each 6" deep.

4.25" barrel, at 7 yards. The first milk jug got shredded in each case, and the cap had about 3 seconds of hang time before falling back to earth. I'm pretty confident that these would get the job done on a bad guy. 1st round under a nickel for reference.

[Jason607]

The 10mm gives you both mass and velosity, while with the .40S&W you have to choose one or compromise. A 10mm is like having you cake and eating it too.

[gandog56]

It's a tossup which gun I own is more accurate. My Dan Wesson Razorback 10mm, or my SIG P229 with its 40S&W and 357 SIG Barrels.

Like I said, lucky enough to own BOTH!

[Socrates3000]

Why not go for the round that is cheaper and more widely available.

[jgcoastie]

Why not go for the round that is cheaper and more widely available.

Absolutely! Let's do away with everything except .22lr. It's cheaper and more widely available than anything else.

Simply because the 10mm is more versatile than any other semi-auto cartridge. Period. Those who own them know, those who don't can only wonder, speculate, and poor-mouth the 10mm. All because they don't understand the true value of (arguably) one of the best handgun rounds available today.

Pros
-Bullet weights equal to the .45acp (230gr available)
-Velocity greater than a 9mm
-More powerful than a .357mag
-Can be down-loaded to a light .40s&w

Cons
-Practice ammo is typically more expensive than others (though comparable to .45acp practice ammo right now) Premium self-defense ammo is going to run about $.85-$1.00 per round anyway, so that's not a huge concern.
-Ammo is not as widely available as others
-Grip size is slightly larger than it's .40s&w counterparts
-Felt recoil is greater than .40s&w, but all else being equal, comparable to .45acp felt recoil

So basically, if you're Ted Nugent rich or reload (which negates the ammo price/availability) and you have larger hands (which negates the grip size) and can tolerate .45acp-type recoil, then the cons are not a huge factor.

Long live the mighty 10!

[Dragon55]

.40 I have no use for the 10mm

[ReNtaPiG]

All this talk of the 10mm being so comparable to the .45acp...then why not just get a .45acp??

Sounds to me like you could benefit from a nice 1911

[srt 10 jimbo]

I have a .40 If I wanted to go bigger, I'd get a .45

[happy1]

I've got both a Colt Delta-Elite 10MM and a Star FireStar .40S&W The 10mm by far my favorite.
