9mm vs. 10mm


March 8, 2007, 08:35 AM
I don't know if this thread/ caliber war has ever been done, but hey what the heck,.. why not. Personally I think the Glock 20 completely trumps the Glock 17, but that's just one example.

I went with 10mm my personel choice,but I guess it depends on what you intend to do with it.

March 8, 2007, 11:00 AM
I own both and like each of them.

But I carry a G29 every day.

March 8, 2007, 03:39 PM
10mm is THE autopistol round.

March 8, 2007, 03:41 PM
Voted for 9mm just to stir the pot. Aside from hunting I can do anything the ten will do with a 9, probably faster and certainly cheaper too.

March 8, 2007, 03:49 PM
I actually was going to vote 9mm, as it is my favorite. But I voted 10mm. My reasoning:
You can load 10mm in everything from mild low-recoiling personal defense loads, all the way up to bone-smashing hunting loads.

For most people 9mm is a better choice, but for the expert/handloader 10mm is much more versatile.

March 8, 2007, 04:57 PM
Which one is the all-around better round?
Because of its lower recoil, wider and more readily available ammo selection, and wider and more readily available section of weapons chambered for it the 9mm would be my choice for best defensive round.

However, you asked which is the better all-around cartridge. In terms of versatility and all-around capability the 10mm wins out; the reasons have already been explained.

I was at the range today shooting my CZ75B, which is 9mm.

I'm having problems with discs in my spine that are disintegrating and even the 9mm from a fairly heavy pistol like the CZ75B left me in some pain.
I can just imagine how much more pain I would have, were I shooting a 10mm-:barf:

I voted 9mm.

9mm all the way, cheap to shoot, low recoil, lots of good self def ammo
10mm not really cheap, ammo is scarce around here, good snap with it

10mm. Love the nine, don't get me wrong, but the 10 is probably the best all-around handgun cartridge for autos. And not being much into revolvers, that says best all-around for me.:cool:

March 8, 2007, 09:44 PM
I like both but if you factor in ammo cost & availability, 9mm wins :cool:

March 8, 2007, 09:47 PM
Personally, to me this is like asking:

Which is better:

1. A .50MBG AP round
2. A 40mm grenade

Both are powerful, but both are for somewhat specific uses.

9mm is a good all-around round.... and 10mm is certainly more powerful... but there is a huge difference in power between the two.

a better comparison is 9mm vs .40 (10mm lite) or the standard 9mm vs .45

March 8, 2007, 10:57 PM
If I reloaded I'd probably give a lot more consideration to the 10mm, however, since I don't I'm going to stick with the 9mm. For what I use handguns for the 9mm works just fine.

March 9, 2007, 08:15 AM
I like both but if you factor in ammo cost & availability, 9mm wins

Ah, but I DO reload, so 10 mm wins.

March 9, 2007, 08:37 AM
Easy question, complicated answer. For versitility the 10 wins hands down, mild to wild, depending on the load. For number of platforms available in all different sizes and ammo availability, the nine is the winner.
Uh------------what was the question again?

March 9, 2007, 09:32 AM
Father, have I sinned by wanting to buy a 10mm auto just so that when some homie stumbles on us talking about guns at the store and mentions "Yo, holmes, I got a nine, foo" I can say "Yes, but I have a ten?"

March 9, 2007, 09:38 AM
I prefer 9mm because I am a CZ 75/85 and P01 fan.

Also, I like that availability factor.

March 9, 2007, 10:08 AM
You might want to compare 38 special to 41 magnum. These and the 9mm and 10mm are two very different rounds with different skill levels involved.

This is one of the reasons the M9 was adopted It's a better all around pistol/caliber for most members of the armed forces.

March 9, 2007, 04:41 PM
FBI had a problem with 10mms going THROUGH people. Gimme good hollows and I'll take the 9mm for defense... against people. If I'm being robbed by a black bear I'd reconsider...


March 9, 2007, 04:44 PM
Giving proper ammo and good shot placement, either will do the job of personal defense.

But in my personal opinion, the better all around cartridge due to ammo cost, availability, and lower recoil is the 9mm.

March 9, 2007, 06:51 PM
Obviously power wise the 10mm blows away the 9mm, but the 9mm really shines when it comes to small CCW type weapons(ie: Kahr PM9).

Loaded with high quality hollow point loads, I'm pretty sure that a bad guy wouldn't know the difference though.

March 11, 2007, 02:57 PM
IMO, 10mm has more options. It can be loaded to low 40S&W minor power comp level to hotter level for hunting.

FBI had problems with 10mm only because their agents couldn't qualify with it(I guess it was little to much for them). That's why they had to ease off to the lite load which gave birth to the 40S&W.

March 11, 2007, 03:03 PM
10MM beats 9MM anyday.

March 11, 2007, 03:39 PM
You're comparing apples and oranges. Each has its advantages. The 9 can be built in lighter, smaller pistols more suited to all day concealed carry or duty use, having low enough recoil for quick follow-up shots, and the added advantage of cheap ammo. The 10 shines where a larger and heavier pistol is not an objection, like for rural open carry or hunting.

I shoot mostly .45, but would love to have a nice 9mm AND a good accurate 10. And I would still shoot my .45 since neither of these guns could replace it for my purposes.

March 11, 2007, 03:43 PM
9mm vs 10mm?

That's like asking ".380 acp vs. .357 magnum"

March 11, 2007, 05:12 PM
Man, that's tough. "All around" tells me it needs to be available in CCW size guns and the 9 has that covered. I don't carry big, heavy guns like 1911s or EEA Witnesses much. I have a Ruger P90, but it mostly sits in a case while either my .38 snub or my pocket 9, a Kel Tec P11, does day to day pocket duty. Now, outdoors, hunting, the 10 is the answer to the question if you like autos and I don't, not much, for outdoor use. I prefer my Blackhawks and my Contender.

So, I voted 9mm, but all us revolver guys know this poll is a complete joke. Neither competes with the .38/.357 for "all around". :neener:

March 11, 2007, 10:15 PM
its a dead tie, 66-66!

March 11, 2007, 10:33 PM
I went for the 10mm as it can do whatever you want it to. Load it light for plinking or hot for deer hunting if you wish. 9mm is fine but if I had to choose only 1 it would be the 10mm.

March 12, 2007, 02:09 AM
9mm... Its what I have and carry... glad I bought a whack of it before the prices started heading up

March 12, 2007, 02:13 AM

This is compairing apples to oranges. 10mm is the better deffence/hunting round if you can handle the recoil, 9mm is much more economical to shoot. nuff said.


March 12, 2007, 02:22 AM
The 10mm is the 30-06 of the handgun world, the only thing missing is the popularity.

March 12, 2007, 04:53 PM
10mm wins hands down!! Whether you reload or not (and I do) there are many commercial loadings available for this caliber ranging from 135grn up to 200grn. I have two Smiths a 1006 and a 1076 and firing any load from these guns is no worse than a 9mm as these heavy suckers just soak up the recoil. I have been a 1911 man for over thirty years and just recently switched to the 10mm as where I live there have been quite a few sightings of cougars/Mountain lions and I just can't depend on the 45 to make a clean kill, with the 10mm, no worry!! Load up either with Double Tap and either 2 legged or 4, I feel good to go!

FBI had a problem with 10mms going THROUGH people.

That statement..... was freekin' entertaining far beyond imagination.

March 14, 2007, 10:57 PM
I thought it was just that the average FBI agent couldn't handle the recoil of a full-power 10mm, which is why they starting under-loading them.... and then S&W realized that there was no need for the extra case space one day and came up with the .40SW based on the loadings of the 10mm used by the FBI...

or am I wrong?

March 14, 2007, 11:22 PM
Isn't this like asking "What's better, a Honda Civic or a BMW sports sedan?"

The 10mm is way more powerful, but ammo is way more expensive.

March 15, 2007, 12:04 AM
I won't be taking my 9mm deer hunting.

March 15, 2007, 10:33 AM
I won't be taking my 9mm deer hunting.
If you're talking about hunting rounds, the 10mm should be left at home too.

Bring your 44mag.

March 15, 2007, 11:52 AM
180gr XTP at 1400+ FPS (6" barrel).

I don't know what kind of deer you shoot at, but that's plenty.

March 15, 2007, 01:29 PM
I voted 10mm. I reload, and I carry a G29.

Ask yourself this question:

If you had a bad guy charging at you and had a 9mm and a 10mm on the table in front of you, and could only pick one, which would it be?

9mm vs. 10mm

Whichever one you shoot better.

March 15, 2007, 02:57 PM
9mm -- in +P defensive load format, plenty lethal for humans (or, probably more proper to say it does not suck any more or less than every other pistol cartridge out there, since none get the job done very reliably), and quicker back on target for follow up shots.

That's pretty much my definition of ideal in a defensive handgun -- adequate penetration/power to kill someone if I do my job and put the bullets somewhere important, and as absolutely little recoil as possible so I can follow up with additional rounds to ensure the job gets done. I wouldn't go lighter than 9mm (and like 45 ACP) but don't see the point for 10mm if the concern is two legged predators.

March 15, 2007, 03:20 PM
While they truly are in different leagues, the 10mm is far more versatile. It is suitable for anything from match shooting to personal defense to medium game hunting. With the ability to go from the low end loads that are similar in kinetic energy to a 9x19, all the way to top level loads that nip at the heels of the .41 magnum, and the ability to use bullets from 135 to 220 grains, it is about as flexible as an autolading pistol cartridge can possibly be.

That said, for deep concealment, 10mm pistols just don't get that small. The Kahr PM9/K-T PF9 are much smaller and roughly 1/3 the weight of the only compact 10mm's; the Tanfoglio Witness Compact and the Glock 29.

March 15, 2007, 04:00 PM
The 10mm is definately the more capable cartridge but it's a commercial midget next to the 9mm and other popular service rounds, so picked the ubiquitous "euro pellet" over what's basically a semi wildcat.
