I have seen quite a few 10mm pistols for sale recently. Is there a major difference between the 9mm and 10mm?? What would be the advantage of 10mm?

mmm....are you being serious?? :) i own both and 10mm kicks butt!!! it might be too powerful for some people. do a google search on how powerful a 10mm is. don't take my word on this, but i read somewhere that a 10mm is about the same as .41 super.

BIG difference between 9 and 10mm.

The 9mm is certainly easier to find ammo for, and less expensive by far than most of what you will find in 10mm factory ammo.

The 10mm is a versatile cartridge, through handloading it can be mild like a
.40 S&W or nearly as hot as a .41 Magnum.

There are many more firearms available in 9mm vs. the 10mm.

The 9mm handgun typically has a muzzle energy of 350 to 400 foot pounds, while the 10mm has a muzzle energy of 550 to 600 foot pounds, depending on barrel length and load used.

9mm practice ammo costs $10 to $12 per 50, while 10mm practice ammo costs $20 to $25 per 50.

10 mm is more like 700-800 foot pounds

10mm is one of two cartridges in a semi auto handgun that broke the mold for the ballistic gelatin during testing. The other was .357 sig. 9mm pales in comaparison. If you have a ton of extra cash to spend and don't mind having more recoil 10mm is a good way to go, but if you have more limited funding and wish to shoot a lot more for less 9mm is the way to go.

About 1mm?? If you are new to shooting handguns, start with a 9mm that you can get a .22 conversion for. Learn the basics and shoot it a lot with the .22s. Become accostomed to the recoil of the 9mm. Get your skills developed on a less powerful and cheaper to shoot gun before moving up. Then go to a range that has a 10mm available to rent. Try it out to see if it is something that you would want to spend you money on.

The main difference: Money

The reason why you see 10mm pistols for sale: Money

For paper punching and SD, the 9mm is entirely suitable. The 10mmAuto can be significantly more powerful, but there are also 10mmLite loads comparable to .40S&W levels (.40S&W is nothing more than a shortened 10mmAuto with a small primer pocket). The 10mmAuto is an excellent cartridge but ammo is significantly more expensive than 9x19mm, .40S&W or .45ACP since it is not currently adopted/issued by a major LE department/agency. You REALLY need to reload, to be able to shoot the 10mm, even then the cases are more expensive. The 10mm can be loaded from .40S&W to mid-range .41Mag levels. You don't see many 10mm's in competitive shooting circles because it doesn't give a competitive advantage and the brass is expensive, when it's a lost brass match. Very versatile and a wonderful offensive carbine load.

as an example of energy in other rounds.

9mm = .38 spl +P
10mm = .41 Magnum

9mmepiphany:

.38 special +p only runs about 20,000cup
9mm runs at almost 40,000psi in standard form and over 40k in +p and +p+

Needless to say 9mm runs at much higher pressures than any .38 special cartridge. The .38 special even in +p+ comes nowhere near 9mm in any catergory including muzzle velocity, energy, and/or pressure.

The advantage of the 10mm would be increased penetration potential against barriers, and potentially game animals. If you want that kind of performance and want an autoloader that can serve multiple purposes, then 10mm may be a decent choice. It still isn't quite up to .41 magnum levels. .41 magnum can be loaded with much heavier bullets, and it also is usually loaded pretty mild from the factory, so comparing the hottest 10mm loads to mild .41 magnum loads is not accurate. It is probably a step up from .357 magnum though.

If you're talking about it's usefulness from purley a home defense perspective, then the 10mm is actually closer in terminal performance to the .40S&W. Most manufactures have not designed their modern hollowpoints for use in full house 10mm loads, thus their currently isn't a defense load that takes full advantage of its performance. And yes I know DT makes some hot loads for 10mm with HPs, however those bullets were designed for the .40s&w. Keep in mind those HPs are designed to expand to a point and then stop. They have an expansion limit, and when they reach a velocity higher than intended the petals just fold back without more expansion. Tests conducted by Dr. Gary Roberts show that while the DT loads in .40s&w did offer more pentration than identical weight factory loaded gold dot loads, they did not offer more expansion.

Modern 9mm HPs perform well, and if all you're looking for is a general HD/range caliber it will serve you well. If you're looking at something for potential run ins with larger animals then the 10mm has a significant advantage. Or if you already have guns chambered in other calibers then 10mm is a fun cartridge to shoot, so there's always the fun factor.

Definitely money is the issue. If I seriously had like infinite money to spend on ammo, plus watermelons and other various fruits to shoot at.. I'd shoot 10mm all day just to be able to really appreciate 10mm.

9mm is considered the more practical ammo. Easy to control, good price, and in another state - you get much more ammo per mag.

Some people want to pick on the 9mm always claiming "weak knock down power". But in reality, they have never seen anyone shot or knocked down, I have.

Trust me, 9mm will kill you dead, even the FMJ.

i believe you...that wasn't the point

the point was to give a relative comparsion between the .38Spl and the .41 Mag...was i incorrect?

10 mm is more like 700-800 foot pounds

I checked several ammunition websites and found the following muzzle energy figures for 10mm:

Federal AE 180 gr FMJ - 424 ft-lbs
Federal Hydrashok 180 gr HP - 424 ft-lbs
CCI Blazer 200 gr FMJ - 431 ft-lbs
Corbon 165 gr JHP - 573 ft-lbs
Winchester Silvertip 175 gr HP - 649 ft-lbs

I would contend that most commercial 10mm ammo is well below your range of 700 to 800 ft-lbs.

Most of the 10mm ammo loaded by the major manufacturer's is loaded to the original anemic FBI spec of 180gr@950fps, that's .40SW territory. The Win Silvertip is the last, close to original power loading for the 10mm, from a major manufacturer. The only ammo companies that are loading the 10mm to/near its original (Norma AB) specification are: Corbon, DoubleTap and BuffaloBore. They load ammo in the 200gr@1200fps, 180gr@1300fps range, 155gr@1500fps range.

10mm round has more kinetic energy @ 100 yds. than the 9 does @ the muzzle

180 grn in 10mm travels the same speed as 115 grn in 9mm
the recoil of the different rounds is also significant

I'm a 10MM proponent. I have nothing against the 9MM. It is a good round. But, the 10MM does everything the 9MM does but a lot better. It does take more practice and it is more expensive to shoot. I'm a reloader so I load my 10to suit my mood, practice time and fun time at the range. The recoil is completely managable and let's face it - more is more. The 10MM is alive and well with a great future.

I may hear a lot of disagreement on this, but, I believe the 10 is closer in ballistics to the .357 mag than the 41 mag. Please don't quote me inflated fps numbers. Just look at the reloading manuals, Corbon or Double Tap data. Now that being said, I've fine with true .357 ballistic statistics for my semi-auto. AND, no the .357 SIG is not strong enough to be in this comparison. It (10MM) is a proven manstopper, barrier penetration maker and very accurate round. Done...........

The caliber debate will never end. There will always be another newer, better, faster, heavier, more deadly round, and a bunch of people recommending it. When you ask most of them what they'd keep if they could only have 1 caliber for everything, plinking, competition, HD, SD, etc, they either say 9mm or .45 90% of the time.

When it comes down to it, you will be able to afford to shoot the 9mm much, much more, and both will kill somebody just as dead. So go with the 9mm if you're worried about humans. Who cares if you can drop somebody at 100yards, somebody 100yards is not a threat in the eyes of the law, so if you don find yourself shooting at somebody that far away, you'll soon find yourself in prison. All pistol rounds suck compared to rifle rounds, so if you're worried about hunting an animal at that kind of range, get a rifle. In an average home where an average gun-owner mite live, you'd be hard pressed to find a straight shot over 50 feet, at that range, both the 9mm and 10mm will require skill to hit the target, and both will likely drop the target in a single well placed shot, yet neither is likely to drop the target wih a poorly placed shot.

Just wait for the 11mm round, it's 1 more, and it will be the new "in" round.

Some people want to pick on the 9mm always claiming "weak knock down power". But in reality, they have never seen anyone shot or knocked down, I have.

Trust me, 9mm will kill you dead, even the FMJ.

Had that discussion the other day with a friend. He was giving me crap for keeping a 9mm loaded and ready as my HD gun, apparently anything smaller than .40cal is not lethal:rolleyes:

What does he shoot you may ask? A 6-shot .38 special with a 2" barrel of course, much better than having 10 rounds of 9mm and a 4" barrel to shoot it out of.

Good idea...I love my Glock 29. With G20 Magazines I can have 16 rounds of 10MM at hand. But one gun is never enough; get a Glock 19 as well for shooting 9mm.

The thing about the 10MM is it WILL zip thru car doors and windshields without hesitation. The perfect weapon for those "get home" adventures right after a 8.5 Quake shuts down the LA Basin. The perfect platform that stores in a locked briefcase in the trunk of your car.

With the drop in barrels you can shoot for less $ and have many options.

and no, a GLOCK doesn't have to be UGLY....:43:

I thought the 10mm didn't actually have a very good record of stopping power. At least I remember reading Ayoob saying that the documented shootings with 10mm were fairly disappointing. Worse than 40 cal and 9mm even.

Now that's funny... 9mm vs 10mm

Like saying bicycle vs Harley... :D

Seriously, I had a delta elite 10mm for 20+ years. I reloaded more ammo for it because back then it was
tough to find ammo period. Then the FBI wimped the ammo out for the girls and limp richards who couldn't handle the round or the large double action guns that it had to fit in.. more the real reason.. For those of you who love the SW40 you owe it to the 10mm. A little to long to fit in guns which fit gals and small handed men and a little to much thump to shoot effectively over and over without a lot of ammo time and training..

The 10mm is an offensive cartridge by design. IT shoots through stuff easily. Black talons back in the day were the best thing going
they at least tried to expand. Current HP bullets do expand better. If ayoob wrote negitive about the 10mm stopping power it was prob due to the fact that back then the bullets wouldn't expand and they were getting through and throughs and the bullet was not imparting all it's energy on target.

Like has been said you can load up the 10mm hot and get to but not surpass the 41magnum. I own and reload those too. Duh...
the cases on the 10mm for reloading is thick and you can get a number of reloads per case especially if you don't load em too hot.

One of the best 10mm pistols out there is a revolver by S&W with a longer barrel 4" or more.

9mm cheaper to shoot and not as much kinetic energy. half really... I'd rather not get shot with either.
If you plan on shooting the 10mm a lot you will have to reload or buy in bulk unless you are a rich man.
The 9mm no so much.

The 10mm in the glock is pretty reliable and the recoil is less than what I experienced in the 1911 format.
I believe the 10mm is not a great round for the 1911 gun.. The slide moves faster and the mags even with new springs have a job keeping up with the timing of the gun. This after 20+ years with the thing. it worked but it was never reliable. Perhaps the new 1911s are more reliable. My old Colt delta went back to Colt a few times...

The 10mm is as accurate as most pistol cartridges out there and I hunted with it out to 75 yards.
Its a flat shooting round. One you can count on in the right gun. I switched to the 41 magnum for this role much better and I wasn't looking for brass on the ground after shooting..

With the 10mm It is a handful to shoot multiple rounds quickly and stay on target. The 45 less so the 9mm like a kitten in comparison for quick shooting and staying center mass. For me the 10mm was one centerfire round that back then allowed me to do it all Self Def. Offense/hunting and target practice for fun.

I DID worry though about 10mm through and throughs and then the round going through sheet rock and hitting my family members. So I got rid of it and went with a Glock 19 which I knew would have better expanding ammo and less risk of getting punched through bad guys and sheet rock.

Do you need a 10mm nope.. the 9mm will do everthing you will need it to for Self Def against the two legged critters. Just shoot good ammo and your good to go.

the 10mm is fun and if that is what you are looking for.. there is no reason not to.. for Self Def again the 9mm is a great choice. Cheaper to shoot good ammo availability and well made ammo for SD. YOu will prob be able to become a better self defensive shooter with a 9mm because you will be able to shoot more because of cost. You will be able to stay on target and put more rounds out quicker than you would with the 10mm.. because the recoil impulse is less. You will be able to taylor a firearm to you as you have more choices with the 9mm.

Best to ya.
