10mm vs 9mm???

[mikeinla]

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?

[maschronic]

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.

Muzzle energy, ammo cost

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

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.

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

[xounlistedxox]

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?
