    So this is a picture of a 8mm 9mm and a 10mm the 8 and 9 like very similar which makes sense but why is the 10mm so much bigger than the other two

    Because they had to make FBI agents feel like girlie men and whine for the .40 S&W.

    Standard AP 10mm Caseless is what they used against Aliens for heaven's sake man!!!

    PS: put a pic of a .40 and a .45 in there bud.

    8mm? What 8mm cartirdge is that? The only one I know of is the 8mm Nambu and it is bottle necked.

    The 10mm was Created by Jeff Cooper as a slightly slower cartridge for the Bren Ten pistol. The FBI went to the 10mm for some field tests. They found that in the 1911 platform it was too much gun for many agents to handle esp women and smaller men (Girly men). The 10mm is far superior to the 9x19mm. It is the only semiauto cartridge that you can hunt with other than the 357 mag Coonan or the Gangster Desert Eagles.

    How about the .460 Rowland? You can hunt with that. About the same ballistics as the .44 mag.

    8mm,9mm and 10mm refers to the size of the bullet it's self. Has nothing to do with the case.

    Here is some .45's. they all look different. But they all have a .45 projectile.

    I kinda presumed 8mm Steyr. As for the pics I thought you might put them all together -- they might all mak better sense then.

    The 10mm is extraordinary.

    Most any .32 Caliber is a 7.92 or 8MM Caliber.

    "Slightly slower" than what? As designed the 10mm was a Magnum powered cartridge. It was slowed/dumbed down to the point the engineers saw they could match the watered down ballisitcs in a cartridge that would fit in a 9mm sized pistol. Hence the .40 S&W (Short & Weak).

    Asking why a 10 mm is so much larger (longer) that the other two is like asking why the .300 Remington Ultra Mag is so much larger than 7 X 30 Waters when they are less than one millimeter different in diameter.

    That is a wild cat and not a factory chambering in any 1911 that I have seen.

    When Jeff Cooper developed the cartridge it was slower than the eventual factory loads. They pumped it up and made it to where it was almost useless as so many couldn't handle the recoil. Then engineers started working on a shorter slower version for people with less than XXL glove size.

    For me though the 40 is head and shoulders above the 9mm and the 45acp. YMMV.....

    True but it is still a SA cartridge you can hunt with. Although they don't make a 1911 in .460 they make a conversion kit for the .45

    All the 10mm is is a larger 40s&w, so more powder more power, but if you not using the 10mm more than just a range or back country back up gun then you are using it completely wrong. The over penetration that the 10mm has will be extremely in safe as a daily carry gun. I've seen the 10mm drop a hog at 25meters if you shoot a human with this round don't be surprised when you hit a innocent person and then sit in jail for manslaughter. Please be responsible when it comes to correct calibers for self defense.

    why use a round made for penetration, power, and longer distance and limit it with a frangible round. At that point you will weaken the bullet to the same ballistics on impact as a regular 40 S&W with less recoil for a faster follow up shot because regardless of how fast or large the round is if you are not able to get a percise shot on the first round then whats the point. If the perp your trying to take down is shooting a 9mm not only does he have way less recoil, faster more accurate follow up shots, he also has a larger magazine. So why use a 10mm for a everyday carry? This is modern day powders and projectiles have come a long way, for example look up brass fetchers 6-7 phase 9mm vs 45acp evaluations of modernday factory self defence rounds on YouTube. You will be surprised what great information came out of his studies.

    Lol. Not too many 9mm guns that carry more than 15 rounds. By your thinking why would you ever use hollow points in a 9mm as it is already an inferior round. With frangible ammo the 10mm is still pushing damn close to 44 magnum forces and instead of pass through you get total force dispersment on your target. So as opposed to (just guessing here) 400 fpe from a fmj 9mm round you're getting 700 fpe+ with the 10mm. Besides whether I shoot the bg in the face with a 9mm or 10mm is irrelevant. He ain't gonna care much.

    Have you ever shot a Glock 20C? The recoil is less than my SW99 .40
    Full power ammo in the 10mm will penetrate about 13" under the FBI protocol. The expansion will be dramatically increased over the same bullet from a .40.

    Calling someone irresponsible for carrying a gun, any gun, is irresponsible. So now you are the sole arbitor of what caliber is "correct" for carry? Come on.
