    9mm bullet is installed in a virtually rimless tapered case.

    is for semi-auto and full auto firearms

    is usually described in metric numbers.

    .38 bullet is installed in a rimmed straight walled case

    is mostly used in revolvers.

    is described by a bastardized system. .38" is the chamber diameter in a revolver cylinder.

    a .38 bullet measure either .357 0r .366 and a 9mm bullet measure 9mm

    The .38 caliber bullet is actually about0.357 inches in diameter. The 9 mm bullet is around 0.352 inches in diameter, or thereabouts.

    It is possible to fire 9 mm cartridges in a revolver chambered for .357 Magnum cartridges -- provided that an interchangeable cylinder for the 9 mm is used.

    You mean of course 9 mm bullet and a 380. 380 is a shorter version of a 9 mm bullet now will you be able to fire a 380 out of a 9 mm pistol? If it's a revolver you will have no trouble whatsoever! But most 9 mm are semi-automatic. You can fire one shell it won't open the slide enough to eject the shell but you can manually operate the slide and kick out the shell . And fire the next one. You don't want to try to fire a 9 mm out of a 380 the guns probably going to blow up in your hand because the pressure is much higher. But yes you can fire a 380 out of a 9 mm manually without any safety concern of it blowing up in your face.

      like 9x57 mauser, 9x56 Mannlicher bolt actions or 9x74R single shot/Drilling used for moose and wild boar hunting Often the 9mm reference is to pistol firing a 9x19 Parebellum load as in Military issue, police issue

    Other than close similarity in diameter they are different. Weights, lengths, design,,all different. Hardly .002" diameter on a micrometer.

    My .380 ACP shoots 9X17 MM perfectly.

    They make moon clips to rim 9MM Luger shooting in some .38 SPL.

      Of course your .380 ACP shoots 9x17mm perfectly, as they are different designations for the same cartridge.  One American and on European.

    If you take 9.00 and subtract .38 the difference is 8.62 inches or mm and that my friend is the difference.

      You don't understand the differences in caliber measuring systems do you?

      some times .003, can be ..020 - there are a few close to .38 diameter bullets- like old colt 38-40 cartridge from black powder days. S&W .38 is .364/366  bullet, about same size as 9mm Markov on some packages..

    Both bullets are equal in bullet diameter, the 9 mm case is about 3/8 of an inch shorter than the . 38
