The closest comparisons are the 380 ACP, which fires much lighter bullets slightly faster than most .38 Special loads; the 9×19mm Parabellum, which fires a somewhat lighter bullet significantly faster; and the .38 Super, which fires a comparable bullet considerably faster. All of these cartridges are usually found in semi-automatic pistols.
It is essentially a .45 ACP case, necked down to .357, resulting in a cartridge similar in form to the earlier 7.65×21mm Parabellum and 7.63×25mm Mauser cartridges. It was created to be a low recoil target cartridge that would function reliably with multiple bullet types, FMJ to cast lead wadcutters without the feeding problems that straight walled pistol rounds sometimes exhibit.

The felt recoil of a normal handgun in .38 Super is similar to the .45 ACP, but the higher pressure in the .38 Super provides more gas pressure for muzzle brakes. The .38 Super caliber became popular in the early 1980s, and has continued to be popular in the open division after its introduction in the 1993 season.
The standard-issue military .45 ACP cartridge uses a 230 gr (15 g; 0.53 oz) round-nose bullet at approximately 830 ft/s (250 m/s) fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating of 21,000 psi (140 MPa ), compared to 35,000 psi (240 MPa ) for both 9mm Parabellum and .40 S&W , which ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
14.9 g (230 gr) .45 ACP Full Metal Jacketed (FMJ) bullets at a velocity of 259 m/s ± 9.1 m/s (850 ft/s ± 30 ft/s). It also provides protection against the threats mentioned in [Type I]. Level II 9mm +P.357 Magnum: New armor protects against 8 g (124 gr) 9 mm FMJ RN bullets at a velocity of 398 m/s ± 9.1 m/s (1305 ft/s ± 30 ft/s)
The .38 Long Colt's predecessor, the .38 Short Colt, used a heeled bullet of 130 grains (8.4 g) at a nominal 770 ft/s (230 m/s), producing 165 ft⋅lbf (224 J) muzzle energy. The cylindrical "shank" or "bearing surface" of the bullet, just in front of the cartridge case mouth, was .374 or .375 in (9.50 or 9.53 mm) in diameter, the same as the ...
In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound. As an example, the very common 9×19mm Parabellum standard military round is a 7.5 g (116 gr) bullet at velocities typically around 360 m/s (1,200 ft/s). Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr ...
