.380 isnt a .38. its like saying a .45lc is the same as a .45acp. the 9mm, .380, .38, and .357mag, are all the same widths as far as the slug. just some have a longer cartridge making them more powerful. .380 being the weakest, followed by 9mm, followed by .38, and the most powerful being the .357.

usually a small frame gun, and puts a hole in somebody just as big as a .357, its just slower. but there are also some large .380's, like the mac11.

alot of people who have a .45acp will tell you that a .380 is too weak, (but so is a .45). if you want power, get a revolver, a .357 or .44. or if you had to have an automatic and wanted excessive power maybe a 10mm.

middle caliber gun equivalent to 38.

a .38 caliber pistol, equivelent to a 9mm, sometimes a revolver

middle classed gun, pretty good uses 9mm i think
