Journalists are morons
Not a 5.7 caliber !!!
That would be a larger diameter than a .50BMG cartridge bullet or a Desert Eagle .50 caliber cartridge
5.7mm
Browning made a 9mm short
9mm, .380, .38, .357, .356 are very close in diameter
A Colt .44 C&B revolver really fired a .453”-.454” cartridge ball or bullet
A .38 does not fire a .38” bullet
Do a little research people!
An early .38 Colt bullet is much different than a later .38 Colt bullet
An early BP .22 pistol loaded with a modern Smokeless .22 cartridge just might change which hand you write and eat with
If you are not prepared to shoot to kill - stay away from handguns or longguns
PS - Ignore all the media jerks
