I'll be even more basic.
THE American handgun is.......The revolver.
Other countries make quite nice autos.
The United States ALONE truely understands the revolver.
Sam Colt invented it, and Colt and S&W perfected it.
No other country has ever really understood the revolver and even super high quality foreign made revolvers like the Korth LOOK like cartoon drawings of a revolver.
No matter how well made, foreign designed revolvers just aren't "right".
NO ONE has ever been able to design a revolver that just somehow seems to look, feel, and operate "right".
Although they may work quite well, foreign revolvers like the Korth, Webley, Manurhin, and any of the foreign military revolvers never really measured up to even the cheapest Colt or S&W.
All the foreign revolvers, even of top quality are second rate designs by people who have no idea what a revolver is supposed to be.
John Browning solidified what an automatic should be, and the world took that to heart and expanded on it.
Sam Colt decided what a revolver was to be, and it was "Right" for all time.
The rest of the world, for whatever reason never understood this, and still doesn't.
For that reason, while the automatic belongs to the world, the revolver was, is, and always will be an exclusively American "thing".
