Both NATO and European loadings for the 9mm are hotter than American SAAMI loads. I've heard some say that the standard European load exceeds our +P loads for 9mm. I'm curious about how that came to be. Anyone know of a good source that explains why the standard 9mm in America was established well below the European standard? Also, does anyone know of a source of European load data with powders used in the USA that can be compared to the data in my reloading manuals? With most manufacturers today trying to sell their 9mm world-wide, why has the American standard remained below the European standard even when the pistols must be designed to handle the hotter loads if a manufacturer expects to sell worldwide? Thanks.

For some reason, when the 9mm was introduced to America after WW I, and the ammo companies started loading for it, they loaded it light. I've never seen an explanation for this.

DorGunR. When the 8mm mauser was first designed, it fired a 220 gr. bullet from a bore of .318 inch. Around 1905, the bore diameter was changed to .323 inch and a 150 gr. bullet was used. Because there are rifles in this country in both bore diameters, the ammo companies have no choice but to download 8MM ammo.
As to 9mm, there are some foreign handguns that have found their way into this country that take the 9MM round, but one that is not loaded to full 9mm specs. I can't think of the names of them offhand, but that is probably why 9MM is also underloaded. I looked in my CARTRDGES OF THE WORLD, and the weaker round is the 9MM Glisenti. It is exactly like the 9MM Parabellum, but loaded to a lower pressure. I don't think it's even safe to shoot currnt standard 9MM's in a Glisenti.
