There were many changes in weaponry from World War I-II. The machine guns were made lighter, planes were constructed to be better fighters and bombers, submarines were made more effective, tanks were given bigger guns and more armour, the sub-machine gun was invented, and the first semi automatic combat rifles were invented.
Some guns stayed in the arsenal like the Springfield rifle, different types of Mauser rifles, and the 1911 semi-automatic .45 pistol.

As grisly as it is referring to warfare, the weapons of World War I changed warfare by making it much more efficient. WW I was not the first use of the machine gun, but it was the first sustained use of the water cooled machine gun, which could fire 500+ rounds per minute, hour after hour. In research done after that war, the machine gun was voted the most destructive weapon of the war by all combatants.
