What is Speed Loader? A speed loader is a way to reduce the efforts invested in reloading a firearm. Whether it is a pistol or a rifle or gun, speed loaders are used to load various type of guns. The first speed loader was invented way back in 1879. How much time can you save with a Speed Loader? Loading magazines by hand is time-consuming and strenuous on the fingers and hands, especially when loading several magazines back to back. Also, it's sometimes easy to miss-load a round, creating a higher potential for jamming when firing. Someone who loads magazines often, such as an active-duty soldier or even someone that does manual labor will have calluses in just the right places to help make the job easier. Though, someone that doesn't load magazines often may find themselves with pain-filled fingers after loading several magazines during a day of shooting at the range.
