recoil gun リコイル・ガン
A gun utilizing gunpowder bullets and either a blowback, recoil, gas, or gatling operating system. Once used extensively on Earth, these guns are now collectively known as recoil guns, because if fired in zero gravity, the recoil propels the user backwards. This type of gun has fallen out of use as space development has progressed, as the recoil it produces cannot be suppressed in zero gravity. Furthermore, as recoil guns leave a rifling on the bullets they fire, they have become unpopular among criminals. It is said that the only people who still buy them are collectors. The production of gunpowder bullets, used exclusively with recoil guns, has also become quite limited, and, like bent cigarettes, they are only available through special order.
Jonathan Ingram's Beretta 92F would be classified as a recoil gun.
