Not at all. Revolvers are typically reloaded by inserting fresh cartridges into the chambers one at a time. This is in contrast to autoloading pistols, which are typically loaded with a magazine that holds several cartridges.
Some revolvers use detachable magazines, and there are autoloading pistols that use single-shot or revolver-style magazines. So both revolvers and autoloading pistols can exist without magazines. It just depends on how the gun is loaded and reloaded.
Some revolvers have magazines – they’re just not as common. The reason revolvers typically don’t have magazines is because they hold fewer rounds than pistols (typically 6-8 rounds, as opposed to 10-15 rounds for most pistols), so there’s less of a need for a magazine. Additionally, reloading a revolver is generally faster and simpler than reloading a pistol, so there’s less of a need for a magazine to speed up the reload process. Some revolvers do have magazines, though, such as the Smith & Wesson M&P R8 and the Taurus Judge.
No, revolvers are not the only guns without magazines. Some rifles like the bolt-action rifle do not use magazines either. Instead, rounds are loaded into the chamber one at a time. This is why bolt-action rifles are often used for hunting: They allow the hunter to take his time in lining up a shot, and they also minimize recoil (since there is no need to cycle a new round into the chamber).
No. Pistols, derringers, and some long guns also don’t have magazines.
Revolvers typically don’t have magazines because they hold fewer rounds than other types of firearms and reloading is a slower process.
There are a few revolvers that have magazines, but for the most part, revolvers do not have magazines.
This is because the rounds are stored in the chambers of the gun, which rotate as each round is fired. This design is different from that of most pistols, which have a magazine that stores the rounds and feeds them into the chamber. There are some advantages and disadvantages to both designs, but ultimately it comes down to preference. Some people prefer revolvers because they are simpler to use and less likely to malfunction. Others prefer pistols because they can hold more rounds and are generally easier to reload.
