Are revolvers the only guns without magazines?

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.
