Virtually all double-action revolvers of today have a cylinder that swings out of the frame on the left hand side. A latch, located on the left hand side of the frame behind the cylinder on most models, must be moved which unlocks the cylinder so it can be swung out of the frame. An ejector rod that is located at the front of the cylinder can be pushed backward which forces all of the empty cases out at the same time. As a result, loading and unloading are accomplished much faster than with a single-action revolver. However, for a great deal of sport shooting, rate of fire as determined by the speed of loading and unloading is of no importance.

Semiautomatic handguns hold cartridges in a magazine that is contained within the grip. In firing, the force generated by firing a round moves the slide to the rear against a strong recoil spring, and it also cocks the hammer (which may or may not be externally visible). The spring forces the slide forward, which allows it to engage the top cartridge in the magazine forcing it into the chamber. Therefore, the semiautomatic is actually a self-loading handgun. Incidentally, it is sometimes found that a particular semiautomatic handgun will cycle more reliably with some types of ammunition than with others. You may have no way to test this before you buy the piece, but if you find that your pistol “jams” with some particular brand or type of ammunition, by all means try a few others before you assume that the pistol is defective. The experience of this author with several pistols that have been fired with a wide range of ammunition is that most rimfire pistols are remarkably forgiving with respect to type of ammunition used. Of course, 22 LR semiautomatic pistols will not function reliably with 22 Short, Long, or shot cartridges.
