While I don’t recommend it except for experienced gun hands, the single-action revolver in .357 Magnum—or any other caliber for that matter—can be concealed and still win a gunfight. You need to learn an important skill: how to reload quickly, and that means learn to use the ejector rod! Too many people don’t master this simple mechanism. It is possible for someone skilled with a single action to pop out the empties and reload even on the run. The Ruger New Vaquero and newer model Blackhawks have an indexing feature that lines up the cylinder chambers with the loading gate. It is fast and reliable. Learn to pull cartridges from loops one-handed and load them while the sixgun is held in the other hand.
