Any time you see a revolver that doesn’t have a hammer, you know it’s a double-action. A character would just pull the trigger to fire. Nope, it doesn’t have an external hammer. This is a Smith & Wesson Model M&P 340 revolver. Here’s what one of those hammerless revolvers looks like: They’re not “hair triggers,” and they take a serious squeeze to fire. It’s hard to explain that without putting a revolver in your hands and showing you. Unlike other firearms, these triggers offer more resistance. Others offer the option of using a hammer just like a single-action revolver, but it’s not a requirement.Įither way, the primary method double-action revolvers use to prevent accidental discharges is in the trigger pull. In fact, some double-action revolvers don’t have external hammers at all (they’d be called “hammerless revolvers” generally or “striker fired” specifically, depending on mechanical set up). With double-action revolvers, the shooter can just pull the trigger without cocking the hammer first. Most modern revolvers are… Double-Action Revolvers However, single-action revolvers are old hat. That cocking requirement (band name, called it) acts as a sort of safety all on its own. Not all revolvers have external hammers, but many do. For reference, here’s what a hammer looks like: If it’s not, simply pulling the trigger won’t fire the gun. With a single-action revolver, the hammer must be pulled back (i.e. By the way, an “action” is the mechanism a firearm uses to fire and cycle ammunition. What those are depends on the type of action the revolver uses. By design, a loaded revolver will not fire unless some specific things happen. Just because it’s called a “safety” doesn’t mean it’s the only way to prevent an accidental discharge. A safety is a mechanical component of a firearm. If the thought of a revolver without a safety gives you a sense of uneasiness, I can tell you the feeling is unwarranted. What Can Characters Do Instead of Switch Off a Safety? Stop, Hammer Time The rule of thumb is easy enough to remember, though: Revolvers don’t have safeties. Otherwise, you’ll wind up looking like someone who can’t tell the difference between a revolver and a revolving door. Then make sure you point out the specific model of revolver in the story. When writing, assume all revolvers do not have safeties unless you can prove otherwise through research. Because of their lengthy history, revolvers with safeties do exist. This is as close to a hard and fast rule as you’ll find in the world of handguns. There isn’t a switch or other device to press before the revolver can be fired. The short answer is no, revolvers do not have safeties in the same way some semi-automatic pistols do. Mention that specific model in the story. TLDR: Assume that revolvers don’t use safeties unless you can prove otherwise through research. The vast majority of revolvers do not use safeties. Instead of a switch or button, it uses what’s called a “grip safety.” It sits behind the grip, and must be pressed (i.e. It’s one of the few revolvers to use a safety.
