Wesson j- frame revolvers were married from a smith and wesson model 36 was it made. The Smith & Wesson Model is a six- or seven-shot double-action revolver manufactured by Smith & Wesson and chambered for the Magnum cartridge . The S&W Model 19 is a revolver produced by Smith & Wesson on its K-frame. The Model 19 is the Combat Magnum (later designated Model 19), with the first serial-number gun (K,) presented to Jordan on November 15,
The hammer was added later and is in the general form of the King Gun Shop modification usually intended for the timed and rapid fire portions of the NRA course. The lock mechanism remained principally unchanged after this model. It would also become very popular with civilian shooters, with several new models being made, including the first snubnosed 2- 2. It is noteworthy that early Victory Models did not always have the V prefix.
Most Victory Models sent to Britain were fitted with 4-inch or 5-inch barrels, although a few early versions had 6-inch barrels. The Victory Model was a standard-issue sidearm for United States Navy and Marine Corps aircrews, and was also used by security guards at factories and defense installations throughout the United States during the war.

Lee Harvey Oswald was carrying a re-chambered Victory Model when he was apprehended on November 22, Field for an economical device for minimizing the flash gap of a revolver between the barrel and the cylinder.

A revolver works by having several firing chambers arranged in a circle in a cylindrical block that are brought into alignment with the firing mechanism and barrel one at a time.
In contrast, other repeating firearms, such as bolt-action, lever-action, pump-action, and semi-automatic, have a single firing chamber and a mechanism to load and extract cartridges into it.
This leaves the trigger with just one "single action" left to perform - releasing the hammer to fire the shot - so the force and distance required to pull the trigger can be minimal. In contrast, with a self-cocking revolver, one long squeeze of the trigger pulls back the hammer and revolves the cylinder, then finally fires the shot.
They can generally be fired faster than a single-action, but with reduced accuracy in the hands of most shooters. The accepted meaning of "double-action" has, confusingly, come to be the same as "self-cocking", so modern revolvers that cannot be pre-cocked are called "double-action-only". Among these are the. In a revolver known as the Medusa M47 was made that could chamber 25 different cartridges with bullet diameters between.
LeMat Revolver, an unusual pinfire cartridge model Revolver technology lives on in other weapons used by the military. Some autocannons and grenade launchers use mechanisms similar to revolvers, and some riot shotguns use spring-loaded cylinders holding up to 12 rounds.
Revolvers do not suffer from this disadvantage. A second revolver may be secured behind the shield to provide a quick means of continuity of fire. Many police also still use revolvers as their duty weapon due to their relative mechanical simplicity and user friendliness. The polymer is only used on the lower frame and joined to a metal alloy upper frame, barrel, and cylinder. Polymer technology is considered one of the major advancements in revolver history because the frame has always been metal alloy and mostly one piece frame design.
The Rhino, built with the U. This is intended to reduce muzzle flipallowing for faster and more accurate repeat shots.
In addition, the cylinder cross-section is hexagonal instead of circular, further reducing the weapon's profile. These were caplocks or "cap and ball" revolvers, because the caplock method of priming was the first to be compact enough to make a practical revolver feasible. When loading, each chamber in the cylinder was rotated out of line with the barrel, and charged from the front with loose powder and an oversized bullet. Next, the chamber was aligned with the ramming lever underneath the barrel.
Pulling the lever would drive a rammer into the chamber, pushing the ball securely in place. Finally, the user would place percussion caps on the nipples on the rear face of the cylinder. Otherwise, the fragments could fall into the revolver's mechanism and jam it. Caplock revolvers were vulnerable to "chain fires", wherein hot gas from a shot ignited the powder in the other chambers. This could be prevented by sealing the chambers with cotton, wax, or grease.
Another solution was to use a revolver with a detachable cylinder design. These revolvers allowed the shooter to quickly remove a cylinder and replace it with a full one. Front reloading a cap and ball pistol.

Fixed cylinder designs[ edit ] A fixed-cylinder Nagant M with gate open for loading In many of the first generation of cartridge revolvers especially those that were converted after manufacturethe base pin on which the cylinder revolved was removed, and the cylinder taken from the revolver for loading.
Most revolvers using this method of loading are single-action revolvers, although Iver Johnson produced double-action models with removable cylinders. The removable-cylinder design is employed in some modern "micro-revolvers" usually in. These weapons are small enough to fit in the palm of the hand. Accordingly, many modern large caliber hunting revolvers tend to be based on the fixed cylinder design. Fixed cylinder revolvers can fire the strongest and most powerful cartridges, but at the price of being the slowest to load and reload and they cannot use speedloaders or moon clips for loading, as only one chamber is exposed at a time to the loading gate.

Releasing the lock and pushing the barrel down exposes the rear face of the cylinder. In most top-break revolvers, this act also operates an extractor that pushes the cartridges in the chambers back far enough that they will fall free, or can be removed easily.
Fresh rounds are then inserted into the cylinder. The barrel and cylinder are then rotated back and locked in place, and the revolver is ready to fire.
However, this design is much weaker and cannot handle high pressure rounds. While this design is mostly obsolete today, supplanted by the stronger yet equally convenient swing-out design, manufacturers have begun making reproductions of late 19th century designs for use in cowboy action shooting. The most modern method of loading and unloading a revolver is by means of the swing out cylinder. An extractor is fitted, operated by a rod projecting from the front of the cylinder assembly.
When pressed, it will push all fired rounds free simultaneously as in top break models, the travel is designed to not completely extract longer, unfired rounds.
The cylinder may then be loaded, singly or again with a speedloaderclosed, and latched in place.

Using the method often portrayed in movies and television of flipping the cylinder open and closed with a flick of the wrist can in fact cause the crane to bend over time, throwing the cylinder out of alignment with the barrel. Lack of alignment between chamber and barrel is a dangerous condition, as it can impede the bullet's transition from chamber to barrel.
This gives rise to higher pressures in the chamber, bullet damage, and the potential for an explosion if the bullet becomes stuck.Gun Review: Smith & Wesson J Frame Revolvers Pistol Handgun
Stronger designs, such as the Ruger Super Redhawkuse a lock in the crane as well as the lock at the rear of the cylinder. This latch provides a more secure bond between cylinder and frame, and allows the use of larger, more powerful cartridges. Swing out cylinders are rather strong, but not as strong as fixed cylinders, and great care must be taken with the cylinder when loading, so as not to damage the crane.
Single-action[ edit ] From Top: Replica of vintage. In a single-action revolver, the hammer is manually cocked, usually with the thumb of the firing or supporting hand. This action advances the cylinder to the next round and locks the cylinder in place with the chamber aligned with the barrel.
The trigger, when pulled, releases the hammer, which fires the round in the chamber. To fire again, the hammer must be manually cocked again. This is called "single-action" because the trigger only performs a single action, of releasing the hammer. Because only a single action is performed and trigger pull is lightened, firing a revolver in this way allows most shooters to achieve greater accuracy.
Additionally, the need to cock the hammer manually acts as a safety. The hammer is pulled back to the cocked position which also indexes the cylinder to the next round. The hammer is released to strike the firing pin. Thus, DA means that a cocking action separate from the trigger pull is unnecessary; every trigger pull will result in a complete cycle. This allows uncocked carry, while also allowing draw-and-fire using only the trigger.
A longer and harder trigger stroke is the trade-off. However, this drawback can also be viewed as a safety feature, as the gun is safer against accidental discharges from being dropped. The second way is double-action, or from a hammer-down position. In this case, the trigger first cocks the hammer and revolves the cylinder, then trips the hammer at the rear of the trigger stroke, firing the round in the chamber.
Note the spurless hammer. Certain revolvers, called double-action-only DAO or, more correctly but less commonly, self-cocking, lack the latch that enables the hammer to be locked to the rear, and thus can only be fired in the double-action mode.
With no way to lock the hammer back, DAO designs tend to have bobbed or spurless hammers, and may even have the hammer completely covered by the revolver's frame i. These are generally intended for concealed carrying, where a hammer spur could snag when the revolver is drawn.
The potential reduction in accuracy in aimed fire is offset by the increased capability for concealment. Only in the s did the semiautomatic pistol begin to make serious inroads after the advent of safe actions.
The reasons for these choices are the modes of carry and use. Double action is good for high-stress situations because it allows a mode of carry in which "draw and pull the trigger" is the only requirement—no safety catch release nor separate cocking stroke is required.
If the hammer was down, pulling the trigger would cock the hammer. If the trigger was pulled with the hammer cocked, it would then fire.
This meant that to fire the revolver from a hammer down state, the trigger must be pulled twice.
