Unlike its double-action counterpart, a single-action revolver's trigger only releases the hammer. When the hammer is pulled back to the full-cocked position, the trigger is set and can be pulled to fire a single shot. After a shot is fired, the trigger is locked in place until the hammer is pulled back to the full-cocked position for another shot. The cylinder does not swing out on a single-action. Loading requires the hammer to be pulled back to the half-cock position. Next, open the loading gate, rotate the cylinder to an empty chamber, and insert a cartridge. To eject a cartridge, pull the hammer to a half-cock position, open the loading gate, and rotate the cylinder until a cartridge is visible. When the cartridge is visible, push on the ejector rod until the cartridge falls out. You must perform this action for each cartridge.
Modern revolvers may be safely carried with all chambers loaded. When the hammer and trigger are fully forward at the same time, the transfer bar is lowered out of the firing position and the hammer rests directly on the frame, not on the firing pin. This is why it is important to release the trigger when you feel the hammer exerting forward - this lowers the transfer bar.
Important! The trigger must be pulled while holding the hammer back to lower the hammer without firing the revolver. Don't slip!
Safety First! If you own an old model single action revolver that does not have the transfer bar safety feature, be sure to carry the revolver with the hammer resting on an empty chamber to help prevent accidental discharge caused by a blow to the hammer.
