Hammer Positions

There are three distinct hammer positions on a Colt revolver; two, which are described below, are safety features, while the third, which will be described later, is the COCKED position for firing. HAMMER SAFETY POSITION-With the hammer in the Safety position the sear end of the trigger engages the first notch (safety notch) of the hammer. See Figure 3. In this position, the firing pin does not protrude through the firing pin hole, so that it cannot contact ammunition in the cylinder chambers and the trigger cannot be moved unless enough force is applied to break it or the notch. (Note: Normal trigger pull is 5 lbs. maximum, while excessive force is 35 lbs. or more.)

CAUTION: ALWAYS CARRY YOUR SINGLE ACTION REVOLVER IN THIS "SAFETY" POSITION WITH AN EMPTY CHAMBER IN FRONT OF THE HAMMER.

To put the hammer in the safety position, place your thumb firmly on the hammer spur, (DO NOT TOUCH THE TRIGGER) and draw the hammer back about a quarter inch. When you hear a "click," gently ease hammer slightly forward, allowing safety notch to engage and hold hammer in safety position.

CAUTION: DO NOT ATTEMPT TO ENGAGE SAFETY NOTCH DIRECTLY FROM HALF-COCK OR COCKED POSITIONS unless you release the trigger completely before the hammer reaches the safety position, as the safety notch may not be engaged correctly.

HALF-COCK (OR LOADING) POSITION-With the hammer in the Half-Cock position the sear end of the trigger engages the half cock notch and the cylinder is free to rotate for loading, unloading, inspection and further maintenance. See figure 4. Once in this position the trigger cannot be moved unless enough force is applied to break it or the notch.

CAUTION: NEVER CARRY YOUR REVOLVER IN THE HALF-COCK POSITION AS ACCIDENTAL DISCHARGE MAY BE POSSIBLE IF REVOLVER IS SUBSEQUENTLY DROPPED, MISHANDLED OR MISTREATED.

To place the hammer in Half-Cock position (DO NOT TOUCH THE TRIGGER) put thumb firmly on the hammer spur and draw hammer back about three quarters inch from Safety position. When you hear a "click" gently ease hammer slightly forward allowing Half-Cock notch to be engaged to hold hammer in Half-Cock position.

IMPORTANT: If you draw the hammer too far back another "click" will be heard. This "click" is caused by the bolt engaging the cylinder which will not be free to rotate when hammer is lowered into Half-Cock position. If you find the cylinder locked DO NOT FORCE IT. Simply return the hammer to the Safety position and draw it back again into the Half-Cock position as described in this manual.

The Safety and Half-Cock positions also serve to arrest the forward movement of the hammer and prevent a round being fired should your thumb accidentally slip from the hammer spur. This safety feature is effective provided YOU DO NOT TOUCH THE TRIGGER. IMPORTANT: The Safety and Half-Cock notches in the mechanism are designed to prevent the trigger from being pulled, so DO NOT FORCE THE TRIGGER WITH HAMMER IN "SAFETY" or "HALF-COCK" POSITIONS. The mechanism could be damaged by such action, rendering the revolver unsafe.

When you no longer want the hammer at Half-Cock, place thumb firmly on hammer spur and draw hammer back slightly to disengage Half-Cock notch. Insure that empty chamber remains in front of hammer. Squeeze trigger only long enough to allow hammer to move forward and clear Half-Cock notch, then release trigger completely so that Safety notch can be properly engaged, and lower hammer, controlling its movement with your thumb, into the Safety position. Practice this action with an empty revolver to assure proper feel.

ZlAWARNING: IF YOU DO NOT RELEASE TRIGGER FULLY BEFORE REACHING SAFETY POSITION, SAFETY NOTCH MAY NOT BECOME FULLY AND SAFELY ENGAGED,

A RENDERING IT INEFFECTIVE AS A SAFETY DEVICE.

WARNING: IF REVOLVER IS DROPPED ON HAMMER, IF REVOLVER IS FANNED, OR IF EXCESSIVE FORCE IS APPLIED TO TRIGGER—"SAFETY" AND "HALF-COCK" NOTCHES COULD BREAK, CAUSING ACCIDENTAL DISCHARGE WHICH COULD RESULT IN INJURY, DEATH, OR DAMAGE TO PROPERTY. (Note: Normal trigger pull is 5 lbs. maximum—excis-sive force is 35 lbs. or more.)

RISK OF MECHANISM DAMAGE

IMPORTANT: If you suspect excessive force has been applied to the trigger (35 lbs. or more applied on a plane parallel to the barrel) or if revolver has been dropped or has otherwise received a sharp blow which may also damage or break the notches—have the revolver inspected for safe functioning by a competent gunsmith.

SECTION 4

FUNCTION

Your Colt Single Action revolver will be ready to fire when chambers in the cylinder are loaded with ammunition (see loading instructions), and hammer has been drawn all the way back past Safety and Half-Cock positions to the Cocked position. The Action of "cocking" lowers cylinder locking bolt, rotates cylinder to carry a round of ammunition into alignment with barrel and hammer, raises cylinder locking bolt to lock cylinder and holds hammer under spring tension. When trigger is squeezed, hammer falls forward causing firing pin to pass through the firing pin hole and strike primer of base of cartridge. The energy imparted to the primer ignites it, in turn igniting the main charge which, in burning, rapidly generates extremely high gas pressure to drive the bullet down the barrel. Rifling grooves in the barrel impart stabilizing spin to the bullet so that it will follow a more accurate path to the target.

O MINIMIZE RISK OF UNINTENTIONAL DAMAGE, LOAD LIVE AMMUNITION INTO REVOLVER ONLY WHEN YOU A ARE ABOUT TO SHOOT.

JXCAUTION: BEFORE LOADING STOREKEEPER'S OR SHERIFF'S MODEL MAKE SURE THAT AMMUNITION MATCHES THE CYLINDER INSTALLED and never load a cylinder unless it is installed in the revolver frame.
