LOADING THE
REVOLVER.
TO LOAD AND FIRE
Be sure the revolver is pointed in a safe direction and is
never cocked while loading.
1. Press the crane latch and guide cylinder out of frame to the left to its loading
position (See Figure 3).
!WARNING – CYLINDER INTERLOCK
➧
When correctly operated, the cylinder
cannot be opened when the hammer is
cocked, and the hammer/trigger
mechanism  is not able to be operated
until the cylinder is locked shut.
However, this safety interlock can be
intentionally...

5.DO NOT HOLD THE REVOLVER BY THE BARREL OR CYLINDER WHEN
FIRING.
!CAUTION–DOUBLE ACTION FIRING
When firing in the double action
mode, be sure that the trigger is
released completely to its fully
forward position before pulling the
trigger for a subsequent shot. If
the trigger finger is allowed to
interfere with the full recovery of
the trigger (preventing it from
moving through about the last
one-eighth inch of its forward
movement), the trigger cannot be
pulled again for another discharge.

TO UNCOCK (DECOCK) THE REVOLVER
If your revolver is cocked, and you wish to let the hammer down to its forward
position (against the frame), proceed as follows: USE EXTREME CARE WHEN
ATTEMPTING TO DECOCK THE REVOLVER, AS THE THUMB SLIPPING
DURING THIS PROCESS CAN RESULT IN AN ACCIDENTAL DISCHARGE IF
THE TRIGGER IS HELD TO THE REAR.
1.Make certain that the revolver is pointed in a safe direction(See Rule 2, Page
33).
2. Make certain both hands are dry and not impeded in any way – gloves,
bandages,...

15
Practice this important gun handling skill with an unloaded revolver until you
have developed the proper control and ‘touch’ to decock your revolver safely. The
key to safe decocking is having the weight of the revolver controlled with one
hand, while the thumb and forefinger of the ‘shooting  hand’ control the
hammer and trigger. Improperly restraining the trigger during this procedure
may result in the hammer not resting fully against the frame. If this should
occur, carefully repeat the procedure...

Always unload a firearm before
cleaning, lubrication, disassembly
or assembly.
Never remove or install a loaded
cylinder – it can fire if dropped or
struck.
16 NOTE:  When ejecting fired cartridge cases, position the revolver at a
high angle so the cases will come fully out of the chambers and not slip
under the ejector. This high angle positioning is not necessary when
ejecting unfired cartridges.

DISASSEMBLY
Read instructions before disassembling a gun.
1.BE CERTAIN THE REVOLVER IS UNLOADED BEFORE DISASSEMBLY.
2. Using a properly fitting screwdriver,
remove grip screw. Remove pistol grip
inserts from grips. Grip panel locator may
then be removed. Pull grip downward off
frame. Take care not to lose the disassembly
pin, which may fall free when the grip is
removed.
3. Cock the hammer. Insert disassembly pin
about one half its length into the hole at the
rear of the mainspring strut (See Figure...

18
NOTE: If you cannot supply sufficient force to the plunger using the mainspring
assembly as a “tool”, then use a screwdriver of appropriate size and insert
through hole in frame. It may be necessary to slightly depress the trigger while
removing the trigger guard assembly.
8. Cradle the revolver frame in your left hand and with the thumb of your right
hand press cylinder latch button, swing out cylinder assembly and remove it
forward from the frame.
9. Further disassembly is not essential for normal...

Firing a revolver with oil, grease, or any
other material even partially obstructing the
bore may result in damage to the revolver
and serious injury to the shooter and those
nearby.
Do not spray or apply lubricants directly on
ammunition. If the powder charge of a
cartridge is affected by the lubricant, it may
not be ignited, but the energy from the
primer may be sufficient to push the bullet
into the bore where it may become lodged.
Firing a subsequent bullet into the
obstructed bore may damage the...

20
If lead bullet loads are fired extensively, lead build-up may cause cylinder
binding. Lubricate the cylinder crane gap with Break-Free® CLP or some other
lubrication which meets mil. spec. Mil-1-63460 to prevent this condition.
STORAGE
GUNS SHOULD NOT BE STORED LOADED!
Do notkeep your revolver in a leather, fabric or canvas holster when it is stored.
These materials attract moisture, even though the holster may appear to be
perfectly dry.
TO RENDER THE REVOLVER INOPERATIVE FOR SAFE STORAGE
With the...

Never place or store any firearm in
such a manner that it may be
dislodged. Firearms should always be
stored securely and unloaded, away
from children and careless adults. Use
the locking device originally supplied
with this firearm for storage.
The use of a locking device or safety
lock is only one aspect of responsible
firearms storage. For increased safety,
firearms should be stored unloaded
and locked in a location that is both
separate from their ammunition and
inaccessible to children and any...
