OPERATION OF
“DOUBLE-ACTION ONLY “ REVOLVERS
(This section applied only to “Double-Action Only” revolvers, identified by their
lack of a hammer...

13
CAUTION:When firing the double-action only revolver,
be sure that the trigger is released completely to its fully
forward position before attempting to pull 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), pulling the trigger
will not fire the revolver. The trigger must be fully released after each
shot is fired. This characteristic is found...

WARNING – CYLINDER INTERLOCK

2. Insert cartridges and gently close cylinder, making sure it is securely latched.
Do not “flip” the cylinder open or shut.
3. The revolver is now ready to fire, either “double-action” by pulling the trigger
through its complete arc for each shot, or “single-action” by cocking the
hammer and then pulling the trigger for each shot. The trigger pull is
somewhat shorter and lighter when the revolver is fired single action, and
this is the preferred mode for precise shots or...

FIRING.
CAUTION–DOUBLE ACTION FIRING
15
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 thru about the last one-
eighth inch of its forward
movement), the trigger...

When firing the SP101 revolver, be sure
all persons are a safe distance to the rear
of the shooter. When fired, all revolvers
discharge hot gas and particles of lead,
powder grains, or lubricant through the
clearance gap between the cylinder and
the rear of the barrel at high speed. This
can injure a person who is standing too
close to the revolver.
When firing the SP101 revolver (or any
revolver), always be certain that nothing
– including your hands – is in the path of
the hot gas and particles which...

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 for...

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.

SPECIAL INSTRUCTIONS FOR 9MM CLIPS
9mm revolvers require special clips to extract cartridges using the ejector rod
because this cartridge has no rim for the ejector to act against. Individual
cartridges may be fired without the clip, but will then require that...

rear of the mainspring strut. Lacking a...

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.
7. 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.
8. Further disassembly is not essential for normal...

NOTE: At this point in reassembly trigger should function to rotate and lock the
cylinder. Pull the trigger a few times, to check proper functioning, as always with
the revolver pointed in a safe direction.
