2. (Refer to Figure 4, p. 23). Align hammer in frame and insert hammer pivot

with the grooved end of the pivot on the gate side of the frame. (The long

screw, XR01901, when also inserted on the gate side, will intersect the groove

and lock the pivot in place. See step number 11, p. 25).

3. Replace the loading gate, cylinder latch

and gate detent spring as shown in

Figure 6. Note that the lug on the

cylinder latch fits between the arms of

the gate detent spring and that the end

of one of the arms of the spring is

formed at a 90 degree angle. The

projection thus formed, is designed to

fit through the square hole in the

bottom of the frame and to ride on the

cam surface of the gate pivot. Note also

that this projection holds the loading

gate back and in place.

4. (Refer to Figure 4, p. 23). Depress the upper arm of the gate detent spring

with tip of screwdriver blade and install trigger pivot. Pivot should be

inserted from the gate side of the frame. The non-grooved end of the pivot

should be inserted first. (It may be necessary to manipulate the trigger, the

gate detent spring, and the cylinder latch to align them to receive the trigger

pivot).

5. Insert the base pin, taking care to be certain the ‘dished out’ section of the

base pin collar is adjacent to the bottom of the barrel. The base pin must be

fully inserted and locked in position by the base pin latch. If the base pin is

not fully inserted and locked, the transfer bar may catch under the firing pin

when the hammer is being cocked.

6. (Refer to Figure 7, p. 25). Unhook the ends of the trigger spring (XR03700)

from the grooved retaining pin on both sides of the grip frame.

7. Insert cylinder latch spring and plunger in hole in grip frame. (The spring

goes in first so that the plunger is on top).

8. Insert pawl spring and plunger (plunger goes in the hole first) in the hole in

the left side of the cylinder frame just above the left rear grip screw hole.

9. Install mainspring assembly in the grip frame. Be certain the strut is

positioned properly. See the Parts Drawing for correct strut positioning.

10. (Refer to Figure 7, p. 25). Draw hammer to the rear slightly and place the

grip frame loosely on the cylinder frame. Before pushing the grip frame

forward to mate with the cylinder frame, be certain that:

(a) the cylinder latch spring plunger (XR07700) is positioned so that is will

contact the bottom of the cylinder latch (rather than either side of the

latch),

(b) the pawl spring is aligned to contact the left ‘ear’ of the grip frame (and

not be bent as the ear contacts it).
