Take
the trigger mechanism completely apart. On the pivot pins
next to the sear and the trigger you will find a spring
washer-type spacer- toss it in the nearest waste basket.
Take one of the pins to your local hardware store and go
to the section where they have the miscellaneous bits ,
pieces and screws . Look for the nylon bushings with a flange
on one side. Test fit the pin into the bushings and find
the right size - it should be about 1/4 " od . Get
several just in case. You will also need a drill bit that
is the same size as the bushing.
Now, drill out the hole in the trigger and the sear . The
trigger is brass and drills easily but for some reason the
sear was very difficult to drill out- it seems to be very
hard steel. If the holes are drilled out right the bushings
should fit tightly into them. I found some minor filework
necessary to get it right. It doesn't matter which side
the flanges are on but they both need to be on the same
side or the trigger won't line up with the sear. Test fit
the parts to the gun. You will need to grind the flanges
slightly to get a good fit . I did this with the end of
a 1/2 stone on a rotary tool - just be careful to keep it
flat . Once they are the right thickness, everything should
go together fine. Make sure to lube it a little with some
light grease. If its done properly the trigger should be
much improved.
Once thats done take another bushing and set it inside the
top of the trigger spring. I noticed that the end of the
sear where it sits on top of the spring tended to drop inside
the spring and create a grinding noise and some vibration.
Putting a flanged bushing on top of the spring made a big
difference.
Hope
this helps out,
