If you have trouble starting the screw into the threads it
may be because of the thread locking compound on the
screw itself. This thread locking compound is a blue-green
color and is important in keeping your extension tight
on the hammer spur. To make it easier to start the screw
you may need to back it out and clean the compound
off of the first thread of the screw. Then reinsert and
tighten lightly.
4. Test the extension by working the hammer through its
full range. Under most circumstances the extension will
operate best when fully forward on the hammer spur. If
there isn’t sufficient clearance between the extension and
scope or if the extension contacts the receiver at full-cock,
it is possible to reposition the extension slightly along the
hammer spur.
5. Once the position of the extension has been finalized it
is important to “set” it permanently in place. Do this by
tightening the set screw enough that it leaves a mark on
the side of the hammer. Then remove the extension.
Support the hammer on a firm work bench or padded
anvil and center punch the mark left by the set screw.
The gun and hammer must be well supported during this
operation (Figure 21).
6. Reinstall the hammer extension in the location deter-
mined previously. If the locking compound has been worn
off of the screw you will want to put a drop of locking
compound (like Loctite
® ) on the threads before inserting.
Position the cut out portion
of the extension to the rear.
