To Remove .45 Caliber
Remove the magazine by
pressing the magazine catch. (After removing magazine, look
to see that there is no cartridge left in the chamber.)
Press the recoil spring plug
inward with the index finger of the right hand. Turn barrel
bushing to the left until the plug is free to go forward;
then release tension on the spring gradually to prevent plug
from jumping away. Draw slide back until the rear edge of
the smaller recess in the lower edge of the slide is even
with the rear end of the slide stop; press against end of
slide stop which projects from the opposite side of the
receiver above the trigger guard, and draw out the stop.
This releases the barrel and
slide, which may then together be drawn forward from the
receiver, carrying also the barrel bushing, recoil spring,
and recoil spring guide.
It is not necessary to remove
stocks as all parts of the pistol can be dismounted and
assembled with the stocks in place.
In taking the pistol apart,
use no hammer, as dismounting and assembling is quick and
easy after a little practice.
The hammer should not be
snapped when the slide is removed from the receiver.

Reasonable care should be
taken to keep the magazines from being dented or otherwise
damaged. When placing loaded magazine in the pistol, never
push part way in and then strike it with the hand to drive
it home as it might spring the bottom plate or the inturned
lips at the top of the magazine; it should be inserted in
the handle by a quick, continuous movement, but not slammed
into place hard enough to cause damage.
Use nothing but thin oil for
oiling the arm.
As soon as possible after
firing, the inside of the barrel should be cleaned and
Occasionally a little oil
should be put on the friction points, not forgetting ends of
the safety lock and slide stop plungers.
